In this paper, a digital pulse compression system with high performance and high precision is developed by using a general digital signal processor (DSP), and a hardware platform based on TMS32 0 C31, which is a general purpose DSP chip, is established to realize Fourier transform and inverse Fourier transform Transform and adopt the method of fast convolution in frequency domain to realize the pulse compression system.A water treatment structure is proposed, a high performance digital pulse compression system is designed and implemented, and the key problems in the implementation are discussed. The system performance is analyzed, A part of the experimental results have been obtained.It has been achieved by using a common DSP to achieve high-precision, high-performance digital pulse compression system
