Abstract
Conference Title: ICASSP 2016 - 2016 IEEE International Conference on Acoustics, Speech and Signal Processing (ICASSP) Conference Start Date: 2016, March 20 Conference End Date: 2016, March 25 Conference Location: Shanghai, China Passive bistatic radar (PBR) systems use existing RF broad - 1 cast and communication signals in the environment for surveillance and tracking applications. GSM mobile com - 1 munication signal based PBR systems are suitable for short-range surveillance systems, but the low-bandwidth of the signal results in low range resolutions when classical cross-correlation based processing is used for target detection. An alternative and more robust approach based on compressive sensing (CS) is proposed here to achieve high range resolution 1 by performing fine gridding for the target scene. To avoid the 1 increased coherence and computational load associated with the fine gridding, preprocessing steps are introduced in this paper, which involve choosing a suitable CS basis by application of spectral and subspace transformations. By so doing, resolution improvement is achieved when a single channel GSM signal and CS are employed for target detection.
