The Optimization of Radar Echo Pulse Compression Algorithm Based on DSP

Radar signal processing is usually involved in a large amount of complicate tasks processing and repeated computations. Hence, DSP chips are always used in this field because of its real-time signal processing capacity. In this paper, an optimization scheme of radar pulse compression algorithm is addressed based on TMS320C6678 DSP platform. First, radar echo pulse compression algorithm is realized on DSP platform according to the MATLAB code. Then we use compile options optimization, lookup table optimization, library function optimization, algorithm optimization, and cache optimization to further increase the code efficiency. Exactly processing times are given before and after every optimization method. It can be seen from the experiment results that the processing time is distinctly decreased after optimization. The optimization methods proposed in this paper are proved to be effective.
