摘要
跨平台航迹精度测评对多平台协同使用传感器航迹数据具有指导意义,论文介绍了相对于本平台距离/方位的测评方法(方法一)和空间距离精度的测评方法(方法二),从非线性坐标变换的角度分析了本平台位置对测评结果的影响,其中方法一的计算结果在两平台位置相差不大的情况下主要受被探测目标相对于这两个平台的方位角度差影响,方法二的计算结果则不受本平台位置的影响,因而后者更有意义。
The evaluation of cross-platform tracking accuracy has guiding significance in cooperatively using multiplatform sensors tracking data. The measurement method using distance/azimuth to the base platform to evaluate the tracking accuracy（Method one） and the other method using space distance to evaluate the tracking accuracy（Method two） are intro- duced, and the influence of platform position on the evaluation result in the perspective of nonlinear coordinate transform is analyzed. The evaluation result of method one is mainly affected by the difference of the azimuth and angle when two platforms were in a certain area, the evaluation result of method two is not affected by the platform position.
