栅瓣 meaning in Chinese
[电磁] grating lobe
◇栅瓣级数 grating-lobe series; 栅瓣图 grating-lobe diagram
Examples
- First , it was taken that a discuss about the effects of geometry parameters of each piezocrystal on direction parameters ( main lobe width , side lobe amplitude , elimination of grating lobes ) , amplitude of ultrasonic pressure , element viberation pattern , mutual radiation among elements , efficient test regions , ability to keep accurate and near - field distance and so on . based on the direction of ultrasonic field in ulpa deduced by ourselves . in addition , on the base of integrating all kinds of factors , it was put forward that the principle and method for optimized design of geometry parameters of piezocrystals in ulpa transducer , and its design programme and interface were compiled
首先在推导超声相控线阵换能器声场的指向性的基础上，就各个晶片几何参数对指向性指标(主瓣宽度、旁瓣幅度、消除栅瓣) 、声压幅值、阵元振动模式、阵元间互辐射、有效检测区域、精确控制能力、近场长度等方面的影响进行了论述，并在综合各方面影响的基础上，提出了晶片几何参数优化设计的原则和方法，编写了设计程序和界面。 - And the gist of dividing subarray is proposed . according to the gist , a new subarray whose configuration is simple is proposed , and makes its grating lobes unobvious and its adapted antenna pattern close to that of the full optimum processing by confusing the periodicity of subarry and making the power of output noise equal
然后在此基础上提出了一种新的结构简单的子阵结构,并且通过打乱子阵排列的周期性以及保证各子阵输出噪声功率相等,该子阵的栅瓣效应几乎可以忽略且其自适应方向图保形良好。
