How many channels does a monopulse receiver have for angle determination?

• A. One
• B. Two
• C. Three
• D. Four

Answer: (C)

Monopulse angle measurement uses a sum channel plus two difference channels to locate a target in two dimensions. The two difference channels provide angular error signals for azimuth and elevation, giving you two independent measurements of angle. The sum channel serves as a reference to normalize those signals and stabilize tracking, especially against range and amplitude variations. So, you end up with three simultaneous channels used for determining the target’s angle: the sum channel and the two difference channels.
