机载雷达辅助无源传感器对目标协同跟踪具有重要战术作用,而当前相关算法模型较为简单.为了贴近工程实际,提出一种机载雷达辅助无源传感器对杂波环境下机动目标的跟踪算法.该算法考虑了地球曲率和载机时变姿态等因素的影响,基于地心地固(ECEF)坐标系,联合交互多模型(IMM)和概率数据关联(PDAF)方法,以综合预测协方差的迹为控制变量来管理机载雷达的开关机.仿真结果表明,通过选择合适的控制门限,在节约辐射能量、提升生存能力的同时算法的跟踪性能并无明显下降,从而表明了所提出算法的有效性.
Airborne radar-assisted passive sensors have an important tactical effect on the target cooperative tracking, but the current related algorithm model is relatively simple. In order to be close to the engineering practice, a tracking algorithm for the maneuvering targets in airborne radar is proposed. The algorithm takes into account the influence of earth curvature and time-varying attitude of the carrier, and based on the geocentric solid (ECEF) coordinate system, the joint interaction multiple model (IMM) and the probability data association (PDAF) method to comprehensively predict the covariance trace Which is used to control the on-off of the airborne radar.The simulation results show that the algorithm can save the radiation energy and improve the survivability of the airborne radar without reducing the tracking performance by selecting the appropriate control threshold, which shows the effectiveness of the proposed algorithm Sex.
