摘要
本文分析了水库湖泊等浅水区域鱼群探测的困难，研究了把调频声波用了浅水探测的可能性，提议用调频声纳阵来提高探测的距离分辨率和角度分辨率。理论研究和计算机模拟都表明此方法是可行的。
The paper analyses difficulties in detecting fish school in the shallow water areas such as reservoirs Qnd lakes. It surveys the possibility of shal- low water detection by FM ultrasonic wave and proposes utilizing an FM sonar array to improve the range resolution and the angular resolution. The theoretical research and computer simulation have shown the feasibility of this scheme.
