Abstract

Abstract

Correction of gain nonuniformity is researched by using taper microstrip. The physical correction model is founded. The taper microstrip compensates the magnitude attenuation by compensating the impedance of microstrip. The taper microstrip is designed. The correction results of curve taper microstrip and straight taper microstrip are compared with each other. The voltage nonuniformity decreases from 15.0% to 1.6% and the gain nonuniformity decreases from 70% to 8% with curve taper microstrip compensation while the frequency of pulse is between 0 and 4 GHz. The taper microstrip with width from 6.00 mm to 4 mm has a good effect of correcting the gain nonuniformity for current framing camera.
