Bias Analysis of Return Signal Simulator Used on Radar Altimeter Calibration
用于雷达高度计定标的海面回波模拟器误差分析

The radar altimeter prelauch calibration was commonly carried our by return signal simulator,so the bias on return signal simulator need to be quantitatively analyzed.The return signal simulator principle,biases such as quadratic phase bias,amplitude and phase bias,delay bias were detailed.In the last section the whole system bias on return signal simulator was calculated.The HY\|2 radar altimeter prelaunch calibration was successfully realized on the basis of return signal simulator precision.
