ABSTRACT:
Recursive system for the forming of a radar image by means of a SAR sensor, for application preferably related to the radar field, essentially having a monodimensional transformation system (1) of the signal received by the radar; a convolution element (2) of the same signal by means of a monodimensional inverse transformation (3). The result of the convolution is retro-projected by means of element (4). In turn, the result of this operation, envelope-detected (5), provides an estimate of the electromagnetic characteristics of the teledetected scene. The invention belongs to the radar application field, and more precisely to that of synthetic aperture radars for teledetection. It finds its best application in the area of synthetic aperture radar signal processing.
