| 摘 要： | 为了提高雷达系统对抗电子干扰的能力,提出了一种新型相参极化捷变雷达信号.通过采用正交极化天线系统,雷达接收机可以首先获取目标的空间和极化信息,然后基于全极化捷变雷达体制,实现对目标的多极化照射,最后对接收到的信号进行极化信息处理、目标检测和跟踪.讨论了具体的信号处理算法,并给出了一种极化捷变条件下的双平面角跟踪方法.仿真实验结果表明:极化信息的引入改善了雷达系统的性能.

| Abstract: | In order to enhance the anti-jamming ability of a radar system,a new signal form used in coherent polarization agility radar is proposed.The space and polarization information of the target are obtained by using the orthogonal polarization antenna system.Based on the complete polarization agility radar system,the concerned target is irradiated by multiple polarization waves and the polarization information processing is done for the received signals to detect and track the target.The specific algorithm of s... |
