Abstract: This paper firstly proposes the multipul-target telemetring scheme using DS/CDMA system on the basis of the requirement of the system ,then detailedly presents the operating principle and the key technology of the multipul-target telemetring system .In addition ,the block diagram of the system is shown .The capability of simultaneous measuring parameters of multipul-target is characteristic of the system , and the capability of anti-interference of the system isstronger than that of systems using FDMA or TDMA technology .Furthermore ,it can combine with the GPS technology to complete the tasks of telemetring and telecontrol simultaneously. In a word , the scheme of the multipul-target telemetring system is economical and practicable.
