Optical moving target indicator for synthetic aperture radar images

sea target detection in polarimetric synthetic aperture radar images

study on polsar target detection essentially requires the cattering information and polarimetric statistical data. theoretical analysis shows that some terms of the second order scattering matrices such as coherence and covariance matrix clearly show the differences between nonsymmetrical man-made objects and natural clatters which being reflection symmetric. using the model derived from these ...

RapidIO-based Space System Architectures for Synthetic Aperture Radar and Ground Moving Target Indicator

The design of space systems capable of performing realtime Synthetic Aperture Radar (SAR) is a significant challenge in HPEC due to the high processor, memory, and network requirements imposed by SAR. However, building a system to support SAR and other Space-Based Radar (SBR) algorithms simultaneously is an even greater challenge. This presentation describes simulation results from a SAR applic...

Optical images-based edge detection in Synthetic Aperture Radar images

We address the issue of adapting optical images-based edge detection techniques for use in Polarimetric Synthetic Aperture Radar (PolSAR) imagery. We modify the gravitational edge detection technique (inspired by the Law of Universal Gravity) proposed by Lopez-Molina et al, using the non-standard neighbourhood configuration proposed by Fu et al, to reduce the speckle noise in polarimetric SAR i...

Theory of synthetic aperture radar imaging of a moving target

Two novel image processing techniques have been developed to refocus a moving target image from its smeared response in the synthetic aperture radar (SAR) image which is focused on the stationary ground. Both approaches may be implemented with efficient fast Fourier transform (FFT) routines to process the Fourier spatial spectrum of the image data. The first approach utilizes a matched target f...
