Nevertheless they require filtering at the receiver that can serve for sidelobe suppression in order to avoid target masking. However unmasking is not the only concern, it is crucial to evaluate the filtering scheme both in terms of sidelobe suppression capability but also in terms of output signal to noise ratio. This last criterion is essential when aiming at detecting also weaker reflections. In this paper the theoretical performance of the reiterated filtering technique based on LMMSE is derived and compared to the matched filter. The unmasking capabilities are relevant, but also output power figures. Moreover the performance of reiterated LMMSE is evaluated for OFDM communication-encoded radar waveforms.","PeriodicalId":181361,"journal":{"name":"2008 European Radar Conference","volume":"338 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115570655","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}

79GHz automotive short range radar sensor based on single-chip SiGe-transceivers 基于单片机sige收发器的79GHz汽车近程雷达传感器

Maurer","doi":"10.1109/EUMC.2008.4751781","DOIUrl":"https://doi.org/10.1109/EUMC.2008.4751781","url":null,"abstract":"Today automotive short range radar sensors are only available for the 24 GHz band. But in the EU the production of ultra-wideband sensors is limited to 2013 for the 24 GHz band, after 2013 the 79 GHz range must be used. This was the impact to develop a single-chip SiGe RF-transceiver for the 79 GHz-band on Infineon¿s B7HF200-Process with transition frequencies above 200 GHz. The power spectral density limit of -9 dBm/MHz for the 79 GHz-band is much higher than the -41.3 dBm/MHz limit for 24 GHz. Therefore the built prototype is a FMCW radar and no pulse radar in order to achieve a higher Signal-to-Noise Ratio. The required frequency ramp generation according to the FMCW-Principle is realized without a Phase Locked Loop(PLL), but by controlling digitally the tuning voltage of the VCO with help of a D/A-converter. The non-linearity of the VCO tuning law is compensated by measuring the frequency of the divider signal. Two bistatic transceiver variants have been realized: ATRX2 has one transmit and three receive channels, while ATRX3 has two switchable transmitters and two receivers. An RF-board has been designed for each chip, where low-cost patch antennas have been applied, optimized for a short range system. In the following the configuration for both chips is explained and measurement results are presented in order to demonstrate the angle detection capabilities.","PeriodicalId":181361,"journal":{"name":"2008 European Radar Conference","volume":"11 3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116440863","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}
