Abstract
A simple. light-weight pulse-radar altimeter package has been 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 20km-have been measured accurately over Lake Michigan using a peak power of one watt.
