Analysis on Random Binary Phase Coded Interpulse Modulated Radar Signal

本文推导了随机二相码脉间调制脉冲串雷达信号的平均模糊函数，并给出了计算机仿真结果及其分析。结果表明：该信号的模糊图为“梳齿形”，通过适当选择波形参数，可使该信号在距离和速度上同时具有良好的分辨能力和测量精度。同时该信号的随机性使它具有良好的抗干扰性能。另外，该信号的产生和处理相对于其它随机雷达信号简单，具有良好的工程可实现性。

In this paper, the average ambiguity function of random binary phase coded interpulse modulated pulse sequence is derived, the simulating result and its analysis are presented also. It is shown that its ambiguity view is of “comb” shape. Good resolution and high precision on both distance and velocity can be obtained by selecting suitable wave form parameters. In addition, its anti interference is good because of its randomness. And it is practical because it is easier to be generated and processed than other random radar signal.
