RECEIVING SYSTEM WITH ELIMINATION OF DISTURBANCE WAVE

PURPOSE:To faclitate the easy elimination of the disturbance wave, by setting three receiving antennas to ensure the same phase and same amplitude at an equal distance to the desired wave and then synthesizing the received signals. CONSTITUTION:Antennas 1a-3a are set with an equidistance (d) in orde...

description PURPOSE:To faclitate the easy elimination of the disturbance wave, by setting three receiving antennas to ensure the same phase and same amplitude at an equal distance to the desired wave and then synthesizing the received signals. CONSTITUTION:Antennas 1a-3a are set with an equidistance (d) in order to secure the same phase and same amplitude at an equal distance to a desired wave 11. In case a disturbance wave 12 and the wave 11 are received with an angle theta formed between them, the receiving phase difference of the wave 12 is different between antennas 1a/2a and 1a/3a. The degree of control is calculated from the relation between the synthesized output of the antennas 1a and 3a plus the disturbance wave component of the antenna 2a. Based on this degree of component, the amplitude is controlled for the output of the antenna 2a. At the same time, the output of the antenna 2a receives a phase shift of 0 deg. or 180 deg. in accordance with the arriving angle theta of the wave 12 and is synthesized with the outputs of antennas 1a and 3a. In such way, the disturbance wave can be eliminated.
