中文摘要：
成双线的数组声纳的择向性函数能被用来识别左 / 权利的目标。但是表演由在二根线之间的距离是有限的并且也存在为目标鉴定的盲目区域。一个方法，基于在二个线数组之间的时间延期评价，被建议识别左 / 权利的目标。方法与在二个线数组之间的距离的变化是柔韧的，盲目区域是可观的减少。理论分析结果和认识方法被描述。为精确估计二个线数组的时间延期的插值方法上的一个算法底被导出，因此，左右的歧义问题被解决。
英文摘要：
The directivity function of twin-line array sonar can be used to identify left/right target. But the performance is limited by the distance between two lines and also exists the blind area for target identification. A method, which is based on the time-delay estimation between two line arrays, is proposed to identify left/right target. The method is robust with the variation of distance between two line array, the blind area is considerable decreased. The theoretical analysis results and realization method is described. An algorithm base on interpolation method for precisely estimating time-delay of two line array are derived, therefore the left-right ambiguity problem is solved.
