研究了雷达跟踪时的采样间隔和功率自适应设计问题。依据交互多模型跟踪算法和协方差控制的方法,提出了目 标跟踪时自适应采样间隔的设计方法。该方法对所跟踪的目标设定期望跟踪精度,从采样间隔序列中选择符合期望精度 的采样间隔,使得采样间隔最大化;在恒定检测概率的前提下,根据目标远近、雷达散射截面积大小,给出了辐射功率的自 适应控制方法。仿真结果证明了文中方法的有效性。

Adaptive design of sampling interval and power is studied in this paper. A novel method of adaptive sampling interval design is proposed based on interacting multiple models (IMM) tracking algorithm and covariance control method. Desired tracking accuracy is set for every target firstly, and then the algorithm selects the largest sampling interval from the interval sequence. On the condition of constant detection probability, an adaptive method for emitting power is given based on target distance and radar cross section(RCS). The simulation results show that the method is effective.
