报道了一种采用雪崩晶体管的大电流辐射器的研制和实验研究。LCR用于辐射持续时间为2ns的非正弦脉冲电磁波。测量了近场和远场的辐射场强。所描述的LCR在5 m的距离处产生约4.2 mA/m的磁场强度，辐射器电流幅度约为0.7 A，上升时间为1 ns。通过场强下降到其峰值的一半来测量的天线方向图的宽度为120/spl deg/。
The development and experimental investigation of a large-current radiator (LCR) with a pulse generator using avalanche transistors is reported. The LCR is intend for radiating nonsinusoidal pulse electromagnetic waves with a duration of 2 ns. The radiated field strengths in both the near and the far field are measured. The LCR described produces magnetic field strengths of about 4.2 mA/m at a distance of 5 m for radiator current amplitudes of about 0.7 A with rise time of 1 ns. The width of the antenna pattern, measured by the drop of the field strength to one half of its peak value is 120/spl deg/.
