| 摘要: |
| 多站被动定位中，虚假定位点的识别问题是电子侦察中尚待解决的一个重要问题。本文研究包含一个运动站的只测角两站被动定位系统，提出先用扩展 Kalman 滤波对多个辐射源精确定位，然后通过空间相关处理识别虚假定位点的方法，大量的计算机仿真结果表明，上述识别方法在两目标张角大于测角误差的均方根值时，具有良好的识别效果。系统识别出的真实定位点，其定位精度可达单目标环境下的同等定位精度。 |

| Abstract: |
| Recognition of ghosts is a very important problem in multi-sited passive location system based on bearing-Only measurements. In this paper, the discussion is based on a passive location system which contains a fixed sensor and a moving sensor. A new method for ghost recognition is presented. The approach consists of two phases: the first step is to locate the multi-emitter precisely using extended Kalman filter，Secondly recognizing the ghost with space correlation processing. Computer simulations show that the above recognition method has good performance when angle span between two targets is larger than the standard derivation of angle measurements. The accuracy of true target location by this system in multi-emitter condition approaches to the same value as in single emitter condition. |
