摘要构建了一种便携式，铅笔，脉冲，多普勒，3厘米波长雷达，以研究各种各样的气象现象，包括龙卷风，严重的风暴和边界层过程。 ，具有完整的扫描功能，实时显示和归档，并安装在卡车上，以便便携性和完全的移动性。罕见的气象现象。雷达采用新的高功率，基于PC的数字中间频率（IF）数据采集方案，称为PIRAQ。风暴已用于检测尘埃和其他边界层结构。
Abstract A portable, pencil-beam, pulsed, Doppler, 3-cm wavelength radar has been constructed to study a wide variety of meteorological phenomena including tornadoes, severe storms, and boundary layer processes. The new radar, the Doppler on Wheels (DOW), has full scanning capability, a real-time display and archiving, and is mounted on a truck for easy portability and full mobility. This portability allows the radar to be brought to within a kilometer of rare meteorological phenomena. At this range, the pencil beam of the radar is very narrow, permitting significantly higher-resolution measurements (at 3-km range, 64 m × 64 m × 75 m) than are usually possible with stationary or airborne systems. The radar employs a new high-powered, PC-based, digital intermediate frequency (IF) data acquisition scheme called the PIRAQ. The radar has successfully collected data in several tornadoes and tornadic storms and has been used to detect dust devils and other boundary layer structures. The sensitivity and mobility...
