海底阵型校阵误差评估方法
Evaluation Methods on Array Measuring Error of Seabed Arrays
摘要
Abstract
The measuring theory for seabed acoustic arrays is divided into absolute array measuring and relative array measuring .Absolute array measuring takes much time ,but it has high precision of array measuring .Relative array measur-ing is in contrast to absolute array measuring .Comparering with the two measuring method ,three methods of array measur-ing error in evaluating seabed acoustic arrays are given ,which can help us find a better sailing path .The method one is pre-diction error ,which marks the error's direction and size as a point in a picture and estimates the error of the point as array measuring error .The method two is making use of modeling and simulation and calculating the array measuring error .The method three is calculating error by use of the error equation .Comparing the three methods ,it is concluded that the three methods are of consistency on the change rule in the error trasfering ,and the method one has advantages of graphics intuition and calculating fast ,and the method two is reliable .关键词
