对两种脉压信号的分析和对比研究

Research into The Analysis and Comparison of Two Pulse-compression Signals

脉冲压缩信号有效解决了雷达作用距离与距离分辨力之间的矛盾,因而在各种体制的雷达中获得广泛应用。研究了两种普遍应用的脉压信号——线性调频信号和相位编码信号,从时频特性、脉压过程和模糊函数的角度分析了这两种信号的差异。

The contraction between the radar detection range and range resolution has been effec-tively resolved by pulsecompression（PC）signals,so the PC signals are widely used in various mechanism radars.Two common PC signals——linear frequency modulation signal and phase-coded signal,are studied in this paper,and the differences of two PC signals are analyzed from the aspects of time-frequency domain characteristics,pulse-compression process and ambiguity function.
