Research On Signal Processing In Microwave Landing System Receiver

This article mainly deals with the method of processing the received signals of the time-base scanning beam microwave landing system,design and implement simulation of generating and receiving signals on simulation platform.Test the parameters of the simulation results,analyze simulation performance based on test results,also introduce the time difference extraction algorithm.This article first introduce the research status and development trend of microwave landing systems and the working principles,key technologies,signal formats,and theoretical basis of the angle measurement principle of the microwave landing system.Then simulate the signal and test its accuracy on VS2010 and matlab mixed programming platform.Based on a comprehensive analysis of the signal,a signal processing scheme for the system receiver is proposed,analyze the process diagram and introduce the key technologies used,and simulate the receiving scheme on VS2010.Then test data on the receive side and send side,and the rationality and accuracy of the receiving scheme are evaluated.Then the system's time difference extraction algorithm is introduced.Then introduce the microwave landing system host computer design on labwindows/CVI platform.Then simulate the signal and test its accuracy on ISE and Modelsim.After that,data testing is conducted using the host computer and hardware sending and receiving equipment,and the test data is analyzed to verify the correctness of signal generation and reception.
