A high-speed real-time digital pulse compression system based on TMS320C6201

The linear frequency-modulated pulse is one of the most important large time-bandwidth product signals, which demands large calculations for digital processing. In this paper, methods to improve the parallelism of FFT calculation in a VLIW architecture processor are studied, and a modified fixed-point FFT algorithm is promoted to meet the need of computation speed and accuracy. Then a high-speed real-time digital pulse compression system based on the TMS320C6201 is realized, it can implement DPC processing within 124 /spl mu/s, which is very close to the top performance of the TMS320C6201. The whole system has been applied in some radars and proved stable and reliable.
