摘要

A simple, light weight pulse radar altimeter package was designed and tested to accurately measure altitudes of meteorological balloons. This altimeter uses a superregenerative RF stage which is controlled by an adaptive feedback system. Altitudes to 20 km were measured accurately over Lake Michigan using a peak power of one watt.
