Introduction

Douglas Fraedrich is a notable inventor based in Alexandria, VA (US). He has made significant contributions to the field of signal processing, particularly with his innovative patent that addresses the challenges of differentiating between target signals and background clutter.

Latest Patents

Fraedrich holds a patent for a Dual Waveband Signal Processing System (DWSPS). This system is designed to differentiate between a primary target signal and background noise, enabling the detection of targets and objects with unique spectral characteristics. The DWSPS utilizes multiple sensors operating on different wavelengths. The output wavebands from these sensors are filtered using spatial or temporal high-pass filters. The processed data is then analyzed through a network of multipliers, dividers, comparators, and subtractors to produce weighted correlation functions, known as the 'alpha coefficient'. This innovative approach results in a filtered output signal that enhances the detection of specific features.
