雷达对抗侦察系统对运动目标的单站无源定位

Single Observer Passive Location of Radar Counterreconnaissance System for Moving Targets

实现对运动目标辐射源的单站无源定位是对新体制雷达对抗侦察系统的基本要求。文中在现有研究的基础上,提出了一种利用波达方向、相位差变化率、载波频率及多普勒频率变化率的单站无源定位方法,结合一种地面雷达对抗侦察系统,分析了其定位原理、测距误差和可观测性,最后给出了单次测距的计算机仿真结果和结论。

It is an elementary requirement to a new type radar counterreeonnaissance system that realizing single observer passive location for moving targets. Based on existing research, a single observer passive location method is proposed by using direct of ar- rival, phase difference rate-of-change, frequency and Doppler frequency rate-of-change in this paper. Associating with a certain fixed radar system, it analyzed location theory, ranging error and observabihty. In the end of the paper, it gives computer emulation of single measurement and a conclusion
