中文摘要：
提出了一种新的处理双根号形式斜距历程的方法。该方法通过泰勒级数展开将收发分置和非停走停引起的畸变项分离开来,通过对相位驻留点的近似,将多子阵合成孔径声纳二维频域表示为类收发合置项和收发分置畸变项的乘积,并通过多子阵数据融合的方法对收发分置畸变项进行补偿,最后利用经典Chirp-scaling算法实现了多子阵合成孔径声纳图像的重建。该方法原理清晰易懂,实现简单,效率较高。仿真计算证明了其有效性。
英文摘要：
A novel method is proposed to deal with the double square root slant range. This method can separate the distortion resulting from the multiple receivers and non Stop-and-Hop through Taylor series expansion. And the wavenumber domain function for multiple receiver SAS is expressed as a product of the monostatic item and the rnultistatic distorted item. The latter is compensated for by means of multiple receiver data fusion. Finally, the classic chirp-scaling algorithm is used for the ima- ging reconstruction of multiple receiver SAS. The simulation results prove the proposed method to be effective.
