本文根据某连续波雷达的设计要求,从抗杂波干扰性能、抑制泄漏信号能力、多卜勒失配、距离和速度分辨力等方面出发,对各种适合于该雷达的调制信号的性能和可实现性进行了分析,对m-序列码信号和m- 序列模2加钟复合码信号的性能进行了计算机模拟。作出了它们的模糊函数图和Q-函数图。通过对它们性能的比较,为雷达波形的选择提供了理论上的依据。
In this paper, according to the design requirements of a continuous wave radar, from the aspects of anti-clutter interference performance, suppression of leakage signal ability, Doppler mismatch, distance and speed resolving power, the performance of various modulated signals suitable for the radar and The feasibility was analyzed, and the performance of m-sequence code and m-sequence modulo-2 composite code was simulated by computer. Made their fuzzy function graph and Q-function graph. The comparison of their performance provides a theoretical basis for the selection of radar waveforms.
