What describes Lobe Switching in scanning types?

• A. Circular Scan
• B. Raster Scan - 'Snake'
• C. Conical - Fire Control
• D. Lobe Switching - multi use, 4x conical

Answer: (D)

Lobe Switching means the radar switches between several fixed radiation lobes to determine where the target is, rather than sweeping a single beam through the area. By comparing the signals from multiple lobes, the system can deduce bearing and keep the target tracked. This approach is often implemented as a multi-lobe setup, such as four lobes arranged in a conical pattern, which is what “multi use, 4x conical” describes. The other scanning types describe moving a single beam in a circular, raster, or conical pattern, not switching among multiple lobes, so they don’t capture the essence of switching between lobes for bearing information.
