Title: David A. Lucas: Innovator in Radio Source Direction Determination

Introduction

David A. Lucas is a notable inventor based in Crawley Down, GB. He has made significant contributions to the field of radio technology, particularly in determining the direction of radio sources. With a total of 2 patents to his name, Lucas has demonstrated his expertise and innovative thinking in this specialized area.

Latest Patents

Lucas's latest patents include a method for determining the direction of a radio source. This method utilizes a circular array of aerials to create a sinusoidal phase graph. The direction of the radio source relative to a reference direction is determined from one or more zero crossings of this phase graph. Additionally, he has developed a technique for resolving angular ambiguity, especially in measurements made in radio interferometers. This technique involves comparing an ambiguous value for a desired angle with an unambiguous value, ideally equal to the desired angle, but differing by an error angle of less than π. For instance, ambiguity in the phase difference between widely spaced antennas can be resolved by referencing the sum of two unambiguous phase differences between each antenna and an intermediate antenna.
