摘要
论述多普勒频率差无源定位技术的实现方法 ,对等多普勒定位曲线误差进行分析 ,利用LMF(Levenberg -Marquardt-Fletcher)算法求解辐射源位置。在三运动平台条件下 ,通过计算机仿真 (按照MonteCarlo方法 )对算法的定位精度和性能作了评估。
The passive location of electromagnetic emitters is an indispensable important method in the Electronic War(EW) .The realization of passive location using the difference of doppler frequency is discussed. The error of the isodops location curves is analysed and the calculating formulas of the emitter location are acquired by the LMF algorithm.The performance of this algorithm is evaluated by computer simulation (according to Monte Carlo methods) for three locomotive panels.
