pulse compression is used to improve the radar resolution.With the development of wide band radar systems
the points of pulse compression become larger and larger.A method of fast implementation of ultra-long points pulse compression in frequency domain based on 2-D FFT algorithm is proposed.TMS320C6678 EVM board is used to test the new method.The experiment result shows that the efficiency of the proposed method is improved by more than 20% compared with the traditional methods.128K points pulse compression can be finished in about 0.81ms by only one 1GHz TMS320C6678 chip.
