Abstract: The present disclosure relates to a method for synchronizing time alignment in a multi-channel radio frequency receiving system, the method including injecting an amplitude modulated reference signal into each channel in the multi-channel receiver at a location associated with each antenna input. Further, the method includes the steps of detecting a position of the reference signal within a time sample window and determining propagation time difference between each channel within the receiver electronics. Further, the method includes the steps of determining adjustment parameters, for synchronizing time alignment, for each channel and adjusting the channels in the time domain in accordance with the determined adjustment parameters of synchronization for each channel.
