What do you call propagation of a wave from one point to another by more than one path?

• A. Monopulse scan
• B. Scanning Method
• C. Multipathing
• D. Conical Scan

Answer: (C)

Multipath propagation describes a wave reaching a point via more than one path. In real environments, the signal can travel directly and also reflect off surfaces like the ground, water, buildings, or atmospheric layers. These multiple routes have different lengths and phases, so when the copies arrive at the receiver they interfere with each other—sometimes boosting the signal, sometimes weakening it, and sometimes creating ghost echoes or clutter in radar displays. This term specifically names the propagation phenomenon caused by multiple paths, rather than how the radar beam is steered. The other options refer to scanning techniques, not the way the wave propagates.
