跟踪制导雷达交叉极化测角误差分析
|
摘要
交叉极化引起的测角误差会降低跟踪制导雷达制导精度。本文提出利用天线空域极化分析交叉极化导弹测角误差,完善跟踪制导雷达制导精度分析,给出减小该误差的设计原则。通过试验验证,该方法分析正确、设计原则有效可行。
Guidance precision of tracking and guidance radar will be impacted due to angle measuring error caused by cross polarization. For purpose of improving guidance accuracy of tracking and guidance radar,angle measurement error of missile is analyzed by using spatial polarization of antenna,and design principle for reducing error is given. Test results verified that the method is correct and the design principle is effective and feasible.
