Passive coherent locator signal processor on IBM Cell broadband engine (Cell BE)

Experimental research of passive bistatic radar based on pipeline processing

“…Batch processing is a very efficient method to execute the cross‐correlation processing [10, 11]. The procession divides the whole reference and surveillance data into many segments.…”

“…The detection threshold of one cell is determined by the average power of the other cells in both range and Doppler directions. There is a reference window to cover the cells to calculate the threshold, and there are two types of reference windows for the CA‐CFAR detection of two‐dimensional range‐Doppler map, that are rectangle reference window and criss‐cross reference window [10, 13], as Fig. 7 shows.…”

“…In [8, 9], the method combined use of GPU and CPU for PBR signal processing was studied, that uses CPU cores to solve the problem such as flow control, and use GPU cores to execute the process calculation as fast as possible because of the intrinsic parallel feature of GPU. In [10], the PBR signal processing based on cell BE processor was studied, the main signal processing steps based on cell BE processor were put forward. In the method, the signal processing algorithms should be contrived according to the specific chips.…”

Efficient architecture and hardware implementation of coherent integration processor for digital video broadcast‐based passive bistatic radar

“…Regarding the hardware implementation of coherent integration for PBR, a system based on IBM Cell BE was presented in [25]. Subsequently, a real‐time system using graphic processing unit (GPU) was developed in [26, 27] to speed up the signal processing chain.…”
