基于方位和多普勒频移的目标机动检测方法研究

摘要

Between two linear motions by changing its course or velocity,the target is assumed at some random instant to switch. On the basis of target bearings and doppler shift information measured by passive observation, elements calculating model based on the orientation and dopper shift is established, the proposed reciprocal maneuver detecting model gets the detection time depend on the characteristics of tracking a target and the results of elements calculating Large amount of emulations are studied, and validate the method what is availability.%研究目标在机动前后均做匀速直线运动,在某一时刻做折线机动的机动目标跟踪检测问题.根据被动观测器测得目标方位和多普勒频移信息,结合方位、多普勒频移测量条件下目标跟踪的特点,建立了基于方位和多普勒频移的要素解算模型,提出了基于要素解算结果的机动检测方法,给出了机动时刻的估计算法,并进行了仿真计算,验证了此方法的有效性.
