Abstract:
1. A method comprising: splitting a signal into multiple portions corresponding to elements of an array; coding and phase adjusting the multiple portions of the signal to form phase adjusted, coded portions of the signal by coding each portion of the multiple portions with a different code and by applying phase adjustments associated with the corresponding elements of the array to the portions; transmitting the phase adjusted, coded portions of the signal via the corresponding elements of the array; receiving radiant energy at an element at a receiver side of the array, wherein the radiant energy corresponds to the phase adjusted, coded portions of the signal; decoding the coded portions of the signal to form decoded signal portions; adding the decoded signal portions to form a received signal; digitizing the radiant energy to form a digitized radiofrequency environment; generating multiple copies of the digitized radiofrequency environment; and applying a different phase adjustment function to each copy of the digitized radio frequency environment to generate multiple complete received signals, wherein each of the multiple complete received signals is associated with a different direction.
