Abstract:

Most of the modern pulse system radars adopt pulse compression technology to resolve the contradiction between range resolution and average power.The engineering realization of the pulse compression technology is shifting from customized hardware to general hardware.The paper expatiates on the basic principle of the digital pulse compression and an engineering realization of the digital pulse compression based on the general hardware,introduces the hardware source and software flow chart of the main IC chips,and verifies the effectiveness of the engineering design method according to a comparison between the simulation results with the practical engineering results.

Key words: pulse compression;DSP;processing in frequency domain;general hardware;matching filter
