This Small Business Innovation Research (SBIR) Phase II Project will develop a broadband split-beam fisheries sonar system for shallow water applications. As the number of fish in rivers and streams diminishes and becomes threatened, endangered or extinct, there is a need for better fish monitoring tools for such shallow water environments. Through a series of workshops, the leaders in the riverine sonar community have highlighted several deficiencies in the current monitoring systems. This Phase II Project proposes to build a fish tracking and counting system that addresses many of these deficiencies, and that has a ten-fold better range resolution and at least a 6 dB improvement in detection. The broadband sonar system, to be built in the course of this project, will include (a) a unique bizonal shaded transceiver array, (b) a full complement of functions for collection, storage, analysis and display of data, and (c) a multi-hypothesis tracker for tracking fish in low SNR and dense target environments. The sonar system will be validated first in a comprehensive set of pool tests, and then subjected to a rigorous set of evaluation experiments in the Kenai and Copper Rivers of Alaska and in the Rogue River of Oregon.The commercial applications of this project are in a broad range of markets that require fish counting and tracking equipment. The overall market size for such equipment worldwide is estimated to be on the order of 1.8 billion dollars.

这项小企业创新研究（SBIR）第二阶段项目将开发用于浅水应用的宽带分束渔业声纳系统。随着河流和溪流中的鱼类数量减少，受到威胁、濒危或灭绝，需要更好的鱼类监测工具来监测这种浅水环境。通过一系列的研讨会，河流声纳界的领导们强调了当前监测系统的几个缺陷。该二期项目建议建立一个鱼类跟踪和计数系统，以解决这些缺陷，并具有10倍的距离分辨率和至少6db的检测改进。该宽带声纳系统将在该项目中建造，将包括(a)一个独特的带状阴影收发器阵列，(b)收集、存储、分析和显示数据的完整功能，以及(c)一个多假设跟踪器，用于在低信噪比和密集目标环境中跟踪鱼类。声纳系统将首先在一组全面的水池测试中进行验证，然后在阿拉斯加的基奈河和铜河以及俄勒冈州的罗格河进行一组严格的评估实验。该项目的商业应用范围广泛，需要鱼类计数和跟踪设备。据估计，全球此类设备的整体市场规模约为18亿美元。
