swath width meaning in Chinese

地带宽度
割道宽度

A chirp - z transform ( czt ) algorithm on the which is similar to range - doppler algorithm is studied , and the effective swath width is analyzed . secondly , a modified block czt algorithm is presented , which improvs the computational efficiency of the high - resolution sar imaging with wide swath
其次研究了一种与距离-多普勒算法类似的线性调频z变换( czt )算法，分析了有效测绘带宽度的问题；提出了一种改进的分块处理czt算法，提高了对大场景高分辨率sar成像处理的计算效率。
Firstly , in this paper , the basic principles of sar imaging are exploited following the analysis of sar imaging process ; it is shown that the imaging algorithm of traditional sar can be used effectively only on the condition of narrow relative bandwidth signals , narrow azimuthed processing angle and narrow swath width . large range migration has brought many new features and difficulties . after comparing many imaging algorithms , we find out the direction research of the uwb - sar imaging algorithm
本文首先从sar成像的原理出发，分析了sar成像处理过程；指出传统sar的高效成像算法只有在窄信号相对带宽、窄方位向处理角、窄条带宽度的条件下才能有效运用，大距离徙动给大处理角uwb - sar成像带来了许多新的特点和难点，据此分析比较了各种成像算法，找出了适合uwb - sar高效算法研究的基础。
