a hybrid algorithm that combines Time-Difference-of-Arrival (TDOA) and Power-Difference-of-Arrival (PDOA) localization techniques

Description

the invention is a hybrid algorithm that combines Time-Difference-of-Arrival (TDOA) and Power-Difference-of-Arrival (PDOA) localization techniques in order to determine the position of a jammer/spoofer in a wider variety of situations. There are many cases where each one alone is not sufficient, and by combining them, each technique's strengths are emphasized. This invention also allows the future combination of other localization techniques including Frequency-Difference-of-Arrival (FDOA) and Angle-of-Arrival (AOA) as well as utilizing multiple frequencies.
