摘要
针对声全息技术在实艇测试中存在的海底声反射问题,结合镜像法和半空间声全息理论,通过仿真计算,研究了某海区海底声反射对声全息测试结果的影响.结果表明,海底吸声量越大、测试精度和声源频率越高,则测试误差越大.
The relevant research wok is carried out on the seabed sound reflection which has influence on the result of real-boat tests based on the acoustic holographic technology.The effect of seabed reflection on underwater acoustic test is analyzed through simulating the sound field of free field and semi-free field.The result shows that higher underwater sound absorbing,test accuracy and sound resource frequency would result in bigger test errors.
