摘要:

介绍了对线性调频信号进行脉冲压缩及其旁瓣抑制的方法,分析了多普勒频移对结果的影响,并对脉压后信号主副瓣比,幅度和脉宽的变化进行了分析。仿真结果表明,脉冲压缩能在雷达发射功率受限时,提高目标的探测距离,并保持较高的分辨率。

Abstract:

Pulse compression(PC) is one of the most important technology of radar signal processing.The article first introduces the methods of LFM pulse compression and sideband suppression,then presents the simulation results,and finally analyses the effect of Doppler shifting on results,the RMS and the transform of signal magnitude and bandwidth after pulse compression.Simulation indicates that pulse compression can increase the target detection range while retaining good resolution when the radar transmission power is limited.

Key words: pulse compression;LFM;Matlab
