Conventional passive multistatic radar systems, which are comprised of multiple transmitters and receivers, detect and localize targets in a two-stage process. First, detections are performed independently for each bistatic transmit-receive pair. A multilateration process then uses the resulting bistatic range estimates to localize the targets in Cartesian(More)
A spatial filtering method is introduced for improving continuous-wave inverse synthetic aperture radar (ISAR) measurements in a partially controlled chamber. Twodimensional angle of arrival (AoA) estimation using a modified matrix pencil algorithm first identifies directions of interference sources outside the target zone. Then, each radar sweep is(More)
Attributed scattering center models can relate radar measurements to physical target features. This paper summarizes recent signal processing methods for attributing synthetic aperture radar images with emphasis on feature space definition for object recognition. Examples using laboratory measured inverse synthetic aperture radar data and simulated data are(More)
—A new modeling method for representing distributed scattering centers in wide-angle synthetic aperture radar (SAR) is presented. The proposed multipeak model approximates amplitudes of localized image peaks that typically appear at a single pixel or as an in-line set of pixels in a SAR image. In this way, the multipeak model is an improvement over existing(More)
