In MSSR terminology, what is the center of the main radar beam called?

• A. Boresight
• B. Centerline
• C. Phase center
• D. Peak location

Answer: (A)

The center of the main radar beam is called the boresight. This is the reference axis along which the antenna’s strongest radiation travels and where the beam’s central line sits. In MSSR, the boresight serves as the primary direction for aiming and for interpreting bearing on the display—the line through the middle of the main lobe. Centerline is a more generic term that can refer to the physical axis of the antenna rather than the actual beam center. Phase center relates to the origin of the phase fronts in an array and can vary with frequency and angle. Peak location merely describes where the power is highest, not the defined reference axis. So boresight is the precise term for the center of the main beam.
