cone-shaped area. The traditional solution to this problem is to use conicalscanning. In this system, the receiver is connected not to a single receiver
practical designs did not become possible until the introduction of conicalscanning and miniaturized vacuum tubes during the war. Anti-aircraft IR systems
Angle deception jamming is an electronic warfare technique used against conicalscanning radar systems. It generates a false signal that fools the radar
from a single signal pulse. Monopulse radar avoids problems seen in conicalscanning radar systems, which can be confused by rapid changes in signal strength
