The authors made an attempt to estimate the overall length of a vessel indicated as a target on a radar PPI. It was assumed that an estimate of the overall length was given by the formula of a linear multiple regression model. To find estimates of parameters appearing in a functional dependence between variables, we applied the method of least squares. The variables of the function were experimentally determined from the measures of an image on a radar PPI by using the image processing techniques. In this report we are going to report on the results of measurement from the marine traffic survey in Akashi channel obtained by using the aforementioned method. The conclusions are as follows. As for the results of comparison between the data estimated from the linear multiple regression equation and those from the actual ship, the agreement is remarkably good. The improvement of the image processing techniques shows the possibility of the automatic analysis of the marine traffic.
