Abstract
An array of antennas is sequentially sampled by digital commutation means provide a synchronous display of a synthesized antenna array pattern of reception on a cathode ray tube indicator. The commutation means and digital means for generating sine and cosine signals operate from a common oscillator source. Digital means are provided to advance or delay the phase relation of the pattern or of a strobe line with respect to the CRT sweep to effect rotation thereof into azimuthal alignment. Automatic bearing readout is digitally accomplished when alignment is achieved.
