摘要
本文给出了逆合成孔径雷达系统的幅相特性的补偿方法,指出补偿可分为混频前的系统补偿和混频后的系统补偿。通过微波暗室实验证明,所给补偿方法是正确的。
A method for compensating the amplitude-phase distorfion of ISAR system is described. This system compensation can be separated into two parts; the compensation of the system before mixing and the compensation of the system after mixing. The experimental results of the compensation in microwave dark room are given. It is shown that the method presented is effective.
