The existing linear-frequency-modulated (or step frequency) and random noise synthetic aperture radar (SAR) systems may correspond to the frequency-hopping and direct-sequence spread spectrum systems ...

All the latest science news on synthetic aperture radar from Phys.org. Find the latest news, advancements, and breakthroughs.

Synthetic aperture radar (SAR) is a way to make sharp pictures even when it’s dark or cloudy. Instead of using visible light like a regular camera, SAR systems send out microwave pulses and ...

This paper presents the correlating synthetic aperture radar (CoSAR) technique, a novel radar imaging concept to observe statistical properties of fast decorrelating surfaces. A CoSAR system consists ...
