双语例句
- The factors which have influence over the null depth and zero point position of two basic microwave antenna difference beams are analyzed theoretically from the point of engineering application.
从工程应用的角度出发，在理论上分析了影响两种基本类型微波天线差波束的零值深度、零点位置等指标的因素。 - Also, decision tables containing null values, which are regardless and hard to deal with at present, are analyzed in depth in order to find useful information.
其次，对人们容易忽略的含噪声决策表的属性约简也进行了分析。 - The improved smooth algorithm based on the characteristic sub-space used deepen the null to fall the depth, enhanced the system's signal to noise ratio.
研究了改进的基于特征子空间的平滑算法，加深了零陷深度，提高了系统的信噪比。 - The antenna array amplitude and phase errors were very big which affect the sidelobe and null depth of radar beam. So it is imperative to calibrate the array antenna under this situation.
高频雷达工作环境十分恶劣，阵列天线的幅相误差较大，破坏了雷达波束的旁瓣和凹口零值深度，为进行杂波干扰抑制，阵列幅相误差校准势在必行。
