Abstract
Process for real time signal processing for side-looking synthetic aperture radar systems, the signal consisting of sample sequences corresponding to given spacing gates. For each spacing gate an operation corresponding to an auto-correlation is directly performed on the radar signal, this relating to a product signal of a sample by a phase term varying quadratically with the rank of the sample, which supplies an estimate of the Fourier components of the radar image for each gate. The invention also relates to a circuit for processing the radar signal in real time for performing the aforementioned process.
