This approach is thought to dramatically improve the current generation of systems as it leverages the adaptivity of the sensor to the changing environments in which radars operate. The sections that follow illustrate how the Digital Array Radar (DAR) and advanced digital signal processing might be the enabling system architecture and technologies to implement a CR. In this regard, Adaptive Beam Forming (ABF) algorithms, which adaptively suppress possible interferences impinging on the array antenna, are one of the key features CR should possess to minimize the jammers and maximize the performances. Possible implementations of two ABF architectures and three algorithms are analyzed, and their performances evaluated in the case of analogue inter-channel receiver mismatch present among the receivers. In greater detail, two algorithms leveraging the DAR architecture are analyzed and their performances evaluated against the analogue formed beams approach that was used in the previous generation of radar sensors. The performances of the three algorithms are assessed as far as cancellation capability of both main beam jammer and sidelobe jammer is concerned, in presence of inter-channel phase and amplitude mismatches among the analogue receivers.","PeriodicalId":236783,"journal":{"name":"2021 IEEE 8th International Workshop on Metrology for AeroSpace (MetroAeroSpace)","volume":"72 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-06-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130665268","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}

It aims to perform the first direct monitoring of the martian suspended dust, measuring grain concentration and size distribution. In an OPC single dust grains are sampled in an illuminated spot and their size is retrieved based on the amplitude of the scattered light signal. In this study we analyze the possibility to determine the grain size using an alternative approach based on the durations of the signals rather than their magnitude. For this purpose, we studied the motion of the sampled grains by using a Computational Fluid Dynamic (CFD) simulation, to assure the consistency of the method. We have then performed a laboratory test campaign in martian simulated environment, to measure the signal durations relative to different monodispersed samples. The test results are here presented and compared with the numerical ones obtained using the CFD simulations. Using the acquired data, we present a preliminary duration-diameter calibration function, discussing the pros and cons of this method and how it can support the standard OPC one based on the signal magnitude.","PeriodicalId":236783,"journal":{"name":"2021 IEEE 8th International Workshop on Metrology for AeroSpace (MetroAeroSpace)","volume":"63 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-06-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126615570","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 SCIROCCO arcjet plasma tunnel, is the most powerful PWT in the world used to test the materials of TPS (Thermal Protection System) in the atmospheric entry phase. The methodology focuses on the radiation emitted by the test article in the VIS- NIR (i.e. Visible- Near Infrared) spectral ranges, from which the surface temperature and the emissivity values can be obtained. A UV nikkor camera connected to a compact spectrometer framed the lateral side of a C/SiC test article flap, subject to a known PWT fluid-dynamic flow condition expressed in terms of total pressure P0, total enthalpy H0 and air mass flow rate. A spectrometer with sizes of centimetres was used. It consisted of a commercially available Ocean Optics USB 2000, characterized by no moving parts and no cooling sensor with a 600 gr/mm diffraction grating.","PeriodicalId":236783,"journal":{"name":"2021 IEEE 8th International Workshop on Metrology for AeroSpace (MetroAeroSpace)","volume":"132 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-06-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114522126","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}

In this frame, the monitoring and, if necessary, the update of the sensors' calibration parameters is of utmost importance to correctly evaluate the positions of tracked objects. In this work, a method for the metrological characterization of ground-based sensors for SST applications is implemented, and the performance of the developed sensor calibration tool is assessed. Starting from the acquisition of information about the sensor and data from Tracking Data Messages and Orbit Ephemeris Messages, and assuming a Gaussian distribution for all the observed parameters, the tool computes the residuals and outputs the main statistics for all the parameters of interest. The distributions of the residuals are analyzed to evaluate the statistical significance of the results and the robustness of the hypothesis of Gaussian distribution.","PeriodicalId":236783,"journal":{"name":"2021 IEEE 8th International Workshop on Metrology for AeroSpace (MetroAeroSpace)","volume":"134 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-06-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115424413","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}
