本文介绍用于某多卜勒雷达的微带天线阵设计,该雷达是一种固态连续波雷达,采用调频测频体制,工作在X波段,用于测量超低速的运动目标,该机的许多元器件如固态源、混频器等均已集成,但天线仍沿用喇叭天线,相形之下颇不相称,如用微带天线取而代之,则该机基本可实现集成化. 所谓微带天线即在双面铜箔板的一面用光刻技术制上所需要的图案而成,如图1所示.它不但结构轻 This article describes the microstrip antenna array design for a Doppler radar, a solid-state continuous-wave radar that uses a frequency-modulated frequency-measuring system that operates in the X-band to measure ultra-low speed moving targets. Many of the aircraft Components such as solid-state sources, mixers, etc. have been integrated, but the antenna is still followed by the horn antenna, the contrast is quite disproportionate, such as the use of microstrip antenna instead, the aircraft can be basically integrated. One side of the double-sided copper foil with lithography technology required to make the pattern, as shown in Figure 1. Not only its light structure
