Solution to hardware-in-loop simulation test system for Phased Array Doppler Sonar

A solution is put forward to hardware-in-loop simulation test system (HSTS) on land for phased-array doppler sonar (PADS), including HSTSpsila composition, principle and the structure of acoustic coupling device (ACD). The mathematics model of ACD is deduced. Acoustics pressure distribution is calculated and simulated in near field of ACDpsilas transducer array. The principle and method, being used to design the receiving/transmitting transducers of ACD, is also presented.
