摘要
Abstract
In the process that the monopulse sum-difference beam is used to track and measure the target in phased array radar,when the tracking beam is far away from the azimuth and elevation normal,the sum-difference beam will be widened and distorted in the array coordinate system,which will seriously affect the accuracy of angle measure-ment.In order to solve this problem,an improved monopulse sum-difference angle measurement method for phased array tracking radar is proposed in this paper.Using the characteristic that the beam of phased array radar does not change with the scanning angle in the sinusoidal space coordinate system,the target deviation is obtained by the sum-difference angle measurement in the sinusoidal space coordinate system,and the position of the target in the array coordi-nate is obtained by coordinate transformation combined with the beam direction in the sinusoidal space coordinate sys-tem.The effectiveness of the method is verified by simulation.关键词
