| 摘 要： | 相位编码信号雷达因为其抗干扰能力以及低截获概率特性而得到了广泛的应用。提出一种新的相位编码信号检测算法，实现了对相位编码信号的特征提取，根据频率构造正弦信号，利用相参检波实现二相编码信号的解码。该算法在信噪比为0 dB时仍然可以对编码信号进行准确的调制特征分析。

| Abstract: | The radar with phase coded signal is widely applied because its anti-jamming capability and low probability intercept(LPI) characteristic are perfect.This paper puts forward a kind of new detection algorithm for the phase coded signal,which realizes the characteristic extraction of the phase coded signal,forms the sine signal according to the frequency,realizes the decoding of two-phase coded signal by coherent detection.The algorithm can exactly analyzes the modulation characteristic of the coded signal wh... |
