摘　　要：针对数字阵列雷达(DAR)系统中,白噪声和阵元通道幅相不一致对数字单脉冲测角性能影响大小的问题,给出了基于数字波束形成的相位和差与幅度和差单脉冲测角原理.通过仿真验证了白噪声和阵元通道幅相误差对两种测角方法性能的影响,并与实际系统的测量结果进行了比较.该研究对工程实现有一定的参考价值.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.
