In particular, helicopters and other targets with rotors, as for instance miniature Unmanned Aerial Vehicles, exhibit peculiar characteristics in the radar return that can be used for their recognition. In this paper a novel algorithm to address the problem of micro-Doppler signature unmixing is proposed, exploiting the signal separation capabilities of the Independent Component Analysis (ICA). The core of the algorithm is represented precisely by the use of the ICA procedure, that has been already proved to be a very effective technique for separating hidden information in mixtures of observations. ICA has been successfully employed in several applications such as wireless communications, radar beamforming, trace-gases unmixing and medical imaging processing. The helicopter's rotor blade signature unmixing from a multi-static radar system is considered as case study and results obtained through the application of ICA to simulated multi-component micro-Doppler signatures show the capability of the proposed approach to successfully accomplish the unmixing operation.","PeriodicalId":229414,"journal":{"name":"2017 IEEE International Workshop on Metrology for AeroSpace (MetroAeroSpace)","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132980579","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Typically, these are obtained by auxiliary sensors directly providing the reference angles (e.g. nose-boom vanes) or by analytically reconstructing them using calibrated airspeed measurements and inertial data. With reference to this second methodology, this paper proposes a novel approach, in which the reference data for the flow angles calibration are obtained by using measurements coming from an inertial navigation system and an air data sensor. This is obtained by using the Kalman filter theory for the evaluation of the reference angle-of-attack and angle-of-sideslip. The methodology aims to lower the development costs of advanced aircraft. The designed Kalman Filter has been implemented in Matlab/Simulink and validated using flight data coming from two very different aircraft, the Piaggio Aerospace P1HH Medium Altitude Long Endurance (MALE) Unmanned Aerial System (UAS) and the Alenia-Aermacchi M346 ‘Master’ transonic trainer. This paper illustrates some results where the performance is evaluated by comparing the filter results with the data coming from high-accuracy nose-boom vanes.","PeriodicalId":229414,"journal":{"name":"2017 IEEE International Workshop on Metrology for AeroSpace (MetroAeroSpace)","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-06-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123895418","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The approach is focused on reducing the design cost and time to market mainly adopting a design flow which allows to easily estimate the system performances and the use of commercial off-the-shelf (COTS) parts. At the same time, it mitigates the risks typically associated with the use of such components. It is based on a programmable, flexible and low-cost electrical ground support equipment (EGSE) associated with the use of a suitable simulation technique. In particular, a methodology for RF system design is discussed and how the EGSE may be used as alternative way to perform functional test and obtain rapidly the results. The EGSE, associated with the simulation model, may also be used to predict the behavior of COTS components over different operation conditions, such as the harsh environment of space. An example of an intermediate frequency (IF) filter designed for a telemetry and telecommand (TMTC) system is presented. The proposed methodology has been successfully applied to the filter design.","PeriodicalId":229414,"journal":{"name":"2017 IEEE International Workshop on Metrology for AeroSpace (MetroAeroSpace)","volume":"84 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-06-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127474931","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These activities require both the identification of areas of interest and the deployment of suitable assets. The types of assets to be deployed depend on different aspects such as their endurance, coverage and cost. The Joint Research Centre (JRC) together with the Department of Aeronautic and Space Engineering at the Politecnico di Torino, have developed two complementary low-cost radar systems on board of an aerostat and of a drone. A Frequency Modulated Continuous Wave (FMCW) radar has been identified as the technical solution, whereas an integrated IMU/GPS platform has been used as navigation engine. The synchronization between units is fundamental, therefore various solutions have been investigated. The selected approach exploits the time-referenced matching between radar and navigation datasets. To evaluate the performance of the assembled system, several tests have been carried out in pre-operational conditions with the radar performing several azimuthal scans with fixed elevation angle. From the results, no drift nor bias in the attitude parameters have been observed. Moreover the adopted integration strategy allows reconstructing the polar radar picture, exploiting the synergy between the radar and the navigation units. The obtained radar pictures are consistent from scan to scan and correctly characterize the actual scenario.","PeriodicalId":229414,"journal":{"name":"2017 IEEE International Workshop on Metrology for AeroSpace (MetroAeroSpace)","volume":"108 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-06-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132284536","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

For autonomous or aided operations (e.g. automatic or aided landing), it is crucial to have on board an effective suite of sensors allowing navigation in unknown environments. This work performs obstacle detection and attitude estimation for a small quad-rotor by using low-cost sensors, namely, a Sonic Ranging Sensor (SRS) and an InfraRed Sensor (IRS), widely used in mobile applications for short distance measurements. Both sensors were controlled and managed by a microcontroller (Arduino Mega 2560) and synchronized at 2-Hz sampling. Attitude estimation was performed using multiple distance measurements between a solid surface (e.g. wall or ground) and the SRS/IRS sensors. A short range of 20–150 cm has been considered in order to assist the UAS landing procedure. The main objective was to integrate the SRS and IRS measurements for accurate distance and attitude estimation by means of variance minimization. Simulations and experimental results show the feasibility of low-cost sensor fusion for obstacle detection and ranging applications on a small rotary wing UAS.","PeriodicalId":229414,"journal":{"name":"2017 IEEE International Workshop on Metrology for AeroSpace (MetroAeroSpace)","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-06-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126581467","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To lower maintenance costs new systems have been thought to substitute human workers inspecting the PV plants. The employment of Unmanned Aerial Vehicles (UAVs) has allowed realizing a fast detection of defects and problems arisen in PV plants thanks to the fusion of computer vision algorithms and high accuracy Global Navigation Satellite System (GNSS) positioning techniques able to detect and tag anomalies and identify the defective panels. Authors in this paper intend to present the state-of-the-art in the Computer Vision field applied to PV plant inspection and to thermal anomalies detection over the panels. In addition, different data sets have been recorded and compared for geo-referencing the solar panels. They have been derived through the U-blox NEO-M8N installed on board of the UAV used for inspection. Although the U-blox NEO-M8N measures are less accurate than the classic RTK GNSS ones, the measurements obtained with this handset introduce a very interesting novelty since initial services of the Galileo constellation, supported by the NEO-M8N GNSS module, have become available only since last December. Future testing and validation will be performed by using geo-referenced data from the RTK GNSS receiver, that has been ordered with a specially customized antenna whose specifications have been properly designed and sent to the manufacturer for its fabrication. Next campaigns will allow to get results also from this RTK receiver and to properly validate the proposed algorithm, by comparing new results with those found through the employment of U-blox receiver.","PeriodicalId":229414,"journal":{"name":"2017 IEEE International Workshop on Metrology for AeroSpace (MetroAeroSpace)","volume":"1219 ","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"120940600","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
