利用相位变化率对固定辐射源的无源被动定位

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。

Passive Location of Fixed Emitter Using Phase Rate of Change

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. A method of passive location is presented in this paper, which makes use of both DOA information and PRC (Phase Rate of Change) information obtained from electromagnetic radiation. The principle interpretation and derivation of algorithms, and the simulation and performance analysis of algorithms are also presented.
