本文提出了UAT机载信号源的生成方法以及硬件实现,设计出小体积、便于携带的UAT机载信号发生装置。通过分析UAT机载信息的编码和传输处理方式,设计PC机的模拟系统软件。根据模拟软件设置不同的参数和不同的模拟方式,从多角度验证UAT地面站的性能指标、报文处理的完好性等,方便维护人员在没有机载UAT设备的情况下验证地面站系统的工作情况,加快查找故障的速度。同时该信号发生装置也能作为UAT地面监视系统软硬件开发的实验室测试仪器。
In this paper, the generation method and hardware implementation of UAT airborne signal source are proposed, and the UAT airborne signal generator with small size and portability is designed. By analyzing the encoding and transmission of UAT airborne information, the simulation system software of PC is designed. According to the simulation software setting different parameters and different simulation methods, verify the performance index of UAT ground station and the integrity of the message processing from multiple perspectives so as to facilitate the maintenance personnel to verify the operation of the ground station system without the airborne UAT equipment Situation, speed up troubleshooting. At the same time, the signal generator can also be used as a laboratory test instrument developed by software and hardware of UAT ground monitoring system.
