Reconstruction and recognition of the radar target image

Abstract

A method for generating the spatial image of several types of jets is presented. The method consists in applying the Radon transform to a data set containing discrete values of the frequency characteristic of the objects under study, for several illumination angles. A Matlab program was developed for image reconstruction. The contour shape of the images is used for recognition of jet type. Fourier descriptors are calculated in order to provide a good characterisation of the contour shape. An analysis of the quality of the image recognition is made with respect to the number of profile functions used for object image reconstruction.
