Study Of Algorithm For Phased Array Monopulse Angle Measurement

In communications systems,phased array antenna with broad application prospects and good value,in order to ensure smooth communication between systems,communication equipment need to determine the relative location of the target,in order to accurately track the target location,high precision of angle measurement is very important.Introduced a phased array monopulse angle measurement method,first leads to monopulse angle measurement technology of theoretical knowledge and phased array(linear array and area array)antennas formed the basic principle of respectively on linear and rectangular array and simulation analysis of the differential angular.Then through and poor beam get corresponds to of angle sensitive function,using sine space transform features,for variable substitution,will single pulse angle sensitive function in antenna array surface coordinate system in the with scan angle of nonlinear changes features change for sine space in the simple translation of linear transform features,get angle sensitive function and errors signal of mathematics relationship,eventually seeking out target where of azimuth angle and pitching angle,and through theory data simulation on the method for has validation.Finally,combined with the phased array monopulse angle measurement items,given the measured data using MATLAB graphics simulation further to verify the feasibility of the method.
