摘　　要：为了将无人机更好的应用于侦察作战,针对传统的BO定位技术等定位系统,作战区域小,精度低,收敛速度慢等缺点,提出一种适用于无人机的机载单站快速无源定位技术;首先对无人机无源定位系统进行设计,建立计算多普勒频率变化率定位方法的无人机观测平台,提出一种脉冲群多普勒频率变化率的测量方法,最后对定位系统整体进行仿真。In order to improve UAV reconnaissance operations, for the traditional positioning technologies such as BO, small combat zone, low precision, slow convergence and other shortcomings, this paper pres- ented a suitable UAV airborne single station passive location technology. First, UAV passive positioning system was design, and UAV platform calculate Doppler frequency rate of change of the positioning method was built, and then a burst rate of change of Doppler frequency measurement method was presented. Final- ly, we had simulation of the whole positioning system.
