(一)、引言大功率固态发射机的研制和应用已使得雷达向着高可靠性、高稳定性以及减轻重量、缩小体积、降低成本方向迈出了可喜的步伐。国外一般中小功率(例如1千瓦以下)源几乎已全固态化了。同时,大型相控阵雷达的大功率发射机也已成功地被固态组件所置换(如美国雷声公司研制的A N/FPS-115)。国内,不少单位已经把功率晶体管作为有源器件来产生和放大微波能量。通讯、电台和电视等使用固态化发射机日趋广泛。然而,雷达全固态化的关键之一——分布式固态发射组件仍然处于研制阶段。这主
(A) Introduction The development and application of high-power solid-state transmitters have made the radar a welcome step toward high reliability, high stability, weight reduction, volume reduction and cost reduction. Foreign medium and small power (for example, below 1 kilowatts) source almost completely solidified. At the same time, large-scale phased-array radar transmitters have also been successfully replaced by solid-state components (such as American Raytheon developed A N / FPS-115). Domestic, many units have power transistors as active devices to generate and amplify microwave energy. The use of solid-state transmitters for communications, radio and television is becoming more widespread. However, one of the keys to the full solid-state radar - distributed solid-state launcher is still in the development stage. This Lord
