DN-1型水声指令应答器是通过发出水声指令信号的方式去接通水下仪器的电源,达到指令其工作的目的,并通过接受水声回答信号的方式来监视水下仪器的工作正常与否。该应答器已用于山东海洋学院海洋物理系研制的“散射仪”上。经过几次海上实验证明,在投放深度50米以内(50米以上未实验)、水平距离300米以内,该应答器都能可靠地工作。 DN-1 underwater acoustical transponder is through the way of sending underwater acoustical command signal to turn on the power of submerged instrumentation to achieve the purpose of commanding its work, and to monitor the work of underwater instrumentation by receiving signals of underwater acoustics Normal or not. This transponder has been used in the “scatterometer” developed by the Marine Physics Department of Shandong Ocean University. After several sea experiments prove that the transponder can work reliably within the depth of 50 meters (not more than 50 meters) and the horizontal distance is within 300 meters.
