Title: Julia R. Baryl and Radar Receiver Gain Control

Introduction

Julia R. Baryl is an inventor associated with Kirkland, Washington, and Honeywell International Inc. Her patent work concerns automatic gain control in multichannel radar receivers, where accurate signal handling supports reliable radar operation.

Latest Patents

Baryl is credited with 1 patent: “Systems and Methods for Automatic Gain Control for Multichannel Receivers.” The invention describes methods for performing automatic gain control in a radar system.

In one embodiment, an attenuator adjusts the gain of signals received from a radar receiver. A digital signal processor uses digitized noise data from multiple channels to determine coarse gain correction, then calculates fine gain correction from the remaining error. It also determines a frequency-versus-gain curve correction using the channel data and a mathematical model of the radar system’s gain across the noise spectrum.

The processor sends a gain control signal to the attenuator for hardware adjustment and provides a channel-specific scale factor for software gain control. In one embodiment, it generates the gain control signal while the radar system is in inactive scan mode.

Career Highlights

Baryl’s listed patent reflects work on combining hardware and software techniques to manage gain across multiple radar channels. The approach accounts for both residual signal error and frequency-dependent gain variation.
