The UWB MIMO radar utilized a combination of two-way multiple signal classification (MUSIC) algorithm and majority decision scheme. Numerical simulations were carried out to evaluate the performance of the proposed scheme while detecting Weibull targets using UWB signals with different bandwidth. It was found that the estimation performance improved with increasing signal bandwidth.","PeriodicalId":241445,"journal":{"name":"2014 11th European Radar Conference","volume":"44 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-12-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128266341","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 MWR is a dual frequency Noise Injection Radiometer working at K and Ka band (23.8 & 36.5 GHz) embarking a main reflector antenna and a dual frequency horn for autonomous calibration.

The system transmits a continuously repeated signal. Hence the received signal contains a large contribution from direct signal and static clutter interference. The signal processing ensures that the micro-Doppler signatures are unaffected by these interferences, and explicit cancellation techniques are not needed. Both main and tail rotors can easily be identified as sharp “flashes” in the cross correlation function, and information such as rotor speeds and the number of blades of the rotors may be extracted and used in target classification.","PeriodicalId":241445,"journal":{"name":"2014 11th European Radar Conference","volume":"35 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-12-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126573729","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}

Ideal 64-QAM symbols, zero power components, and random segments with mean power equal to the acquired signal power, are used for this purpose.

We assumed the use of two 300-MHz class wideband channels in the 21.4 to 22.0-GHz band and devised an array-fed imaging reflector antenna (array-fed IRA) to supply enough power for a transponder with such a wide band. The array-fed IRA is an effective means of exploiting limited resources because of its ability to control radiation patterns; the 21-GHz band suffers from severe fading due to rain. To confirm the feasibility of the array-fed IRA system, we designed an engineering model of an array-fed IRA for a 21-GHz band broadcasting satellite. The engineering model has a feed array that consists of 32 horn antennas. To improve the accuracy of the antenna's arrangement, we combined the 32 horn antennas into one unit. To evaluate the characteristics of this unit type feed array, we fabricated and tested a 32-element horn antenna array.","PeriodicalId":241445,"journal":{"name":"2014 11th European Radar Conference","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-12-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115036108","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}
