Abstract: | Synthetic aperture radar (SAR) imaging for arms control verification is discussed. SAR images are particularly suited for verification purposes because their image resolution capabilities are independent of weather conditions, surface penetration, and lighting. Their restrictions are related to data handling and power requirements. Verification requirements, imaging radar principles, target characteristics, and resolution are considered. The choice of frequency and the advantages of diversity are examined. Hardware and data-rate considerations are discussed. Past, present, and future spaceborne SAR systems are briefly surveyed |
