一种TWS雷达天线水平度补偿的设计方法

机-相扫描三坐标雷达的天线和天线所在平台一起做摇摆运动,导致雷达波束指向的不稳定。因此,雷达所在平台水平度将严重地影响雷达的跟踪精度。基于边扫描边跟踪(TWS)系统的三坐标雷达,介绍了一种在雷达数据处理中利用扇区流水处理方式,对信号处理检测点迹进行天线水平度补偿的设计方法,主要包括水平度的获取方式、水平度的补偿方法等。应用结果表明,该方法能有效地提高雷达的测角精度。

A Design Method for Antenna Levelness Compensation in TWS Radar

The antenna of one-dimensional phase scanning 3D radar often sways together with the antenna platform, which leads to the instability of radar beam pointing. Therefore, the levelness of radar platform will seriously affect the tracking accuracy of radar. Based on the 3D radar in track-while-scan (TWS) system, a design method is introduced in this paper, which uses the sector stream processing in radar data processing to compensate the antenna levelness of the signal processing detections, including the levelness acquisition method, the levelness compensation method and so on. The application results show that this method can effectively improve the radar angle measurement accuracy.
