Abstract

"In the improvised explosive device detection research, the goal was to create time-frequency representations, or TFRs, of signals generated by various radio frequency receivers in their passive listening state and to then identify characteristics unique to specific types of receivers. These characteristics, or features, could then be utilized to detect and classify the receivers. In order to accomplish this goal, it was necessary to implement an algorithm to produce accurate and clear TFRs of the time-varying signals. Building upon a parametric estimation technique, which consisted of an optimal weighted averaging of multiple TFR spectrograms, preprocessing and filtering routines were inserted into the existing algorithm in order to increase the robustness and stability of the estimation"--Abstract, page iii.
