摘　　要：针对机载单站无源定位这一多维非线性滤波问题,提出一种将相位差变化率和多普勒频率变化率相结合的复合定位方法。通过讨论该方法的定位原理,并进行单次定位误差分析,得到影响定位精度的主要因素。仿真结果表明,该定位方法比相位差变化率法和多普勒频率变化率法具有更好的适用性和实时性。In order to solve the problem of single airborne passive location of multi-dimensional nonlinear filtering,a composite positioning method of combining phase difference change rate and Doppler frequency change rate was proposed.Through positioning principle discussion and single error analysis,the main factors influencing positioning accuracy were got.The simulation results show that the improved positioning method has better applicability and real-time than the phase difference change rate method and the Doppler frequency change rate method.
