摘要
单站无源定位技术具有广阔应用前景。论述了2种对慢速运动目标的单站无源定位技术,一种是基于相位变化率的方法,需要侦察平台做一定的机动运动,另一种是相位变化率和多普勒频率变化率相结合的方法,侦察平台不需要做额外机动,但增加了对目标信号测量信息的维度。2种方法各有特点,均可在工程中得到应用。
The passive location technology of single station has wide application prospects.This paper discusses two passive location techniques of single station to slow moving targets:one method is based on phase variation rate and needs the reconnaissance platform in maneuvering movement;the other method is based on the combination of Doppler frequency change rate and phase change rate,dosen’t need extra maneuvering movement of the reconnaissance platform,but increases the dimensionality of measurement information for target signal.Both methods have their own characteristics,and can be applied to engineering.
