摘要: 根据和差单脉冲雷达接收机原理,设计了一款基于和差波束比幅比相的S波段跟踪接收机。该接收机主要由和波束接收支路、方位差波束接收支路和俯仰差波束接收支路组成,每个接收支路分别完成对信号的放大、滤波、混频和自动电平调整。两路差波束信号再以和波束信号作为比较基准,通过相位和幅度的比较得出角度信息。详细分析了如何实现支路之间的相位比较和幅度比较,并利用比幅信息和比相信息实现对目标的自动跟踪。经过验证系统的各项指标符合设计要求。

Abstract: According to the theory of mono-pulse radar receiver, designing a type of band-S receiver based on gain and phase detect. The receiver includes sum-beam link、azimuth angle-beam link and pitching angle-beam link. These receiver links managed the signal amplifying、filtering、mixing and AGC function. Analyzing how to detect gain and phase between three receiver links and how to automatic follow according to the information of amplitude and phase. All the system performance is validated to be according with design requirement.

Key words: mono-pulse, AGC, gain detect, phase detect
