Technique of Doppler compensation for phasecoded signal pulse compression

摘要

Codes used in phase-coded pulse compression waveforms suffer from Doppler mismatch. Based on an analysis of the effects of Doppler mismatch on quariphase-coded waveforms and the performance results, a new technique of Doppler compensation is proposed. This technique solves the problem of the sensitivity of phase-coded signal to Doppler. It is proved that pulse compression performance is quite well by using this technique, and it meets the project's requirement very well.
