在光学和雷达的一系列实际应用中,要求从定位系统的运动载体上测量动目标的坐标。在这种情况下,定位系统在跟踪目标的过程中要对目标和载体相互位移的诸参数进行计算,而后将定位结果与载体本身的座标系联系起来。但是在这种条件下,定位系统载体的运动恰恰是造成目标跟踪及其坐标计算误差的原因之一。在估计了目标空间预测位置的条件下要合理地控制雷达天线,以减少误差,而目标坐标的预测和计算本身当利用与地面相对应的坐标系时是很方便的。
In a series of practical applications of optics and radar, it is required that the coordinates of the moving target be measured from the moving carrier of the positioning system. In this case, the positioning system calculates the parameters of mutual displacement of the target and the carrier during the tracking of the target, and then connects the positioning result with the coordinate system of the carrier itself. However, under such conditions, the movement of the positioning system carrier is precisely one of the reasons for the error of the target tracking and its coordinates calculation. The radar antenna should be properly controlled under the condition of estimating the prediction space of the target space to reduce the error. However, the prediction and calculation of the target coordinate itself is very convenient when using the coordinate system corresponding to the ground.
