在很多军用场合，不能得到目标的位置信息，只有目标的角度、角速度和角加速度信息；因此，用纯角度测量估计目标的位置、速度和加速度具有重要意义。文章对解决上述问题的方法进行了综述。将ＭＰＣ中对目标的纯角度测量下的平面跟踪滤波器推广到三维ＭＳＣ，对目标进行三维跟踪，仿真结果表明，该方法是解决三维纯角度测量跟踪问题的有效途径。
In many military applications, the target position information can not be obtained, only the target angle, angular velocity and angular acceleration information; therefore, it is of great significance to measure the position, speed and acceleration of the target by the pure angle measurement. The article summarizes the methods to solve the above problems. This paper extends the planar tracking filter under the pure angular measurement of MPC to the three-dimensional MSC and tracks the target three-dimensionally. The simulation results show that this method is an effective way to solve the tracking problem of the three-dimensional pure angle measurement.
