Title: Arthur J Tardif: Innovator in Signal Detection Technologies

Introduction

Arthur J Tardif is a notable inventor based in Amherst, NH (US). He has made significant contributions to the field of signal detection, holding a total of 5 patents. His work primarily focuses on developing systems and methods for detecting unknown signals, particularly in radar technology.

Latest Patents

Among his latest patents is the "Orthogonal Polarization Signal Agnostic Matched Filter." This invention presents a system and method for detecting unknown signals that may be radar pulses. The method involves conjugate multiplying a first signal with a second signal to produce a first multiplied signal, while also conjugate multiplying the second signal with a third signal to produce a second multiplied signal. The radar pulse is contained in all three signals, each of which has noise components. The first multiplied signal is integrated to produce a first integrated signal, and the second multiplied signal is integrated to produce a second integrated signal. These integrated signals are summed to detect the location of a peak power, which is crucial for determining the time of arrival (TOA) of the radar pulse.

Another significant patent is the "Signal Agnostic Matched Filter Parameter Estimator." This system includes a receiver, multiplier logic, integrator logic, and peak detection logic. The receiver captures a first radio frequency (RF) input containing an unknown signal and noise, along with a second RF input that is orthogonally polarized with respect to the first. The multiplier logic processes these inputs to produce a multiplied signal, which is then integrated to yield an integrated signal. The peak detection logic determines a coarse TOA of the unknown signal based on the peak power in the integrated signal.
