摘要
介绍了基于多径效应的微波着陆系统,分析了测角误差,提出了一种有效降低多径条件下机载接收机的测角误差的数字信号处理方法。该方法主要对误差源的处理及扫描波束波形畸变进行处理,并给出了验证结果,证明了方案的可行性。
This paper introduces the microwave landing system based on multi-path effect,analyzes the angle measuring error,brings forward a digital signal processing method that can effectively reduce the angle measuring error of airborne receiver under the multi-path condition.The proposed method mainly processes the error source and the waveform aberration of scanning beam,and gives the verification result,which proves that the feasibility of the project.
