异构环境下的多子阵合成孔径 声呐距离多普勒成像算法.

Aiming to solve the low efficiency imaging of multi-array synthetic aperture sonar, this paper proposed a fast imaging method for multi-array synthetic aperture sonar in heterogeneous environment. It considered the range Doppler algorithm characteristic for multi-array synthetic aperture sonar and different calculation features between CPU and GPU, the intensive calculation such as range compression, phase compensation, range cell migration compensation and azimuth compression was implemented on GPU, which greatly enhanced the imaging efficiency for multi-array synthetic aperture sonar. In the end, it verifies the validity and efficiency of the proposed method through the imaging experiment performed on real data and the speedup is up to 14.45 times compared to the serial algorithm.
