Algoritmo interferométrico para un sistema radar de apertura sintética circular de corto alcance

Abstract

This paper presents an interferometric algorithm capable of working with SAR images obtained from measurements carried out with antennas that describe a circular trajectory. The antennas are positioned on a vertical mast at a low height. Therefore, the system is very interesting for surface scattering studies and buried objects detection due to the very high spatial resolution that C-SAR (Circular SAR) images present. A summary of the analytical formulation of the C-SAR processor and a complete description of the interferometric algorithm are presented along. Some experimental results obtained in anechoic chamber are also shown.
