摘　　要：微波着陆系统(MLS)是目前较为先进的地基着陆引导系统,它具有比仪表着陆系统(ILS)更加完善的引导功能,可以更好地满足现代航空的精密着陆引导需求。简要介绍了MLS的系统组成和接收机测角单元的信号处理流程,提出了一种MLS中频数字化接收机载波同步的改进方案,并对其性能进行了仿真验证。MLS is an advanced land-based landing guidance system in recent time. Compared with the ILS, it can better meet the requirements of modern aviation because of its more perfect guide function. The composition and the digital signal processing of the angel measuring unit are briefly described in this paper. After that, an improved carrier synchronization program in the IF digital receiver is put forward, and its performance is evaluated by simulation.
