摘要
提出了一种基于概率理论的移动双站到达频差(FDOA)方法对地面干扰源进行定位。两接收机在被干扰区域上空运动时往往能两次(或多次)接收到地面干扰源的信号,获得两个(或多个)到达频率差。该方法利用到达频差和在接收到信号时接收机的位置、速度及信号频率等数据给出辐射源的位置估计。采用的概率算法不需求解高次非线性方程组,仅需求解三元一次线性方程组。计算机仿真实验表明,利用该方法可以实现高精度的地面干扰源定位。
A frequency-difference-of-arrival （FDOA） location method of mobile bi-station based on probability theory is proposed. The ground signal always are received twice （or more times） by the two receivers from the jammer on the ground as they traverse the jammed region and there are two （or more） FDOAs. Position estimation of jammer is relied on the FDOAs, the positions and velocities of the two receivers and frequency of the signal. In the probability algorithm, one order linear equations should be solved without high order nonlinear equations. It is proved by computer simulations that this jammer location method is effective.
