Correlative Detection of Pulse-Compression Radar Signal Based on Polarization Coding

针对相参雷达体制,提出了基于极化和相位编码的雷达信号相关检测方法。它是在用二相编码完成脉冲压缩的基础上,利用极化编码实现相关检测。该方法不但提高了雷达的检测性能,而且由于采用了新型的极化编码技术,可以提高雷达的抗干扰能力。在介绍极化编码及相关检测原理的基础上,利用理想编码信号和实际数据进行了计算机仿真,仿真结果证明了此方法的有效性。

The method of correlative detection of radar signal based on polarization coding and phase coding for the coherent radar is proposed in this paper. Phase coding is firstly used for pulse compression, then correlative detection is performed by polarization coding. The method can improve not only the detection performance but also the antijamming ability of radar thank to the new polarization coding technique. On the basis of the principle of polarization coding and correlative detection, computer simulation is done for the ideal coded signal and real data, the results prove the effectiveness of the method.
