Enormous efforts have been devoted to the data acquisition, signal processing, and automatic recognition of stationary or moving targets. However, the move-stop-move ground targets are much more difficult to detect and localize since the detection of such challenging targets may require multiple… More

The satellite-based GPS systems are vulnerable to intentional and unintentional interferences. Much work has been done on the development of anti-jam techniques using adaptive arrays for GPS receivers. Almost all of the anti-jam techniques proposed are based on the standard Capon beamformer or its… More

Geometric or angular diversity can be exploited to significantly enhance ultrahigh frequency (UHF) synthetic aperture radar (SAR) imaging performance, to capture target glints, to exploit highly directional specular returns, to achieve enhanced resolutions in both planar dimensions without… More

Multi-input multi-output (MIMO) radar has been attracting significant interest in recent years. One of the most promising application areas of MIMO radar is to develop MIMO radar based smart electronic bumpers to overcome rotorcraft brownout challenges that can cause major landing mishaps. MIMO… More

The security of the United States"naval ships, ports, and waters are of tantamount importance. These crucial assets are vulnerable to attack from small, nimble adversaries that can hide within the near-constant evaporation duct present over large bodies of water. This scenario can be quite… More

In the proposed program, we will first perform a detailed investigation of the effects of various temporal and spectral interruptions on SAR image quality and utility. We will then develop innovative interrupted SAR imaging algorithms using the state-of-the-art sparse signal recovery (SSR)… More

This Small Business Technology Transfer (STTR) Phase I project aims at addressing the challenging issue of spectrum scarcity for high throughput wireless communication systems by developing an innovative cognitive radio (CR) communication system capable of operating within a fragmented spectral… More

This SBIR project aims to address one of the greatest challenges in the Counter-Rocket, Artillery and Mortar (C-RAM) area, i.e., high-speed low-RCS target detection. To tackle this challenge, an innovative moving target detection scheme, including a simple but effective range/Doppler migration… More
