GPS在机载雷达测速精度鉴定中的应用

GPS Application in the Radar Working on Plane Measuring Velocity Precision Appraisement

论述了利用GPS来鉴定机载雷达的测速精度,推导了雷达对目标径向的速度基准值计算公式及其精度计算公式,并计算了该速度基准值及其精度,结果表明:能够满足速度基准值精度要求。强调了在做测速精度鉴定方案时,需要计算在被鉴定速度方向上的速度基准值精度是否满足要求。

This paper treats that appraises measuring velocity precision of the radar working on Plane by GPS, it demonstrates calculating formula and precision calculating formula on velocity reference value from radar to object direction. The paper calculates velocity reference value and its precision, the result shows that can satisfy the demand of velocity reference value precision. The paper emphasizes that need to calculate if velocity reference value precision satisfies the demand along appraised velocity direction when we design the project measuring velocity precision appraisement.
