WebAug 16, 2024 · A synthetic aperture is created from consecutive measurements of a moving radar. SAR obtains fine angular resolution by synthesizing a large antenna aperture based on the sensor motion. Given the sensor locations, consecutive radar measurements can be processed as if they were acquired by a single large antenna array.
