Abstract :
In digital array radar (DAR) system, digital mono-pulse techniques with digital beam forming method are widely used recently. Firstly, this paper introduces the theory of amplitude-comparison of sum and difference lobes and phase and sum-difference digital mono-pulse. Secondly, noise and element amplitude and phase errors which affect the accuracy of angle measurement are analysed and simulated. Lastly, the simulation results and measurements are compared and some proposals for engineering are given.
