针对极化合成孔径雷达由于发射和接收端受通道幅相不平衡、天线串扰、电磁波传播特性和系统噪声等因素影响,从而造成遥感数据不能反映真实目标特性的特点,提出了应用方位对称的随机分布目标和多个三面角反射器回波数据定标系统的方法,给出了应用该方法的具体步骤,并通过此方法对X波段机载SAR系统的实测数据进行了分析,试验结果验证了该方法的可行性和有效性。 Aiming at the characteristics of the polarization synthetic aperture radar that the remote sensing data can not reflect the true target characteristics due to the unbalance of amplitude and phase of the channel, the crosstalk of the antenna, the electromagnetic wave propagation characteristics and the system noise at the transmitting and receiving ends, Distribution targets and multiple triangulation reflector echo data calibration system, the specific steps of the method are given, and the measured data of X-band airborne SAR system are analyzed by this method. The experimental results verify that The feasibility and effectiveness of this method.
