摘　　要：目前国内的多目标测控体制采用的是码分多址来区分多目标,这种体制对PN码的自相关性和互相关性提出了很高的要求。针对多目标测控体制采用的码分多址方式存在的问题,提出了一种指令信息识别多目标的方法,并分析了指令信息识别多目标的可行性,证明了该方法相对码分多址具有简化上行链路、减少PN码的数量等优点。这种方法实现简单,适应性强,对目前的测控体制是一种很好的改进,能很好地适应未来多星测控的要求。Current multi -object TT＆C system in China adopts code division multiple access （CDMA） to distinguish between multi - objects, and strict requirement for PN code autocorrelation and cross correlation is needed in such a system. In view of the problems existing in using CDMA in multi - object TT＆C system, a target identification approach based on using information is proposed , the feasibility of target identi- fication based on using information is analysed, which proves that the method has such advantages as simplifying the uplink, reducing the number of PN code compared with CDMA. This method is easy to be real- ized, has high suitability, and is a good improvement for TT＆C system, so it can meet the demands of future multi - object TT＆C systems.
