阅读说明：本技术 一种潜水员使用的便携成像声呐系统 (Portable imaging sonar system for diver ) 是由 杨睿 吴丹青 吕冰冰 肖志伟 于 2021-06-21 设计创作，主要内容包括：本发明提供一种潜水员使用的便携成像声呐系统,包括潜水员头盔和腰部处理盒,潜水员头盔包括多波束成像声呐、水下摄像机、OLED眼镜和照明灯,潜水员头盔内设置有分系统嵌入式软件；多波束成像声呐包括接收换能器、FPGA及电信号和模拟信号转换处理模块、FPGA数字信号处理控制模块发射换能器；腰部处理盒对头盔采集的数据采用综合信息处理与线控软件进行无源目标定位算法计算潜水员所跟踪目标的位置。本发明提供的系统通过构建无源定位目标模型,并采用最大似然估计法求取最优解,并能够采用HUD二维眼镜集中盔显的头盔实时呈现被监测区域各个被监测目标的图像的,具有作用距离远,隐蔽性好和抗干扰能力强等优点。(The invention provides a portable imaging sonar system used by a diver, which comprises a diver helmet and a waist processing box, wherein the diver helmet comprises a multi-beam imaging sonar, an underwater camera, OLED glasses and a lighting lamp, and subsystem embedded software is arranged in the diver helmet; the multi-beam imaging sonar comprises a receiving transducer, an FPGA, an electric signal and analog signal conversion processing module and an FPGA digital signal processing control module transmitting transducer; the waist processing box calculates the position of a target tracked by a diver by adopting a passive target positioning algorithm of comprehensive information processing and wire control software on data acquired by the helmet. The system provided by the invention can adopt the maximum likelihood estimation method to obtain the optimal solution by constructing the passive positioning target model, can adopt the helmet which is intensively displayed by HUD two-dimensional glasses to display the images of all monitored targets in the monitored area in real time, and has the advantages of long action distance, good concealment, strong anti-interference capability and the like.)
