Abstract :
The information about shape and geometrical dimensions of the moving target can be extracted using Doppler spectrum. The short observation time interval corresponds to constant speeds of target scatterers as well as low resolution by Doppler frequency shift. Methods of spectral estimation are applied to identify the scatterer parameters. Two methods of a target Doppler spectrum model order selection based on information criteria are presented.
