一种新的HPRF目标跟踪算法

A New Target Tracking Algorithm for HPRF Mode

高重复频率(HPRF)在脉冲多普勒雷达上应用正日益广泛,距离高度模糊是其面临的难题之一。文中提出了一种新的HPRF目标跟踪算法,利用距离参数化和概率数据关联算法,能快速得到目标距离的模糊倍数,该方法的特点是不需要调频测距,在波形调度上类似于中重复频率,从而降低了雷达设计难度,简化了数据处理流程,在工程中有较好的应用前景。本文最后还进行了大量的数据仿真,验证了该算法的技术可行性和有效性。

High pulse refrenquency（HPRF） is widely used in pulse-Doppler radars, whose range ambiguities is severe and difficult to resolve. In this paper, we propose a new target tracking algorithm for this problem is propsed, which can get accurate target range quickly without frequency modulation by utilizing range parameterized and probabilistie data association techniques. The method can be applied with the similar way like MPRF, and then reduces complexity of radar as well as its data processing. So the proposed method has good prospects in practical engineering applications. As demonstrated by many numerical simulations, the method is both feasible and effective.
