Error Estimation and Performance Analysis of the Distributed Satellite Formation for Moving Target Detection
分布式卫星编队的误差校正方法及运动目标检测性能分析

The baseline error and gain and phase error of satellites have a great influence on the clutter cancellation and moving target relocation.As for the measurement of satellite baselines,only an order of decimeter precision can be obtained just by instruments.Fortunately,the error can be estimated and corrected by signal processing.In this paper,a new estimation method is proposed.The performance of moving target detection by space-time adaptive processing is analyzed on the basis of the precision offered by this estimation method.Finally,its validity is illustrated through computer simulations.
