Generation Of Synthetic Aperture Radar Images Using Acousto-Optics

The applicability of Synthetic Aperture Radar (SAR) imaging to many practical problems is severely limited by the excessive computational load associated with the technique. In this paper we describe a simple real-time, SAR processor which is implemented with acousto-optic and charge-coupled devices. This device will be useful in applications where real-time image formation is essential and in applications where present processors are not cost effective. It could also be used to preview large sets of imagery. The device is very compact and hence it has the potential to operate aboard the vehicle that collects the SAR data.
