摘    要:多接收阵合成孔径声纳成像中,在距离多普勒域作由非停走停近似引起的方位走动的补偿对于窄带多接收阵成像是满足要求的,但对于宽带成像,则会引起很大的系统相位误差,从而造成成像的散焦。指出了窄带系统误差的近似补偿不适用于宽带成像的原因,并随后给出了适用于宽带的多接收阵系统误差的时域补偿方法。

关 键 词:合成孔径声呐  多接收阵  宽带成像  系统误差补偿

Abstract:According to narrow band imaging, the range migration compensation of multiple receiver synthetic aperture so- nar imaging in the range - Doppler domain caused by non stop-and-hop approximation is feasible, but for wideband imaging, a lot of phase error and the defocused imaging are caused. The narrowband system error of the approximate compensation does not apply to wideband imaging, and receiving array system error compensation methods in time domain which are applicable to wideband are given.
Keywords:synthetic aperture sonar  multiple receiver  wideband imaging  system error compensation
