针对单脉冲火控雷达角度测量过程中的相位变化问题,分析了振幅和差单脉冲雷达角度处理过程以及产生接收通道相位变化的因素。结合工程实践,给出了某型宽带雷达部件参数改变引起相位输出实测数据。此外,介绍了减小测距误差的数据纠正方法。最后,提出了接收通道相位一致性补偿方法。通过模拟仿真,对比通道相位差对雷达测角特性曲线的影响,仿真结果表明,10°的相位不平衡对定向特性曲线影响很小,能够满足系统的设计要求。

To solve the problem of phase change during angle measurement for monopulse fire control radar,the angle measurement of sum and difference patterns of amplitude monopulse radar and the factors caused phase change are analyzed.Based on the engineering application,the tested phase output data due to the changes of the parameters of components in a broad band radar are also presented.Further more,the er-ror correction method used to reduce the range errors is introduced.Lastly,a redeeming method for the con-sistency of receiving channels is proposed.The contrastive analysis of the impact of the phase difference on the curve of angle measurement is made.The simulation results show that the 10°of phase inconsistency has little influence on the directional characteristic curve,which meets the design requirement.
