摘要：
The waveform ill the radiation field of a radar antenna call be obtained by using the convolution of the transmitted signal and the antenna far-field impulse response (AFFIR). In this paper, the finite difference time-domain (FDTD) method is applied to calculate the AFFIR of an X-band 54-element waveguide slot array at different radiation angles using the excitation of a wideband Gaussian pulse. To demonstrate the usage of the far-field impulse response, the waveforms in the radiation field of a narrowband Gaussian pulse are calculated at three different radiation angles by the convolution of the pulse and the waveguide slot-array AFFIR.
