摘要
针对对地目标搜索跟踪雷达的单波束探测特点,给出了在只有目标的距离和方位角量测时,快速估算被跟踪目标高度的方法,并在此基础上引入了平面直角坐标系下滤波的方法;视线坐标系是机载雷达系统中跟踪精度较高的一种坐标系,可以在没有高度信息的情况下对目标进行跟踪,本文引用这种坐标系,并引入了径向速度量测,通过仿真结果对两种滤波算法进行了对比。
An algorithm to estimate the target altitude was proposed in this paper.It focused on the characterization that only azimuth angle and range distance obtained in measurements due to the single beam in the ground target searching and tracking radar.Based on this,the filter algorithm was given in the Cartesian coordinate system.The eyesight coor- dinate system was a coordinate with higher tracking precision in airborne radar which can tracking target without azi- muth angle.It was introduced in this paper and the radial velocity wad added.At last,the simulation results of these two algorithms were given.
