摘　　要：利用相位差变化率可对目标进行快速测距,在实际使用中,相位差变化率通常利用相位差数据来提取,而相位差数据中包含野值会严重影响着相位差变化率的提取精度。提出了一种利用载机的运动信息来有效剔除野值的方法,并运用仿真结果验证其有效性。The phase difference change rate can be used for rapid ranging to the target,in practical application,the phase difference change rate is often extracted by the phase difference data,but the outliers in the phase difference data will seriously influence the extracting precision of the phase difference change rate.This paper puts forward a method to effectively eliminate outliers by using the motion information of the aircraft,and proves the validity through the simulation result.
