There are several works about radar systems in millimeter-wave frequencies for automotive applications and the objective is to go beyond and to develop a lightweight, small and low-cost surveillance radar based on vehicle collision avoidance technology. In this paper, the design of the radar sensor at 77 GHz and the implemented signal and data processing are presented. The sensor is based on hybrid technology: microstrip, waveguide and MMIC. The signal and data processing carries out a Doppler processing and a target tracking.","PeriodicalId":376019,"journal":{"name":"2015 European Radar Conference (EuRAD)","volume":"79 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128238105","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}

A Neural Network-based Constant False Alarm Rate (CFAR) technique, NN-CFAR, is compared with reference detection schemes based on Doppler processors and conventional CFAR detectors. In these reference solutions, although CFAR techniques are designed for a desired false alarm rate, PFA, we prove that the final PFA rate is higher than the desired one. In this paper, a detection performance improvement is obtained with a detector that is a better approximation to the Neyman-Pearson detector based on the generalized Likelihood Ratio (selecting the maximum filter bank output), and uses a unique CFAR detector. Due to the non-linear nature of the maximum function, conventional CFAR detectors are not suitable. The improved detector is designed and applied to real data acquired by a coherent and pulsed radar system at X-band frequencies. Results prove that the NN-CFAR provides a higher probability of detection while fulfilling the PFA requirement.","PeriodicalId":376019,"journal":{"name":"2015 European Radar Conference (EuRAD)","volume":"401 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115918805","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 significantly high attenuation caused by the soil properties is the main challenge for their feasibility. This challenge is accentuated with Impulse Radio Ultra-Wide Band (IR-UWB) WUSN because of the very low transmitted power. This paper first studies the impact of the soil on performances of a new small UWB buried antenna and then analyzes the effect of soil properties on the communication link from underground to aboveground. This study includes the effect of soil moisture, burial depth and frequency. Measurements are achieved in a sample of soil composed of standard pebbles used in railway (railroad ballast). The simulations and measurements results show that with short distances and low soil moisture underground to aboveground UWB communication is possible.","PeriodicalId":376019,"journal":{"name":"2015 European Radar Conference (EuRAD)","volume":"126 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117344082","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 wake turbulence hazardous flows can dissipate quicker because of decay due to air turbulence or be transported out of the way on oncoming traffic by cross-wind, yet wake turbulence separation minima do not take into account wind conditions. Indeed, for safety reasons, most airports assume a worst-case scenario and use conservative separations. However, with the aid of accurate EDR (Eddy Dissipation Rate) retrieval by Ultra-Fast High-Range Resolution X-band Electronic-Scanning radar sensors, more efficient intervals can be set, particularly when atmosphere is unstable and turbulent, accelerating Wake-Vortex decay. Depending on traffic volume, these adjustments can generate capacity gains, which have major commercial benefits.

The antenna showed a wide bandwidth with the dimension of 7.7×6.7×2.5mm for the lower dielectric resonator and 8.7×7.7×3.3mm for the upper dielectric resonator. Thus the maximum dimension is 0.23 λ0×0.20 λ0 at 8GHz which is very compact. This makes it very appropriate for array applications to reduce the direct mutual coupling through near-field. The antenna has been manufactured and characterized. For the fabricated antenna the -10 dB impedance bandwidth is 20% and operating frequency from 7.4 to 9GHz.

In this paper, the scaling property of the FRFT spectrum is studied in depth and the approximate similarity between the FRFT spectra is presented. The analytical results show that the approximate similarity can be observed in some specific FRFT spectra of a time signal, which correspond to some specific transform orders (or rotating angles). In other words, the FRFT spectra of a time signal are approximate fractal at some specific transform orders.

The final goal of spectrum monitoring is to recognize which frequency channels of the radar spectrum are occupied over a certain time period. In order to analyze the whole wide spectrum in real time, the time signal samples must be collected at a much lower rate than the Nyquist rate corresponding to the highest frequency of the considered spectrum. This paper proposes a novel approach based on the suitable correlation and averaging of a number of parallel asynchronous channels, each of which is heavily undersampled with respect to the Nyquist rate. We demonstrate that the analysis of the large spectrum is possible by applying our approach by using a limited number of asynchronous channels.","PeriodicalId":376019,"journal":{"name":"2015 European Radar Conference (EuRAD)","volume":"56 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134467004","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}

This radar uses the so-called the “signals of the opportunities” which are already in the environment. These opportunistic signals can be of different types, both in terms of frequency and modulation type. Therefore, instead of designing a separate hardware receiving system, a better approach will be design a single software defined receiver having capability to capture any signal of interest by just changing antenna system. This paper presents the development of a state of the art multi-channel, multi-band software defined passive radar. The complete hardware system with multi-channel receiver, and different antenna system has been designed, to give the system software-defined radio capability. The full chain of the signal processing algorithms for target detection will be presented. The algorithms include beamforming, space-time adaptive processing (STAP), and constant false-alarm rate (CFAR) detector framework. More emphasizes will be on the STAP algorithm and CFAR detector. Actual experimental data captured with a circular array is used to validate the system design and signal processing algorithms.","PeriodicalId":376019,"journal":{"name":"2015 European Radar Conference (EuRAD)","volume":"289 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132313153","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}
