对消比,cancellation ratio
1)cancellation ratio对消比
1.Upper limit ofcancellation ratio of sidelobe canceller旁瓣对消系统的对消比上限分析
2.First of all,the effect of target signal on the performance of sidelobe canceller by comparing with ideal sidelobe canceller is analyzed in the paper,and the expression of weights vector andcancellation ratio is deduced.讨论了理想情况下的旁瓣对消系统,分析了目标信号效应对旁瓣对消系统性能的影响,推导出了考虑目标信号效应时的权值和对消比的表达式,并以只有一个辅助通道的旁瓣对消系统为例,推导得到:目标信号对旁瓣对消系统性能的影响程度主要取决于辅助通道收到的目标信号强度,目标信号越强,目标信号效应的影响越明显。
paring with FIR LMS the wavelet based adaptive canceller can obtain highcancellation ratio and fast convergence only with small number of adjustment weights.用基于Ｈａｒｒ小波变换的自适应滤波器对具有不同冲激响应的实际声回授系统进行辨识，在自适应回声对消器中可以只用少量的权达到足够大的对消比，该方法运算量小，收敛快，适用于对实际声回波对消问题的解决。
2)CR (Clutter Cancellation Ration)杂波对消比
3)Double contrast radiography of the upper gastrointestinal tract上消化道双重对比造影
4)logarithmic ratio of aerosol backscatter-to-extinction后向散射消光对数比
1.In the process of inversion, selection of thelogarithmic ratio of aerosol backscatter-to-extinction has a large effect on extinction coefficient.使用Mie散射激光雷达在阴、雾和晴三种天气状况下采集了大气回波信号,从所测数据反演气溶胶消光系数的过程中发现,气溶胶后向散射消光对数比对反演结果存在较大影响。
5)Logarithmic ratio of aerosol backscatter extinction后向消光对数比k
6)cancellation[英][,k?ns?"le??n][美]["k?ns?"le??n]对消
1.As most of non-coherent radar on active duty has no or little cluttercancellation ability,whenever flying targets enter the area of ground clutter,it is very difficult for radar to observe targets.由于大多数非相参体制雷达没有杂波对消能力或杂波对消能力较差,一旦各类飞行目标进入地杂波区,雷达就难于观测目标。

对消法分子式：CAS号：性质：又称对消法。一种测量电动势的方法。用一个外加可调的电势与待测电池电动势对抗，当调节至电路上无电流通过时，则两电势恰好对消(或称得到补偿)，此时的外加电势值即为所测电池的电动势。这是一种精确测量电势的常用方法。利用补偿法设计的仪器称电位差计。
