近几年来,随着固体技术和自动数据处理技术的发展,雷达技术又有了新的进展。在发射机方面由于采用了脉冲压缩和其它综合技术获得了高分辨力,在某些波段上还使用了全固态放大器。在天线方面,相控阵已广泛应用,旁瓣电平大为改进。自适应技术不断取得新成绩。数字处理的采用,使接收机和信号处理都得到了重大改进。分述如下: 一、相控陣丹麦的“眼镜蛇”是最新型的相控阵雷达,这种雷达的天线阵面,为了减小角旁瓣,有源阵元按提供锥体形空间扫描的方式配置。移相
In recent years, with the development of solid technology and automatic data processing technology, radar technology has made new progress. High resolution is achieved at the transmitter due to the use of pulse compression and other synthesis techniques, and all-solid-state amplifiers are also used in some bands. In the antenna, the phased array has been widely used, side lobe level greatly improved. Adaptive technology continues to make new achievements. The adoption of digital processing has led to significant improvements in both receiver and signal processing. As follows: First, the phased array Denmark's “Cobra” is the latest type of phased array radar, the radar antenna array, in order to reduce the angle sidelobes, the active array according to provide cone-shaped spatial scanning Configuration.
