摘　　要：针对航天测控技术发展中对多目标测控技术的需求,提出了采用特殊信息编码算法解决多目标测控中的问题。该算法采用与常用的扩频码分多址体制不同的编码方法和解算方法,可依靠现有的测控设备,应用扩频自适应反馈滤波算法,有效完成对多目标的测控任务,并可成功解决多用户冲突问题。给出了新型扩频自适应反馈滤波算法的编解码原理,通过分析计算验证了该算法的有效性。To the demand of multi-object trace technology in the developing TT＆C（tele-tracking ＆ controlling） system,a special algorithm for information code in TT＆C system is put forward to solve the problems in multi-object trace system. The algorithm adopts the different coding and decoding way from the spread-spectrum CDMA（code division multiple access）system, it can use the existing TT＆C equipment, to solve the task of multi-object trace,and the jam of many users working at the same time by means of the spread-spectrum adaptive feedback filtering algorithm. The elements of new spread-spectrum adaptive feedback filtering algorithm are proposed and the calculating results verify the algorithm＇s availability.
