摘要
根据光电雷达测量到的目标方位信息,运用自适应修正增益扩展卡尔曼滤波理论,可以估计出空中目标相对载机的位置和速度参数。文章首先推导了坐标系的转换矩阵,建立数学模型后推导对应的自适应修正增益扩展卡尔曼滤波方程,通过对所得的算法进行仿真验证,表明该算法具有较好的实用性,能够满足载机对目标参数被动探测的要求。
According to information provided by the electro-optic radar, one can obtain the position and speed of the targets relative to the carrier aircraft by using Adaptive Modified Gain Extended Kalman Filter （AMGEKF） theory.. The authors deduced the transform matrix between three coordinates and built up the mathematical models, then presented the AMGEKF equation. The results of simulations showed the good adaptability of the algorithm, which is suitable for passive measurement of target parameters by the carrier aircraft.
