摘要
新研制成功的遥测、遥控、外测三合一的统一测控系统，在有镜面反射条件下，对于超低空飞行目标，能克服多径效应衰落的影响，稳定地进行捕获跟踪测量，并且具有很高的可靠性。它也可在其他使用场合推广。文章介绍了工作原理、技术特点以及如何克服低仰角多径效应衰落和达到高可靠性所采取的措施。系统可灵活配套使用，以适应多种使用条件。在空用应答机上，解决了强弱信号共用信道的问题，减小了体积，降低了频率综合器相位噪音。
This paper has introduced a new chinese TT&C system. This system includes telemetry, remote control, orbit measurement sub-systems. It has passed Reception Appraisal Meeting and got higher level appraisal. It can be used under mirror reflection enviroment condition to overcome the multipath fading effect of low height flight target and can stable capture & track target with high reliability. It also (cont. on p. 93) (cont. from p. 66) may be used for other conditions. This paper has introduced the principle of operation with the brief block diagrams. It introduces the technical features which includes the methods to overcome the multipath fading, the methods to get high reliability. This system is very flexible and may be suitable to other enviroment conditions. On the target there is a transponder. This transponder has overcome the difficulty of high level and low level signals transmitting over the same channel. This transponder has used many technologies to reduce diamension and it has overcome the low phase noise problem of crystal. This system has used new open feature telemetry system. In this paper has given important data of transmission channel. At the end of this paper it has given: the end user test result, the appraisal of the Receiption Appraisal Meeting. This system is the highest level system of the same kind low angle receiving system in China.
