面向相控阵应用的具有特定功率分布多端口磁控管单元实验验证
Experimental Demonstration of Multiport Magnetron Units with Specific Power Distribution toward Phased Array Applications
摘要
Abstract
In this paper,three magnetrons with each of them having specifically designed multiple coupling ports,which deliver specific power distribution for developing a magnetron array based on efficient phase locking between them,are proposed to produce high power ms-level pulses.To demonstrate the effectiveness of the mag-netron with one and two coupling ports as a unit for efficient phase locking,we designed experimentally the cou-pling ports delivering～10%(the power distribution ratio)of the output power of the magnetron for coupling with other magnetron units.The effect of one and two coupling ports on the operating capability,including the power distribution ratio,anode current and frequency,is demonstrated by establishing an equivalent experimental model which can characterize an ideal operation of the array.The experimental results show that the power distri-bution ratio is～9%for the magnetron with one coupling port,and～12.5%(coupling port 1,2)for the magne-tron with two coupling ports.This shows good uniformity of the coupling capability of the two coupling ports and provides guidance for optimizing the power distribution ratio of multiport magnetron units,which are critical for efficient phase locking in the proposed array in future and higher power arrays.关键词
