本文介绍11位巴克码最小峰值旁瓣滤波器(LP滤波器)的计算结果,LP滤波器长度为39时,峰值旁瓣电平降到-34.4db,比匹配滤波器改善13.6dB。文中还给出滤波器权值误差对旁瓣电平影响的估算公式。
This paper presents the calculation results of the 11-bit Barker minimum peak sidelobe filter (LP filter). When the LP filter length is 39, the peak sidelobe level is reduced to -34.4db, which is 13.6dB better than the matched filter. The paper also gives the estimation formula of the influence of filter weight error on the sidelobe level.
