摘要
针对依靠红外传感器提供目标角测量,以雷达间断工作提供目标距离测量的目标状态估计问题,从探测精度的要求出发,提出了一种基于由直角坐标系和修正极坐标系组成的混合坐标系的扩展卡尔曼滤波算法,在一具体战术环境进行了数字仿真,并对仿真曲线进行了分析。
In target state estimation,the angle of target is provided by infrared sensor and the distance is provided by discontinous working of radar.Based on the requirement to detecting precision,an extended Kalman filter algorithm is provided using hybrid coordinates composed of the Cartesian and Modified Polar Systems.Simulation was carried out in actual tactical environment,and the results were analyzed.
