摘要
为减少作战飞机目标跟踪过程中的雷达辐射,提出了一种ESM间歇量测情况下的机载雷达/ESM协同跟踪与辐射控制方法。采用基于IMM-EKF的雷达/ESM序贯滤波算法对目标进行滤波跟踪,利用跟踪过程中的预测协方差与预定门限进行比较控制雷达辐射,并给出了不同ESM间歇时间、控制门限与雷达辐射时间的关系。研究结论有助于提升作战飞机的隐蔽性和生存能力。
To reduce the radar radiation of warfare airplane during target tracking, an airborne radar/ ESM synergistic tracking and radiation control method with intermission ESM measurement is proposed. A radar/ESM fusion method based on IMM and sequence filter is used to track target by using the comparison between the predicted error covariance and the given threshold to decide the radar to radiate. Then, the relationship between the radar radiation times with different ESM intermission times and thresholds is presented. The research conclusion may help increase warfare airplane＇ s concealment and survival capacity.
