An Optimized Parallel Pulse Compression Algorithm Based on Multi -Core DSP

Aiming at the rising demand of signal processing in modern radar system, and the increasing requirement of real-time performance in battlefield environment, an optimized parallel pulse compression algorithm based on multi-core DSP was proposed. Using the DIT-FFT principle, The FFT of a large-point pulse could be decomposed into four quarter-length FFTs, and then parallel computed by four cores of DSP, utilizing the SIMD (Single Instruction Multiple Data) instructions and the built-in functions. The simulation results showed that the algorithm proposed in this paper significantly shortened the cost time of pulse compression, and improved the real-time performance of the system.
