Research on Verification Algorithm Of Velocity Measurement Accuracy for Airborne Radar

为了验证机载雷达探测雷达目标时所得到数据的精度,文中在分析84坐标系和地理坐标系转换关系的基础上,介绍了坐标系之间的转换矩阵,并通过计算目标机GPS所测得的目标机速度与载机雷达所测得的目标机速度的偏差,实现了机载雷达测速精度的验证算法。

To verify data accuracy which airborne radar measures velocity of target air,this paper researchs the conversion matrixs among the coordinates based on the analysis on relation between 84 coordinates and NED(North East Down)coordinates.We realize the verifying algorithm of data accuracy which Airborne Radar measures velocity of target air through calculating the difference between the target air velocity from GPS on the target air and the target air velocity from airborne radar.
