Systems, methods, and computer-readable media for synchronizing oscillators. A system can include a plurality of oscillators comprising at least a first oscillator and a second oscillator. The system can also include a plurality of antennas comprising at least a first antenna and a second antenna. Further, the system can include a first oscillator synchronizer coupling the first oscillator to the first antenna. The first oscillator synchronizer can be operative to perform a first synchronization of a first time base of the first oscillator to a second time base of the second oscillator based on a first mutual coupling signal. The first mutual coupling signal can represent a first interaction between the first antenna and the second antenna.
