摘要
本文介绍了30MHz声表面波(SAW)13位巴克码匹配滤波器,以及采用最小二乘法(LS)设计的低旁瓣滤波器,分别获得了21.6dB及33dB的主副瓣比。同时还给出了这两种相关器性能随多谱勒频漂变化的实验曲线。
This paper presents 30MHz Barker 13 matched SAW filter and a low sid-elobe SAW filter designed using the least square method, and the ratio of mainlobe and sidelobe is 21.6dB and 33dB resp tively. The performance variation of these two types of correlators with the Doppler It is also given in the paper.
