摘要
Abstract
An equivalent baseband method in frequency domain is proposed to analyze the characteristics of short pulses radiated by the reflector antenna with large diameter, and the baseband waveform reconstruction method of the radiation field is derived theoretically.Taking the antenna with the diameter of 4.5 m in Ku-band as an example, the baseband waveforms of the main lobe, the direction of the 3 dB antenna beam, and the first to the third side lobes are reconstructed by the proposed method.It is found that the radiation waveforms of the main lobe and the direction 3 dB beam are in good agreement with those of the radiation source, while the radiation waveforms of the first to the third side lobes show a slight distorted.关键词
