Moving Targets in Synthetic Aperture Images: A Bayesian Approach
نویسندگان
چکیده
This paper presents a novel method to determine the complete velocity vector of a moving target using a single Synthetic Aperture Radar (SAR) sensor. The method exploits the structure of the returned echo from a moving target: in the slow-time frequency domain, it is a scaled and shifted replica of the antenna radiation pattern immersed in Gaussian noise; the scale and the shift are related with the slant-range and the cross-range velocities, respectively. A Bayesian approach is then adopted to derive an estimator for the velocity vector. Simulation results illustrating the estimator effectiveness are presented.

Improving the quality of ultrasound images using Bayesian estimators
Medical ultrasound imaging due to close behavior of cancer tumors to body tissues has a low contrast. This problem with synthetic aperture imaging method has been addressed. Although the synthetic aperture imaging technique solved the low-contrast problem of ultrasound images, to an acceptable limit, but the performance of these methods is not even acceptable when the signal to noise ratio (SNR...
متن کاملDetecting moving targets in multiframe SAR imagery without using any direct backscatter
Detecting moving targets using Synthetic Aperture Radar (SAR) imagery is challenging since target images become highly distorted due to the unknown motion of the target. The distortions include smearing, and displacement, of the target signal across the SAR image. This paper reports an approach to moving target detection which avoids these distortions by operating on the target’s shadow. Unlike...
متن کاملSpeckle Reduction in Synthetic Aperture Radar Images in Wavelet Domain Using Laplace Distribution
Speckle is a granular noise-like phenomenon which appears in Synthetic Aperture Radar (SAR) images due to coherent properties of SAR systems. The presence of speckle complicates both human and automatic analysis of SAR images. As a result, speckle reduction is an important preprocessing step for many SAR remote sensing applications. Speckle reduction can be made through multi-looking during the...
متن کاملMoving target inference with hierarchical Bayesian models in synthetic aperture radar imagery
In synthetic aperture radar (SAR), images are formed by focusing the response of stationary objects to a single spatial location. On the other hand, moving targets cause phase errors in the standard formation of SAR images that cause displacement and defocusing effects. SAR imagery also contains significant sources of non-stationary spatially-varying noises, including antenna gain discrepancies...
متن کاملSAR Imaging of Moving Target based on Knowledge-aided Two-dimensional Autofocus
Due to uncertainty on target's motion, the range cell migration (RCM) and azimuth phase error (APE) of moving targets can't be completely compensated in synthetic aperture radar (SAR) processing. Therefore, moving targets often appear two-dimensional (2-D) defocused in SAR images. In this paper, a 2-D autofocus method for refocusing defocused moving targets in SAR images is presented. The new m...
