The article presents the one element of the autonomous maritime positioning system which task is the identification of characteristic points generated from the radar image. The system to fix position in automatic way requires extraction of characteristic points, their identification and subsequently in the last calculation step an application of classical methods of the radar navigation. The present...
The article describes one of the radar image compression methods - the "invariant" method. Furthermore, evaluation of the "invariant" method in the context of its application in the designed maritime coastal positioning system is presented. Influence of the "threshold", the median filter and FFT transform to a final form of compressed image is also considered.
