Mutual Over-The-Air Synchronization of Radar Sensors

Over-the-air synchronization of radar waveforms can be used to achieve better interference suppression and enable radar-based communication. Within this initial study, a reformulation of the Kuramoto model is presented, which allows to synchronize the pulse repetition frequencies of two pulsed radar systems. To investigate the applicability of this approach, a simulation model was implemented and tested with various parameter sets. It can be shown that under certain circumstances, the pulse repetition frequencies converge to the same value and thus allow the radars to perceive their interferer as a single echo along range and Doppler.
