水面舰艇通过敏感海域时,被动声呐操作员需集中精力观测声呐图像及水下/水面目标态势来人工提取关键信息,长时间工作存在漏报误报的风险。针对该问题提出一种基于机器视觉的被动声呐战位辅助操作技术。首先,运用突变信号检测算法提取声呐图像中威胁目标突变信号;其次,运用轨迹检测算法提取威胁目标宽带轨迹、窄带轨迹等关键特征;然后,再综合利用已知水面/水下目标态势、被动声呐关键特征、不同态势下权重因子,生成声呐有效观测范围内来袭目标的威胁判断;最后,根据威判结果自动控制声呐进行威胁目标跟踪。本技术可有效减轻声呐操作员的工作强度,缩短人为反应时间,降低漏报误报风险,提高威胁目标对抗效能。

Passive sonar operator of a ship needs to concentrate on observing sonar interface and underwater or surface target situation for a long time to extract key information manually maritime operations when surface vessels pass through sensitive waters, there is the risk of missing and false alarm. A station auxiliary operation technology for sonar digital image processing based on machine vision is proposed. First, the transient signal detection algorithm is used to extract the threat target mutation signal. Secondly, we use trajectory detection algorithm to extract key features of target, such as wideband trajectory and narrowband trajectory. Then, the threat judgment of an incoming threat target in each position within the effective observation range of sonar is generated by synthetically using the situation of a surface or underwater target. Finally, the sonar is automatically controlled to track the threat target according to the result of arbitrage. This technology can effectively reduce the work intensity of sonar operation, shorten the risk of false alarm and improve the threat target adversarial efficiency.
