Title: James Joseph Fisher: Innovator in Multilateration Systems
Introduction
James Joseph Fisher is a notable inventor based in Romsey, GB. He has made significant contributions to the field of multilateration systems, holding a total of three patents. His work focuses on enhancing the performance and accuracy of signal reception in various applications.
Latest Patents
One of his latest patents is titled "Apparatus and method for determining receiver performance in a multilateration system." This invention involves grouping receivers into two categories to determine the position of a signal source, such as an aircraft equipped with a SAR transponder. The system generates predicted time of arrival values for a second group of receivers, which are then compared to actual arrival times. By analyzing the differences and their variations, the system can identify receivers that are operating with undesirable time delays.
Another significant patent is for a dual-polarized antenna. This innovative design combines two types of antenna elements on a planar substrate, featuring inter-engaging slots for assembly. The signal feeds are connected to the active parts of the elements at off-axis positions, allowing for a co-located arrangement of effective phase centers, which enhances performance.
