摘　　要：航天遥测系统中,不断增长的遥测需求与有限的频谱资源已成为一对亟待解决的矛盾。针对此问题,对国内外遥测体制、遥测频段的现状和发展趋势进行探讨。首先,介绍IRIG标准推荐的调制体制和无线通信新技术的遥测应用情况。其次,结合世界无线电大会的遥测频段分配结果,介绍国外C频段遥测技术的发展。最后,探讨我国的航天遥测调制体制和遥测频段的现状及未来发展趋势。Aiming at the conflict between the increasing telemetry capability requirement and the limited spectrum, which aer- ospace telemetry systems are confronting with, modulation methods and the telemetry spectrum have been discussed. The modulation methods recommended in IRIG Standard and some wireless communication techniques used in aerospace telemetry are introduced. Then the developments of C-band telemetry abroad have been introduced, according to the telemetry spectrum allocation in World Radio Communication Conference. Finally, the development trends of both modulation methods and aerospace telemetry spectrum in China have been discussed.
