摘　　要：由于仪表着陆系统(ILS)在使用中存在的局限性,微波着陆系统(MLS)能为任意起降飞机提供连续、精确的3维坐标信息、不受气候条件的限制,使得它在民航领域中产生了重要的应用价值。文中介绍了微波着陆系统的工作原理及相应信号处理系统的实现方案,并详细论述了基于DSP实现的DPSK自适应解调理论和硬件方案,为微波着陆信号处理提供了新的途径。Due to the limitations of ILS in application and the fact that MLS can provide continuous, precise three-dimensional coordinate information for aircraft taking off and landing without being restricted by weather, MLS is of great value in the field of civil aviation. This paper introduces the principle of the micro-wave landing system and the realization of the corresponding signal processing system. It also describes the DSP-based adaptive DPSK demodulation algorithm and hardware design and proposes a new approach to micro- wave landing signal processing.
