临近空间高速飞行器测控需要解决“黑障”、超视距时空连续覆盖和多目标等难题，根据太赫兹电磁波可以穿透等离子体而大气传输损耗大的特点，研究以飞机和飞艇为主要平台的空基太赫兹测控系统，提出采用扩频体制实现对高速飞行器进行测距、测速、遥测和遥控的综合测控以及多目标测控，采用 nRR(n≥3)测量体制实现高速飞行器的外弹道测量，分析表明空基太赫兹扩频测控系统技术可行，但离工程应用还有较大差距。

Tracking Telemetry and Command(TT&C) for near space hypersonic spacecraft needs to solve blackout,over-the-horizon and multi-target problems. According to the characteristics that Terahertz waves can penetrate the plasma and are attenuated intensively in the atmosphere,the Terahertz TT&C system based on airborne platform including aeroplane and airship is researched. The Terahertz system can accomplish integrated function of velocity measurement,ranging,telemetry and telecommand by using spread spectrum technology;and tracking telemetry and command for multi-target can be realized as well. The ballistic measurement of hypersonic spacecraft can be implemented by using nRR(n≥3) method. The analysis results indicate that the technology solutions for air-borne Terahertz spread spectrum TT&C system are reasonable,while there are significant differences for engineering application.
