遥测系统是飞行实验项目测试系统的重要组成部分,依据IRIGB106B标准PCM数据流的FM调频无线传输体制,系统工作于S波段,由于发展变化,飞机各种技术状态的不断升级,同时为了满足未来多款新型飞机测试的需要,通过遥测系统无线下传进行监控的数据量和种类日益增多,遥测系统所承担的压力越显突出,需进行NRZ_L码随机化技术研究。
Telemetry system is an important part of flight test project test system. Based on the FM radio frequency transmission system of IRIGB106B standard PCM data stream, the system works in the S-band. Due to the development and changes, various technical states of the aircraft are constantly upgraded. In order to meet the future requirements The need for new aircraft testing, the amount and type of data being monitored wirelessly through the telemetry system is increasing, and the pressure on the telemetry system becomes more pronounced and randomization of NRZ_L codes is required.
