【摘要】：在端射天線組陣中,由于天線單元間的復(fù)雜互耦,端射天線小間距組陣時(shí)副瓣電平抬高得不到預(yù)期增益的提高,通過拉大單元間距可以抑制互耦、獲得高增益,但又導(dǎo)致出現(xiàn)柵瓣電平.基于此,提出一種基于平板端射天線內(nèi)插虛擬陣元的新型組陣方法——數(shù)字虛擬端射組陣方法,并對(duì)側(cè)向組陣時(shí)該方法的數(shù)字波束合成結(jié)果與實(shí)際端射天線陣的三維電磁仿真軟件(CST)仿真結(jié)果進(jìn)行對(duì)比分析,最后,通過實(shí)驗(yàn)測(cè)試驗(yàn)證了該方法對(duì)于抑制端射天線陣柵瓣的有效性.
[Abstract]:Because of the complex mutual coupling between antenna elements, the sidelobe level elevation can not be improved in the antenna array with small spacing, and the mutual coupling can be restrained by enlarging the cell spacing, and the high gain can be obtained. But it leads to the gate lobe level. Based on this, a new array method, digital virtual end-emitter array, is proposed, which is based on the interpolation of virtual array elements. The results of digital beam synthesis in the lateral array are compared with the results of the 3D electromagnetic simulation software (CST) of the actual end-launched antenna array. Finally, The experimental results show that the proposed method is effective for the suppression of terminal antenna array gate lobes.
