摘要
在目标跟踪领域,优化调度雷达波形能有效提高系统跟踪性能,但现有的方法均局限于单目标情况下的场景。针对多目标跟踪时的雷达波形调度问题展开了研究,首先给出了波形参数与观测误差协方差的关系,介绍了交互多模跟踪滤波算法,然后提出以滤波协方差矩阵的行列式作为对目标跟踪性能的度量标准,并从观测目标选择和波形参数优化两方面对波形调度问题进行了分析,最后结合IMM跟踪算法提出了多目标情况下雷达波形的最优调度方法。仿真实验验证了该方法的有效性。
In the domain of target tracking, optimal waveform scheduling can effectively improve the tracking performance, but the existing methods are all about single-target scenarios. In this paper, optimal waveform scheduling problem in multi-target tracking scenario is researched. Firstly, the relationship between waveform parameters and observation error is presented, and IMM filter algorithm is introduced; Then covariance matrix＇s determinant is used as the tracking performance criterion. The waveform scheduling problem is analyzed from two aspects：the choice of observing target and optimal waveform parameters. Finally, a method for radar waveform scheduling is proposed for multi-target tracking based on IMM algorithm. The effectiveness of this method is testified by simulation results.
