| 摘 要： | 高脉冲重复频率(HPRF)雷达目标跟踪需要解决距离模糊问题。本文通过把脉冲间隔数和脉冲间隔变化量作为目标的离散状态,目标的距离和径向速度作为目标的连续状态,将HPRF雷达的跟踪和解距离模糊问题转换为贝叶斯框架下的混合估计问题并且利用粒子滤波方法实现。仿真结果表明本文方法在脉冲间隔数变化时仍可以正确地解距离模糊,并且跟踪精度比多假设方法高。

| Abstract: | The problem of simultaneous range ambiguity resolving and tracking for high pulse repetition frequency(HPRF) radar is considered.The pulse interval number(PIN) and its incremental variable are taken as discrete components of the target states and the target states such as target range and radial velocity are considered as continuous components.Thus,the simultaneous range ambiguity resolving and tracking problem is transformed into a hybrid estimation problem in a Bayesian framework and solved by a particle ... |
