摘要 |
由于方位向采样不均匀.已有的频域算法如CS算法(Chirp Scali 成像,提出了一种可用于方位向不均匀采样多子阵合成孔径声纳的CS成像算法。统等间隔布阵和匀速直线运动的特点。将方位向不均匀采样的傅立叶变换分解为以利用FFI.提高计算效率。成像结果及分析表明,此方法可以很好应用于CS算法快速高效的特点。 |
摘要_英文 |
Because of non-uniform sampling on azimuth direction,the standard frequency hnang algorithm like CS Call’t be directly applied to multiple-receiver synthetic apertureimaging. A multiple-receiver synthetic aperturesonar imaging CS algorithm is brought out The algorithm makes use of two characteristics of multiple-receiver synthetic aperture system,that is,equidistant deployment of physical element arrays and uniforln velocity.Based on that,the azimuth direction non-uniform Fourier transform is divided into several uniformFourier transforms. which can use FFT.hnagiIIg Result shows that the method Call be applied to multiple-receiver synthetic aperture hnaging and maintains the high computing efficiency of standard CS algorithm. |
