利用相位变化率对运动辐射源无源定位的研究

Passive Location and Observability Analysis to Moving Target\=with Phase Rate of Change Measurements

无源被动定位技术中的一个重要问题，是如何使定位的约束条件尽可能地少，即尽可能地提高方法的可操作性。只利用测角信息的定位方法，在（单观测平台）对运动目标定位时常常需要观测平台做特殊的机动运动，这种约束使得只利用测角信息的定位方法适用性较差。如果将观测平台获得的相位变化率信息用于定位，则可以减少定位方法的约束条件，为无源被动定位技术的实际应用带来方便。提出一种利用相位变化率信息对运动目标进行定位的定位方法，并给出了可观测性分析。

How to make the method to come true conveniently is very important in passive location.A new method of passive location to moving target is presented in this paper,which makes use of both DOA and PRC(Phase Rate of Change)information obtained from electromagnetic radiation. And the observable analysis is given too.Using the method,the special maneuver of observer is no longer necessary,which is necessary for traditional measurements such as DOA only.
