| 摘 要： | 宽带比相单脉冲雷达要求天线幅度、相位特性完全对称,否则将会对角误差测量结果造成一定影响。推导了天线幅度、相位不对称对宽带比相单脉冲测量目标角误差的影响公式。分析了天线幅度、相位不对称对测量角误差的影响性质,可为提出天线设计的对称精度要求提供参考,并提出了天线幅度、相位不对称的补偿方法。

| Abstract: | Wide-band phase comparison radar requires that antennas be completely symmetrical,other wise have some angle measurement error.According to the basic principles of using wide-band phase comparison mono-pulse measuring angle,the influence of antenna's dissymmetry in angle measurement is analyzed.The result of simulation can provide reference to antenna designing.A method is given to compensate the dissymmetry. |
