口径天线在远场区的冲激响应的含义和适用范围兼评也谈口径天线辐射场的瞬态特性
THE IMPLICATION AND THE APPLICABLE REGION OF THE IMPULSE RESPONSE OF APERTURE ANTENNAS IN THE FAR-FIELD REGIONCONCURRENT COMMENT ON SOME POINTS ON IMPULSE RESPONSE OF APERTURE ANTENNA

摘要: 本文阐明了在使用口径天线在远场区的冲激响应的概念时,远场区是对激励天线的实际信号而言,并非对为求冲激响应而施加在天线上的函数而言;远场区的冲激响应在距离上的适用范围决定于激励信号的频率范围。

Abstract: In this paper, it is clarified that as the term, the impulse response of aperture antennas in the f ar-field region, is used, the far-field region is referred to the actual signal exciting an antenna, not to the Dirac delta function exerted on an antenna for deducing the impulse respose, and that the applicable distance range of the impulse response in the far-field region is determined by the frequency range of the exciting signal. -
