Class Information
Number: 342/427
Name: Communications: directive radio wave systems and devices (e.g., radar, radio navigation) > Directive > Beacon or receiver > Direction-finding receiver only > With self-orienting antenna pattern > Monopulse or pseuodo monopulse tracking antenna type
Description: Subject matter wherein tracking of the signal source is accomplished by comparing overlapping pattern or lobe signals received by the receiver antenna to determine any discrepancy between the direction of the signal source, and any discrepancy is reduced to pointing error signals used for correcting the pointing direction of the antenna.
