An alpha scan radar scans how many degrees?

Explanation:
Alpha scan radar is designed to provide complete azimuth coverage by sweeping the beam all the way around the aircraft. That means the beam rotates through the full 360 degrees, scanning every direction in the horizontal plane. This full-circle coverage is why the correct answer is 360 degrees. Other extents like 90, 180, or 270 degrees leave sectors unscanned and create blind spots where targets could be missed. With a 360-degree alpha scan, you maintain awareness of signals around you, which is essential for navigation and situational awareness.
