Lateral channel migration, channel lobe switching, but also volcanic pulses generated a predominantly fining-upward high-frequency cyclicity. 水道的侧向迁移、水道舌状体的转换以及火山脉动产生了主要为向上变细的高频率旋回。
The monopulse concept first appeared in the 1940s. It is a technique for precise tracking, developed basing on two other tracking techniques, conical scan and lobe switching. 单脉冲概念的提出和单脉冲雷达的开发最早开始于20世纪40年代,它是在扫描和波束转换技术基础上发展起来的,用于精密跟踪的一种雷达技术。
