ratio of sidelobe to mainlobe副主瓣比
1.Finally, several group of chaotic binary-phased codes which have the optimum ratio of sidelobe to mainlobe are screened out by performing the operation of self-correlation.并用MATLAB编制的程序获取均匀分布的混沌序列,经自相关运算后从中筛选出若干组具有最佳副主瓣比的混沌二相码。
3)mainlobe peak to sidelobe peak ratio主副瓣比
1.Compared with entire correlation digital pulse compression,time delay characteristic,compression ratio,the mainlobe peak to sidelobe peak ratio and the width of the mainlobe peak of partial correlation digital compression are analyzed.文中对LFM信号在部分相关情况下的数字脉冲压缩进行了理论推导,并将其与完全相关数字脉压的情况进行对比,分析了时延特性、压缩比、主副瓣比和主瓣宽度等压缩性能参数。
4)peak sidelobe ratio峰值主副比
5)maximum relative side lobe level最大副/主瓣比
