Title: Edward J Groth, Jr: Innovator in Monopulse Tracking Systems

Introduction

Edward J Groth, Jr. is a notable inventor based in Scottsdale, AZ (US). He has made significant contributions to the field of communications and tracking systems, holding a total of 6 patents. His work has been instrumental in advancing technologies that enhance the reliability and efficiency of data transmission.

Latest Patents

Among his latest patents is a monopulse tracking system that is substantially free of externally generated noise. This innovative system utilizes at least two channels, each associated with a different spreading/despreading pseudo-random noise function. In conjunction with a monopulse antenna, one channel develops a sum signal while the other develops a difference signal. These signals are then used in a phase detector to generate an error signal, effectively eliminating biases caused by noise. Another significant patent is for a multiple channel data link system, which provides a coherent communications link for transmitting intelligence across multiple non-contiguous frequency channels. This system employs coherent carrier signals that are connected to a single composite intermediate frequency signal upon reception by a fully coherent receiver.
