多目标的搜索、成像、跟踪、测控与通信

Searching,imaging,tracking,TTC and communication for multitarget

本文讨论了以下技术:空中多目标搜索与成像,给出了一种基于闪光照相原理设计的微波成像系统。这一系统经济、实用,采用的DOA算法先进;空中多目标的精密跟踪,提出了2种基于天线阵和数据处理的跟踪系统:一种是梯度跟踪系统,另一种是单脉冲系统。它们都是在基带用数据处理的办法产生角误差信息,都具有同时跟踪多目标的能力。本文着重讨论了2种系统的跟踪模块的设计与算法,给出了多目标跟踪的仿真结果;多目标测控与通信,给出了基于数字波束形成DBF及数字匹配滤波器—码分多址(DMF-CDMA)技术的多飞行器测控系统。仿真证明本文提出的方法与系统是可行的。

In this paper, the following techniques are discussed： Firstly, the searching and imaging techniques for muhitarget are discussed. A kind of microwave imaging system based on the principle of flashing photography is given. Secondly, the precise tracking techniques for multitarget are discussed. Two kinds of tracking systems based on antenna array and data processing are given, one is the gradient tracking system; another is the monopulse tracking system. Both of them are tracking systems with the ability of multitarget tracking. Finally, TFC （ tracking telemetering ＆ command） and communication system for muhitarget based on DBF （digital beam forming） and DMF-CDMA （digital matched filter-code divide multiple access ） techniques are discussed. Simulations demonstrate that the methods and systems given in this paper are feasible.
