Wavefront Simulator for Evaluating RF Communication Array Signal Processors.

reportActive / Technical Report | Accession Number: ADD016281 | Need Help?

Abstract:

A wavefront simulator that emulates plane wave propagation from multiple transmitting antennas is used to evaluate, in both a static and a dynamic manner, an array processor used in RF communications to determine the location of transmitting antennas and possibly to perform beamforming for cancelling the energy of an interfering transmitter. The wavefront simulator generates time delay signals, giving the appearance of being emitted from different transmitters or sources, and simulates those signals as being received by an antenna array associated with the array processor. The array processor utilizes the time delay signals to calculate, e.g., the angle of arrival of the signals from the emitting antennas.
