双通道跟踪接收机的动态极化校相
|
摘要
传统校相方法无法检测双通道单脉冲体制雷达极化失配问题。采用基于静态目标的动态极化校相方法,即在静态条件下,增加一个信标天线正交极化角校相环节,用于完成跟踪接收机和差信道的校相工作。数学模型的构建、仿真计算以及实测结果均表明,采用该方法可以准确识别双通道单脉冲体制雷达双通道极化失配问题,弥补了传统校相方法在检测跟踪接收机和差信道极化失配问题上的缺陷。
The traditional phase calibration method cannot detect the double-channel monopulse radar polarization mismatch problem. The dynamic polarization phase calibration method based on the static target,which is under the static condition,adds a beacon antenna orthogonal polarization angle phase correction link to complete the sum and difference channel's synchronous phase calibration of dual-channel tracking receiver. Construction of mathematical model,simulation and experimental results show that this method can accurately identify dual-channel monopulse radar's dual-channel polarization mismatch problem,make up defect of the traditional method phase calibration for detecting tracking receiver's sum and difference channel's polarization mismatch problem.
