    • A fishfinder is provided for identifying with high precision a single fish under the ship and for measuring the length of the fish precisely. An operator of the fishfinder is assisted to grasp the depth and the length of the fish. A fishfinder transmits an ultrasound pulse having a high carrier frequency and an ultrasound pulse having a low carrier frequency by means of a pulse transmission and reception device at predetermined time intervals. A single fish echo is determined and tracked for a plurality of transmission intervals of ultrasound pulses emitted into the water. A target strength of single fish is measured based on the signal strength of a low carrier frequency echo signal from the single fish. The length of the fish is measured based on the target strength. A fish mark is displayed on the screen of an indicator, with the size of the fish mark depending on the fish length.
    • 提供了一种钓鱼器,用于高精度识别船下的单鱼,并精确测量鱼的长度。 帮助捕鱼者的操作者抓住鱼的深度和长度。 钓鱼器以预定的时间间隔通过脉冲发送和接收装置发送具有高载波频率的超声脉冲和具有低载波频率的超声脉冲。 确定并跟踪发射到水中的超声脉冲的多个传播间隔的单个鱼回声。 基于来自单个鱼的低载波频率回波信号的信号强度来测量单个鱼的目标强度。 基于目标强度测量鱼的长度。 鱼标记显示在指示器的屏幕上,鱼标的大小取决于鱼的长度。
