由于空间分辨率低,两声呐纯方位目标关联存在关联模糊性,从而产生虚假目标(幻影)。当两声呐配置距离较近时,利用两声呐同目标的方位相似性,提出方位门快速关联,消除关联的模糊性,分析配置距离和目标方位对关联门的影响,提供目标早期接触跟踪关联方法。随着跟踪的进行,在具有初步的距离范围信息的情况下,提出距离范围方位门关联方法,提供目标接近态势下的目标关联。计算机仿真说明这2种方法的有效性。
Bearing-only association with two sonar systems, produces the false target (ghost), because the association ambiguity due to no distance information. Based on the bearing similarity in different sonar system for same target, bearing-door association method is proposed when two sonar systems are deployed in shorter distance. The size of bearing-door is analysis with several parameters such as sonar detection distance, systems base line length and the bearing of target. Bearing-door association method with target distance bound information is also discussed. Computer simulations show that proposed methods is validity for shorter distance deployment sonar systems.
