雪崩晶体管产生窄脉冲用于探地雷达

Narrow Impulse Using Avalanch Transistor Applied in Ground Penetrating Radar System

雪崩晶体管产生窄脉冲用于探地雷达于东海（东南大学毫米波国家重点实验室，南京２１００１８）近年来，晶体管在雪崩区的运用越来越广泛，采用雪崩效应后，可以很方便地产生具有毫微秒甚至亚毫微秒上升时间以及很大峰值功率的脉冲．由于专用雪崩晶体管的出现，使得实用的...

The principle of avalanch transistor is described.The narrow impulse generator circuit which can balancingly output positive and negative impulses with duration of 1 ns is analysed, designed and test results are given. The circuit is used in 1 GHz ground penetrating radarsystem for static pulse generator. The relationship between them is analysed. The practical results applied to field are shown.
