摘要
本文介绍一种L频段安控系统 ,它由“三站一中心”组成 ,用三站无线接力的方法来提高覆盖范围并解决地球曲率对通视的限制。系统中采用宽波束、前向纠错、新的L频段、综合基带、大的功率裕量、远程透明监控等措施提高了系统的安全可靠性 ,系统具有优良的性能。
An L-band safety remote control system is introduced which is composed of three stations and one center in order to increase coverage and overcome the limit of earth curvature to intervisibility. In the system such measures as wide beam, forward error correction, new L-band, integrated baseband, large power tolerance and remote transparent monitoring are adopted, so the reliability of system is improved and the system has excellent performance.
