Research into the Influence of Millimeter-Wave Antennas on Direction Finding Errors by Phase Method
Известия высших учебных заведений России: Радиоэлектроника, 2023 Introduction. Direction finding errors degrade the performance of any direction finding system. In the case of a phase direction finder, the cause of errors, among other things, is related to the non-identity of the receiving channels.
