【摘要】：在传统的声纳系统均采用声压水听器构成阵列模型对目标进行探测跟踪时,由于声压直线阵存在目标"左右舷模糊"问题,为准确估计目标真实方位,分析了包括直线阵、圆阵、十字阵和Y形阵在内的四种常见阵形的常规波束形成方法,并通过仿真比较了不同阵形对声纳目标的跟踪定位性能。结果表明,除直线阵会产生左右舷模糊目标外,其余阵形均可确认目标真实方位,且圆阵效果最好,十字阵效果最差。但直线阵空间增益大,波束宽度窄,在非端射方位区域,探测距离和方位分辨力均优于其它阵形。
[Abstract]:In the traditional sonar system, the acoustic pressure hydrophone is used to form the array model to detect and track the target. Because of the "starboard ambiguity" problem in the sonar linear array, it is necessary to accurately estimate the true orientation of the target. The conventional beamforming methods of four common formations, including linear array, circular array, cross array and Y-shaped array, are analyzed, and the tracking performance of sonar targets with different formations is compared by simulation. With the exception of linear array, the real azimuth of the target can be confirmed, and the effect of circle array is the best, and the effect of cross array is the worst, but the space gain of linear array is large, and the beam width is narrow. The detection range and azimuth resolution are superior to those of other formations in non-end-to-end azimuth region.
