Reliable and Flexible Simulation of Angle of Arrival (AoA)

Published by: Rohde & Schwarz

Radar warning equipment is installed in all types of airborne platforms such as airplanes, helicopters, etc., and in naval or ground based platforms. This equipment protects the platforms and all personnel operating the platform such as pilots, naval staff, etc.
The purpose of the radar warning equipment is to detect, measure and identify radar signals and to provide a warning to the crew so that available countermeasures can be taken, or manoeuvres carried out. It is also mandatory to have direction finding (DF) capabilities to identify the angle of arrival (AoA) of a signal.
For DF purposes, platforms have multiple antennas installed at different positions. After down conversion to an intermediate frequency (IF), the received signals are fed to a multichannel radar warning receiver and processed in a central computer that evaluates the amplitude, phase and time difference between the individual received signals. Typical DF techniques are amplitude comparison (amplitude monopulse) and interferometry.
