摘要
距离-多普勒(R-D)定位法是利用卫星星历数据和雷达回波数据的距离-多普勒信息对SAR图像目标进行定位,因无须在视场中选参考点,这对月面目标定位具有重要意义。距离-多普勒定位法对地面目标的定位已有广泛的应用,并有较好的精度,本文通过对定位误差源的分析和仿真,得出了距离-多普勒定位法对月面目标定位的精度。
The R-D method utilizes the spacecraft ephemeris data and Range-Doppler frequency information of the SAR echo data to produce an estimatign of the target position.This method performs ground positioning with high precision,and will be very useful to the lunar targets positlening because of independence of reference points.The precision of the lunar targets positioning is calculated after analysing location error rand simulating.
