随机二相码脉冲压缩雷达信号分析

Analysis of Random Binary Phase-Coded Pulse Radar Signal

本文首次给出了随机二相码脉冲压缩雷达信号的数学模型及其平均模糊函数，进而对该平均模糊函数进行了分析，最后通过计算机仿真结果表明，该雷达信号具有近似＂图钉＂型的平均模糊函数，具有良好的无模糊测速、测距性能和抗干扰能力．

In this paper,the mathematical model and the AAF of random binary phase-coded pulse radar signal are presented for the first time.Both the expression analysis and computer simulation show that the AAF is approximate to 'thumbtack' form. and the signal of this kind can be used to measure the distance and velocity unambiguously, and the signal has good ability of counter-countermeasure.
