Methods for Complexing Images Formed by Multi-Band Synthetic Aperture Radars

Adaptive resource allocation for synthetic aperture radars under resource constraints

In along-track synthetic aperture radar systems, measurements from multiple phase centers can be used to remove bright stationary clutter in order to detect and estimate moving targets in the scene. The effectiveness of this procedure can be improved by increasing the number of antennas in the system. However, due to computational and communication constraints, it may be prohibitive to use a la...

High Resolution Ocean Surface Wind Fields Retrieved from Spaceborne Synthetic Aperture Radars Operating at C-band

This paper introduces algorithms designed to retrieve high-resolution ocean surface wind fields from satellite borne synthetic aperture radars (SARs) operating in C-band at either vertical (VV) or horizontal (HH) polarization in transmit and receive. Wind directions are extracted from wind induced streaks that are visible in SAR images at scales above 200 m and that are approximately in line wi...

Techniques for ground moving target detection and velocity estimation with multi-channel Synthetic Aperture Radars (SAR)

Understanding Synthetic Aperture Radar Images

Detection/Tracking of moving targets with synthetic aperture radars

In this work, the problem of detecting and tracking targets with synthetic aperture radars is considered. A novel approach in which prior knowledge on target motion is assumed to be known for small patches within the field of view. Probability densities are derived as priors on the moving target signature within backprojected SAR images, based on the work of Jao. Furthermore, detection and trac...
