Class Information
Number: 342/149
Name: Communications: directive radio wave systems and devices (e.g., radar, radio navigation) > Determining direction > Monopulse
Description: Subject matter including the use of a radar technique in which the angular location information of a source or target object is derivable from each pulse or signals received simultaneously in two or more antenna beams, i.e., sum and difference channels in the receiver compare the amplitudes or phases of the antenna outputs.
