Holographic polar formatting and real-time optical processing of synthetic aperture radar data

Not Accessible

Your library or personal account may give you access

Abstract

A two holographic optical element (HOE) system for polar formatting of spotlight mode synthetic aperture radar (SAR) data was designed, fabricated, and successfully tested. With the addition of a spatial light modulator, a third phase-compensating HOE, and a Fourier transform lens, the real-time polar formatting of SAR data and SAR image formation was experimentally demonstrated.
