Application of r-contiguous-bits scheme borrowed from immune systems to characteristic points of radar image identification

Abstract


The problem of continuous position availability is one of the most important issues connected with human activity at sea. Since the availability of satellite navigational systems can be limited in some cases, for example during military operations, we should consider other methods of acquiring information about ship's position. One of such methods is to apply information included in a radar image of a coast. The positioning system extracts characteristic points from the radar image, identifies them, i.e. assigns correct location to each of them, and finally fixes ship's position using previously identified points as reference points. In this paper, a new method of identification of radar image characteristic points is presented which is an adaptation of r-contiguousbits scheme borrowed from immune systems. The method proposed compares coastlines visible from radar image points with pattern coastlines generated from navigational chart.
