A novel high-resolution time-frequency representation method is proposed for source detection and classification in over-the-horizon radar (OTHR) systems. A...
We introduce the quadratic sensor angle distribution (SAD) for near-field source characterization. The SAD is a joint-variable distribution and a dual in...
The fundamental objective of this research project is to improve the GPS receiver performance when subjected to strong nonstationary interference. The...

The project has focused on advancing the theory of time-varying spectrum analysis and its applications to the important area of sensor array processing. We...
This is the Proceedings of the 10th IEEE Workshop on Statistical Signal and Array Processing (SSAP), which was held at the Pocono Manor Inn, Pocono Manor, Pa...
Time-Frequency distribution are being recognized as powerful tools in signal analysis and processing. Although time-frequency analysis has been of interest for...

This report includes results on the applications of time frequency distributions in blind source separation and direction finding problems. A novel approach...
The objective of this multi-year research funding is to devise new and novel methods to suppress interferers impinging on a multi-sensor GPS receiver. The...
We examine the performance of the delay lock loops (DLL) in GPS receivers in the presence of non-Gaussian noise. interference and noise sources for GPS...
