Study of Estimating Shape by Integrating Radar Images : Integration Experiment by Use of Multi-Radar

Abstract

We have proposed a method to estimate the shape of a ship by means of the integration of radar images obtained by the observation from some directions. In making this method fit for practical use, the observation by multi-radar set on a land or a ship is needed. In this case, the estimation can be affected by errors included in the obtained images. And they are errors in the range direction and the cross range direction of each radar. Therefore, estimating the shape of a ship by integrating the images should be carried out after applying an adjustment of them. In this study, an adjustment method for correcting the errors is proposed. And the accuracy of the estimation of a shape is cleared by an experiment. As results of the experiment, the accuracy of about 2 degrees in direction, about 14 meters in length and about 9 meters in beam was obtained.
