The Radar Imaging Lab (RIL) was established in January 2005 by a grant from DARPA made to the Center for Advanced Communications (CAC). The main objective of this well equipped Lab, directed by Dr. Fauzia Ahmad, is to support research, analysis, and development efforts related to radar imaging. The RIL provides the capabilities for examining and providing proof-of-concept of existing and newly-devised imaging techniques using real data. The goal is to create a state-of-the-art indoor radar imaging facility that is unique in the nation.
The RIL is capable of providing fully automated Doppler and scattered field measurements in fully controlled, semi-controlled, and uncontrolled indoor environments over a wide frequency range. It is equipped with a coherent pulse-Doppler ultrawideband imaging radar system and a powerful two-dimensional RF scanning system that allows large aperture, large bandwidth full-polarization imaging of stationary, rotating, and moving objects behind both exterior and interior grade walls. The Lab houses two linear positioners, each 6m long, that can emulate accelerating, vibrating, and constant velocity motion profiles. The RIL also has resources to perform measurement of the electrical properties (dielectric constant and loss tangent) of materials using a network analyzer.
The lab is currently supporting research on urban sensing, through-the-wall radar imaging, and compressive sensing radar.
