摘要:
介绍了基于民用广播、电视信号的被动定位系统的发展现状.在此基础上,提出了一种新的解决方案.广播、电视信号被空中的飞行器扰动以后,在接收端形成接收功率的波动.利用这一特点,采用广泛分布的大量廉价的接收天线代替单个的大型天线系统,根据各接收端信号的功率扰动信息和接收天线的位置信息共同对造成信号扰动的目标进行定位.新的方案在达到同样被动定位效果的同时,在系统造价、系统的安全性等方面有较大的改善.
Abstract:
The present situation of passive location systems based on broadcasting and TV signals is briefly introduced. A new solution method is presented. The signal power perturbation on receivers caused by air target as well as the receiver’s position information are used to extract the exact location of the target. Large quantities of less expensive receiving units instead of complex phase array antenna are used to detect the signal power perturbation. Lower system cost as well as higher system reliability are achieved.
