摘要
针对无线电高度表的辐射时机控制问题,研究基于多测高传感器的协同控制方法。该方法基于信息融合思想,利用序贯卡尔曼滤波对多源高度观测进行信息融合,然后通过间歇控制或状态估计协方差控制来确定高度表的辐射时机。结合实验数据,利用MATLAB对该方法进行仿真,结果表明,协同控制可显著降低无线电高度表的辐射时间,同时使系统保持较高的测高精度。
According to the problem of radar altimeter radiation control, a cooperative control method was presented based on muhi-source height measurement. The method adopts a sequential processing Kalman filter and fuses multi-source altitude observation first, and then uses estimation covariance to determine the radiation timing of altimeter. Simulation results show that coordinated control method significantly reduces the radiation time of radio altimeter while maintains a high measurement precision.
