摘　　要：针对传统的机载测向交叉定位收敛速度慢、定位精度低的问题,探讨了基于变化率测量的机载单站无源定位技术,分析了不同模型下测多普勒变化率、测角测相位差变化率和仅测相位差变化率无源定位的算法原理、性能和特点,对多普勒变化率、相位差和相位差变化率这些定位参数的测量和提取方法进行了说明,为变化率无源定位系统的设计和应用提供了理论依据。According to the problems that the convergence rate of traditional airborne direction-finding cross-localization is slow and the localization precision is low,this article discusses the airborne single station passive localization technology based on the change rate measurement,analyzes the arithmetic principle,performance and features of passive localization using measurement of Doppler change rate,angle and phase difference change rate and only phase difference change rate in the different models,explains the measurement and extraction method of localization parameters such as Doppler change rate,phase difference and phase difference change rate,provides the theory base for the design and application of the passive localization system based on the change rate.
