摘　　要：针对传统雷达情报传输方式灵活性、机动性差或受地理环境和通信距离限制较大的现状,在分析散射通信的原理和特点以及散射传输可行性的基础上,提出一种基于散射通信的雷达情报传输系统方案设计.该方案采用具有较好抗干扰能力的扩频通信技术,通过对流层散射传输信息,系统能够在复杂地形或特殊场合的雷达站和旅团情报中心之间实现超视距无线传输.仿真结果表明系统的误码率小于10 3.该设计在战时可作为一种重要的雷达情报应急传输方式和备份手段.On account of the poor flexibility and mobility of the conventional radar intelligence transmission systems or their larger limitation to geographical environment and communication distance, a scheme design of radar intelligence transmission system based on scatter communications is presented in this paper, on the basis of analyzing the principles and characteristics of scatter communication as well as the feasibility of scatter transmission. By using the spread spectrum communication technique that has better anti-jamming ability, the system transmits radar intelligence through troposphere scattering, and can achieve the beyond-the-horizon wireless transmission of intelligence between radar stations and brigade and/or regiment intelligence centers which are located in the complex terrain or special circumstances. Simulation results show that the system has better performance of bit-error-rate, less than 10-3, and it can be used as an important emergency and/or back-up modes of radar intelligence transmission during wartime.
