In view of the problem in a digital array radar system, which is the size of any impact on the performance of digital mono-pulse angle measurement is resulted from the inconsistency of amplitude-phases of white noise and array element channel, this paper presents the principles of mono-pulse angle measurement based on the sum and difference of phase and amplitude formed by digital beams. By simulation, the impacts of amplitude-phase errors of white noise and array element channel on the performance of two methods of angle measurement are verified and comparison with the measured results of the actual system is done, thus providing a certain reference for engineering implementation.
