摘要
针对水母探测问题,提出了基于高分辨率多波束声成像的水母探测方法,进行了真实环境下的海月水母探测试验,分析了海月水母个体回声特性。在试验中,探测得到清晰的水母声图像,验证了利用声学探测水母的可行性。在海月水母的声图像中发现四个明显的回声亮点,这是由海月水母的四个胃囊产生的强反射。同时利用海月水母个体的声图像估计了目标的直径。
In view of jellyfish detection, a method based on acoustic image using high resolution multibeam acoustic image forming technique, a noon jellyfish detection experiment was conducted on sea, and echo characteristics of individual moon jellyfishes were analyzed. In this experiment, clear acoustic images of individual moon jellyfish were obtained, acoustic method was verified available in moon jellyfish detection. In individual moon jellyfish echo images, four evident echo highlights were found, which were due to the four stomachpouchs. Acoustic diameter of moon jellyfish was estimated with the acoustic image.
