摘要
在单通道单脉冲自跟踪系统的基础上,说明了交叉耦合产生的原因,讨论了导致交叉耦合恶化的各种因素及解决方法,分析目前存在的几种相位校正方法的局限性,从工程应用的角度提出一种新的相位自动校正方案。该方案对天线平台的稳定性没有要求,校相过程中无需对准卫星,同时还可以实现跟踪接收机的自检,快速实现故障定位。试验表明,该方案校相精度高,适用范围广,具有很高的应用价值。
Based on the Single Channel Monopulse self-tracking system, this paper analyses the reasons of cross-coupling, and discusses all factors and solutions of the cross-coupling deterioration. By analyzing the limitations of several existing phase calibration methods, a new method of phase automatic calibration is put forward for engineering application in this paper. This method can be used to perform phase calibration without pointing to satellite and the stability of antenna platform, moreover, it can make a self-test and a fast fault diagnosis of tracking receiver. The test results prove that the new method has high phase calibration precision and wide application in engineering.
