Design And Implementation Of Microwave Landing Analog Signal Generation And Reception

Microwave landing system is a more advanced navigation system in ground navigation.Like other precision approach landing systems,the microwave landing system provides the necessary guidance information for the aircraft to be landed to ensure the safe landing of the aircraft every time.In various landing systems,microwave landing system has its own unique advantages.It has the advantages of high reliability,anti-interference,scalable new featrues.ect.This article mainly studied the design and implementation of generation and reception of microwave landing analog signal.Firstly,this paper briefly introduced the microwave landing system research status at home and abroad,its future development trend and the research purpose and meaning.Secondly,this paper introduced the key technology of microwave landing system and the format of various signals.Thirdly,using the VS2010 and Matlab software platform designed analog signal of microwave landing system.Basic guidance signals,data words and MLS all cycle signals are generated.MLS all cycle signals were analyzed and studied.And the AZ signal’s recognition and processing were studied at the receiving end.Next,the host computer of microwave landing system was designed with Labwindows/CVI software.The host computer was divided into two parts,one was the design of basic guidance signals and MLS all cycle signals,the other part was the design of basic data and auxiliary data word.Finally,the hardware simulation of the microwave landing analog signal was realized.The basic guidance signals,data words and MLS all cycle signals were generated on the hardware development platform.The generated signal was simulated with Modelsim software,and the MLS all cycle signals was analyzed emphatically.All signals generated by the system were connected with the receiver,and the test data was given and the test data was analyzed to verify the correctness of the signals.
