A real-time receive method of wideband radar based on subband pulse compression

The data rate with high capacity and speed of wideband signal makes its real-time processing limited by hardware and software. In this paper, wideband signal is made pulse compression based on subband pulse compression system. It is used uniform complex modulation to generate analysis filter bank and synthesis filter bank, then signals are processed in each subband. The processed results of simulated and measured datas indicate, that the parallel means of subband pulse compression raises the operation speed and improves real-time processing performance of the system, selecting proper subband number according to the data quantity when the result closed to that of directed pulse compression.
