摘要
在探测区域存在多个目标的情况下,水声岸站被动测向定位系统必须首先解决多目标的航迹关联问题,即确定各个传感器所测量的信息哪些是来源于同一目标的。通过融合被动声纳所测量到的方位和时延信息提出了一种方位最近邻关联方法,对该方法和传统的多维分配算法进行仿真表明该方法能获得很高的正确关联概率,同时该方法克服了传统的多维分配算法在传感器和目标数量较多时计算量过大的问题,是一种优于多维分配算法的水声被动多传感器多目标航迹关联方法,这说明利用信息融合手段解决水声领域航迹关联问题具有潜在的优势。
When there are more than one target in the detecting area, the track correlation problem of multi- target must be solved first by the system of underwater sound location, it means to make clear which information measured by the multi-sensors are from the same target. An azimuth closest method based on fusion of azimuth and time-delay information is provided in this paper. The simulation indicates that this method can get a high correct correlation probability , and compared to the traditional method-S-D assignment method, this method has fewer calculation quantity, so it is a better method to solve the problem of underwater sound multi-sensor multi-target track correlation. It indicates that the information fusion method has potential advantage for solving the track correlation problem of underwater sound ：system,
