Abstract:

In this paper,linear frequency modulation (LFM) signal,non-linear frequency modulation (NLFM) signal and phase-coded signal are applied in pulse compression radar system.The basic principles and the mathematical model of these three signals are introduced.Based on the MATLAB simulation,the pulse compression effect of the three types of radar pulse compression signals can be compared by analyzing the pulse compression amplitude and the mainlobe-tosidelobe rate with same parameters.

Key words: pulse compress;linear frequency modulation;non linear frequency modulation;phase code
