Abstract

Microwave radar images, such as Synthetic Aperture Radar (SAR) image and Inverse Synthetic Aperture Radar (ISAR) image, are basically graphic description of radar scattering features on a target. They have been extensively applied for remote sensing, geographical mapping, weather monitoring and radar surveillance purposes. Specifically for the surveillance application, ISAR imaging provides an effective way for automatic target recognition. In this seminar, the basic principle for radar imaging will be introduced first, followed up by a presentation of novel techniques for high quality ISAR image formation from radar data recorded in real, tough environment. The adaptive joint time-frequency techniques will be utilized to perform target motion compensation and Doppler artifact removal and feature extraction for targets with fast rotating parts. Imaging results for real-world measured data will be presented to illustrate the effectiveness of the alogrithms.

Biography

Mr. Wang obtained his Bachelor degree from University of Science and Technology of China in 1993, Master degree from University of Texas at Austin in 1996, both in electrical engineering. He is expected to obtain his Ph.D from University of Texas at Austin in August, 1999. His research interest includes modeling and simulation of electromagnetic scattering and microwave circuits, SAR/ISAR image processing, time-frequency techniques.
