摘要
依据自适应副瓣相消的原理 ,着重分析了相对带宽较宽的干扰对副瓣相消性能的影响 ,提出了改善带宽特性的方法 ,进行了仿真验证。改善带宽特性的方法包括增加更多的辅助阵元 ,在阵元后面加入延迟节 ,利用快速傅里叶变换 (FFT)等。
This paper presents the influence of the wider band interference to SLC(sidelobe cancellation) performance, based on adaptive SLC principle. The use of more elements, adding the tapped delay-lines behind the elements and using fast Fourier transform (FFT) processing behind the elements are considered as some methods of improving SLC bandwidth and performance. Also the calculated results and simulations are given.
