Microwave Radiation in Radar Systems

Microwave radiation enables radar systems to detect objects with high precision across various weather conditions

Why are microwaves particularly suitable for use in radar systems compared to lower frequency radio waves?

Because microwaves can diffract around obstacles and follow the Earth's surface, extending radar range significantly. Because microwaves reflect strongly from the ionosphere, allowing radar signals to travel beyond the visual horizon. Because microwaves provide higher resolution and can penetrate atmospheric conditions like fog and rain better than lower frequency radio waves.
