Title: David Herbert Brandwood: Innovator in Antenna Technology
Introduction
David Herbert Brandwood is a notable inventor based in Southampton, GB. He has made significant contributions to the field of antenna technology, holding a total of 3 patents. His work focuses on advanced methods for signal processing and multilateration systems.
Latest Patents
One of Brandwood's latest patents is titled "Unwrapping of phase values at array antenna elements." This patent describes a method and apparatus for unwrapping a set of phase values observed for an incoming signal on a phased array antenna. The process involves creating a first data set from the differences between values observed on adjacent elements in the array. A second data set is formed from the differences between adjacent ordinates in the first data set. The values in the second data set are rounded to the nearest whole multiple of one complete cycle before reversing the differencing process to provide unwrapped phase values.
Another significant patent is "Apparatus for multilateration and method." This invention addresses the positioning of an aircraft in a boundary zone between two adjacent multilateration systems. The controller in one system receives Time Difference of Arrival (TDoA) data from the controller in the second system. By using TDoA data, the timings of the two systems do not need to be synchronized, allowing for accurate multilateration to determine the aircraft's location.
