Abstract
A system and method synchronize two radars by transmitting a linear frequency modulated first signal from a first radar, receiving a first reflection at the first radar based on the first signal, transmitting a linear frequency modulated second signal from a second radar, and receiving a second reflection at the second radar based on the second signal. A fast Fourier transform is performed on the first reflection and on the second reflection to obtain a first frequency-domain signal and a second frequency-domain signal. The first frequency-domain signal and the second frequency-domain signal are converted to the time domain to obtain a first time-domain signal and a second time-domain signal. The first time-domain signal and the second time-domain signal are processed to obtain a time difference in transmission of the first signal and the second signal, and the two radars are adjusted based on the time difference to synchronize subsequent transmissions.
