摘要
分析了线阵在超宽带冲激信号激励下的辐射特性,给出了这一信号体制的线阵辐射特性的表征方法,提出了用非等间距非等幅激励线阵代替等间距等幅激励线阵提高方位向分辨率压低旁瓣的方法,并进行了仿真实验。
The radiation characteristics and expression method of linear- array under the excitation of ultra- wide band （UWB） impulse signal are analyzed in this paper. Through detailed analysis, it is shown that the azimuth resolution can be enhanced through adjusting the weight coefficients of the elements and the spaces between the elements of the linear - array without altering the array length. Finally, the result of the simulation is presented.
