摘要:

文中基于单个观测站观测所得的方位角和多普勒频率信息,在建立了状态转移矩阵和观测矩阵的基础上,通过最小二乘法,对辐射源进行无源定位。从仿真结果可知,基于方位角和多普勒频率的单站无源定位技术是可行的,且多普勒频率测量噪声标准差对均方根误差的影响相比方位角测量噪声标准差明显。

关键词: 最小二乘法, 无源定位, 多普勒频率

Abstract:

This article is based on the azimuth and Doppler frequency received from a single observatory.It establishes the state transition matrix and the observation matrix.Then it uses the least square method for the passive location of emitter.Simulation results show that the single station passive location technology based on the azimuth and Doppler frequency is feasible.And the influence on the root mean square error from Doppler frequency measurement noise standard deviation is more obvious than that from the azimuth measurement noise standard deviation.

Key words: least square method;passive location;doppler frequency
