Regardless of scanning method selection,beam-offset angle measurement often existed during searching process for phased array radar seeker.Due to the basic principle of radar angle measurement,the angle measure-ment error was larger if the beam-offset occurred,resulting in a large pointing deviation of the beam,which has a certain probability to lead to capture failure.To address this issue,a method was introduced based on beam point-ing correction which can effectively improve the capture probability of phased array seeker.It was verified through digital simulation analysis that the angle capture probability of the seeker can be effectively improved by using the modified beam pointing to capture the target.
