Abstract: It is important to calibrate the system errors of precise-measurement radar for the aim of ensuring its measurement precision. The satellite calibration method for radar system error is a new method by measuring optical tracking satellites. In this paper, the key algorithm of satellite calibration method based on least-square estimation is analyzed and deduced. Then, the satellite calibration system is designed. Finally, the algorithm is simulated, according to the value of radar system error parameter obtained with traditional calibration method, and the simulation results are analyzed. It shows that the satellite calibration technique based on least-square estimation method is effective.
