EFFECT OF INTERCHANNEL MISMATCH ON THE SIDELOBE LEVEL OF A DBF ARRAY
通道响应失配对DBF天线旁瓣电平的影响

This paper discusses the effect of impulse response aberration between channels on the sidelobe level of a DBF array, and then derives the relationship between the frequency response mismatch and the impulse response aberration of a channel, by which the effect of frequency response mismatch between channels on the antenna sidelobe level is acquired. It shows that frequency response mismatch degrades sidelobe considerablely. Finally, the results by computer simulations are demonstrated.
