main lobe meaning in English
吱瓣
主波束, 主瓣
Examples
- When the signal frequency is 4688hz , the width of the main lobe of the directivity is 28 degrees and the theoretical value is 26 degrees
指向性测试结果显示,最大值方向和第一对最低点宽度与理论值吻合,主瓣宽度实测28度,而理论值为26度。 - At last this paper points out that precision of test can be improved by enhancing reflection level of quiet - zone , and researches the relation of reflection level , precision of test and main lobe of testing radar
最后指出可以通过提高静区静度指标要求到达提高试验精度的目的，并研究了静区指标与被试品主瓣宽度、角模拟精度之间的关系。 - Its angular resolution ability under different snr is summarized comprehensively . the highest resolution of bayesian method is 1 / 18 bandwidth of the beam main lobe i n high snr ( 20db ) and 1 / 3 bandwidth in low snr ( - lodb )
在高信噪比( 20db )下贝叶斯高分辨方位估计方法的角度分辨门限高达1 18波束宽度，低信噪比( - 10db )下也能达到1 3波束宽度。 - From the analysis and simulation , it can be seen that with the method , the detection performance of slowly moving target in the main lobe clutter area will be largely improved with the condition of engineering errors
但于涉动目标检测方法却不存在这种制约条件，且动目标检测性能与dpca最优状态下一致。因此是一种性能比较好的、值得推广应用的慢速目标检测方法。 - Conventional airborne radar clutter suppression techniques utilize the diffrernce in doppler frequency domain between clutter and target returns to suppress clutter . doppler frequency domain one - dimension adaptive filtering , which usually used in main lobe clutter suppression
传统的机载雷达地杂波抑制方法采用多普勒频域一维自适应滤波,即利用杂波和目标信号回波在多普勒频域上的差别对杂波进行抑制。
