【摘要】 以测得的误差声速剖面作为初始猜测值,利用多波束记录到的波束传播时间和波束角等信息,通过广义线性反演得到一个与实际声速剖面比较接近的声速剖面,这有助于减少声速剖面的误差。通过理论模型计算,验证了该方法的可行性和正确性。更多还原

【Abstract】 In this paper,taking the measured error sound velocity profile as the initial guess value,the sound beam travel times and beam angle recorded by the multi-beam system and the generalized linear inversion method are used to get a sound velocity profile close to the actual sound velocity profile,and the inversed sound velocity profiles have contributed to the reduction of sound velocity profile error.The theoretic model computed results have verified the feasibility and correctness of the inversion method.更多还原
