Workshop 2.1
Advanced Concepts in SAR Signal Processing

Dr. Mehrdad Soumekh - M. Soumekh Consultant & SUNY

Thu, 29 April 2004, 1:30 PM - 5:30 PM

Abstract

This course is intended to provide a signal theory framework for understanding the functional properties of a Synthetic Aperture Radar (SAR) signal, and its applications in specialized data processing problems in high-resolution and/or wide-bandwidth/wide-beamwidth SAR systems. The specific concepts that are examined are:

Coherent subaperture digital-spotlighting and imaging

2D (radar frequency and aspect angle) auto-calibration (focusing) to compensate for range-gate slip, GPS/INS errors, radar beam imperfections, and variations in terrain elevation; auto-calibration using in-scene targets

Moving target detection using along-track monopulse SAR; blind calibration of multi-channel SAR data for moving target indication (MTI); moving target imaging

Electronic Scanning Array (ESA) airborne radar for high-resolution and high-SNR azimuth-scanning SAR, and MTI

Blind calibration and GPS-based spatial and spectral registration of delta-heading multi-pass SAR data for coherent change detection (CCD)

ECCM for SAR using pulse diversity and PRF staggering, and associated signal processing and imaging algorithms

The mathematical concepts and algorithms will be demonstrated using the UHF-band NP-3 data, L-band MCARM data, and X-band DCS data.

Bio

Mehrdad Soumekh has served as a consultant on synthetic aperture radar signal processing for the government and industry. He has held visiting appointments at Naval Command, Control and Ocean Surveillance (SPAWAR Systems) Center, San Diego, California; Air Force's Phillips Laboratory, Albuquerque, New Mexico; Air Force's Rome Laboratory, Rome, New York; MITRE Corporation, Bedford, Massachusetts; and Air Force's Wright Laboratory, Dayton, Ohio. His recent work includes projects with AFRL-Eglin (SAR Seeker Program), AFRL-Rome (Multi-Channel SAR Program), AFRL-Wright Patterson (TUT Program), ARL-Adelphi (FOPEN-GPEN SAR Program), and ONR (Nonlinear SAR Program). He is the recipient of two AFOSR-DURIP grants (1999 and 2002) to develop a high performance computing laboratory for SAR data processing. He is the author of the books ?Fourier Array Imaging? (Prentice Hall, 1994), and ?Synthetic Aperture Radar Signal Processing with MATLAB Algorithms? (Wiley, 1999). He is currently a Professor of Electrical Engineering at the State University of New York at Buffalo.
