In this paper, a PD radar signal is researched, which is modulated by randomly staggered pulse sequence whose phase is also modulated by random binary-phase code.

本文研究了随机脉冲位置调制与脉冲之间随机相位调制相结合的脉冲多卜勒雷达信号。

Present a whitening signal algorithm based on disordering sequence. One bases on chaos sequence, another bases on pseudo random sequence.

给出了基于序列顺序置乱的信号白化算法：混沌序列乱序白化算法和伪随机序列乱序白化算法。

Results Random noise of the signal is depressed and ventricular late potential is enhanced after time sequence adaptive filtering.

结果时序自适应滤波器能有效地降低信号中的随机噪声，滤波后心室晚电位信号得到了相对增强。

Only a receiver programmed with the same random sequence would be able to follow the signal as it hopped from one frequency to another.
