Passive location is the determination of the position of an emitter from the available information obtained from the electromagnetic radiation. It is difficult for traditional measurements such as DOA only to determine the posi- tion of emitter quickly and accurately. How to make use of the available information from electromagnetic radiation is the key to improve the quality of passive location.

Passive location is the determination of the position of an emitter from the available information obtained from the electromagnetic radiation.

无源被动定位是利用从威胁辐射源接收到的辐射信息,对威胁辐射源进行定位的技术。以往的研究,常常局限于利用方向角(DOA)信息。由于定位精度对角度测量误差的敏感性,仅利用DOA信息很难得到迅速准确的位置信息。本文提出了一种利用相位变化率信息进行快速定位的定位方法,并给出了相应的算法和仿真结果,以及与传统只测角定位法的比较。

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.

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。

Technology of passive location has broad prospects in applications. In this paper, the single observer passive location method using phase rate of change is introduced based on existing methods. This new method can obtain the direction of the target with phase information of two orthogonal interferometers on the observer and the radial distance with the corresponding phase rate of change. Then the target can be located with high speed and precision. Some locating expressions are given when the flying posture of the observer is changed. Simulations show that this method is effective.
