In order to meet various test objectives of active acoustic detection for underwater equipment and to improve its development efficiency，an measurement system for active acoustic detection based on virtual instrument is proposed in this paper. Its software adopts modularity and hierarchical structure，and is designed based on LabWindows/CVI platform. It uses modules of the platform，such as signal detection，signal generation，signal analog output，etc. Measurement of active acoustic detection signals，simulation of target echo，generation of reverberation and interference，and injection of electronic signals can be realized by this system. With high degree of automation and flexible parameter setting，it is suitable for simulation test and efficiency evaluation of various active acoustic detection.
