摘要: |
无源被动定位技术中一个重要问题, 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(DOA)的定位方法, 由于可观测性的要求, 在单观测平台对运动目标定位时, 常常需要观测平台作特殊的机动运动, 这种约束给实际操作带来很大不便。本文提出了一种引入测频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。运用该定位法定位, 观测平台的运动形式可以任意, 特别有意义的是, 在满足某些条件情况下观测平台还可以完全静止不动。 |

Abstract: |
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 information and frequency information obtained from electromagnetic radiation. the observability analysis is given too. Using this method, the special maneuver of observer is no longer necessary, which is necessary for traditional measurements such as DOA only. |
Keywords: passive location, DOA, frequency, observability, pseudo-linear filter |
