Title: Michael William Greenwood: Innovator in Radar Altimeter Technology
Introduction
Michael William Greenwood is a notable inventor based in Maple Grove, MN (US), recognized for his contributions to radar altimeter technology. With a total of four patents to his name, Greenwood has made significant advancements in methods and systems that enhance the functionality and accuracy of radar altimeters.
Latest Patents
Among his latest patents, Greenwood has developed innovative methods for piecewise curve fitting of radar altimeter range gate data. This method compensates for range gate slide concerning received returns within a radar altimeter. It involves adjusting the overlap between a range gate pulse and a radar return signal until the altitude output is within a desired tolerance. Additionally, the method incrementally increases the attenuation within the receiver circuit until the radar altimeter breaks track with the radar return signal. It also includes recording signal strength and altitude output at each increment of attenuation, determining altitude error, and fitting the signal strength data against the altitude error using variable length line segments.
Another significant patent by Greenwood is focused on automatic zero calibration of radar altimeters. This method operates a radar altimeter to perform zero altitude calibration by determining the difference between the measured altitude and the desired altitude indication. Upon receiving a zero calibration command, the method subtracts this difference from the altitude output of the radar altimeter.
Career Highlights
Throughout his career, Greenwood has worked with prominent companies such as Honeywell GmbH and Honeywell International Inc. His experience in these organizations has allowed him to refine his skills and contribute to cutting-edge technology in the field of radar systems.
