相位补偿技术在和差单脉冲雷达中的应用

Application of Phase Compensation in Sum-difference Mono-pulse Radar

介绍了比幅单脉冲测角工作原理,分析了和差通道的幅度相位一致性,特别是相位对测角的影响,给出了不同相位补偿在雷达上应用后对目标探测的影响实例。在和差通道中进行一定的相位补偿,再通过一定的幅度较正,能够得到较为理想的目标探测精度。该技术在实践中已经得到了充分的验证,可以在相似的系统中加以应用。

The principle of the amplitude mono-pulse angle measurement is introduced in this paper and the amplitude-phase consistency of sum and difference channels,especially the impact of the phase in angle measurement is analyzed. Influence instances of different phase compensation for target detection are listed. Phase compensation is conducted in sum and difference channels,and then through a certain amplitude correction,and ideal target detection accuracy can be obtained. The technique has been fully validated in practice,and it can be applied in similar system.
