摘要
该文提出低副瓣有源相控阵天馈系统中的一体化设计方法,从几个主要方面阐述如何进行一体化设计,在2×48元天线阵上试验,实测波瓣的峰值副瓣电平和差波瓣零深均在-31dB以下,当波瓣扫描至±60°时,其峰值副瓣电平不高于-26.5dB,表明一体化设计的必要性。
An integralization design method in the antenna and feed system of active phased array for low side lobe is presented in this paper. From some main rsepects detail how to do the integral design. Some experiments have been done on the 2x48 elements antenna array. The measured peak side lobe level and the zero depth of the difference pattern are all lower than -31dB. When the pattern scan to ?0? the peak side lobe level is not higher than -26.5dB. It is shown that the integralization design is necessary.
