RADAR stands for Radio Detection And Ranging, and it uses microwaves to detect and track objects. Microwaves are a type of electromagnetic radiation with wavelengths ranging from 1 millimeter to 1 meter, which falls within the radio frequency spectrum.
Here's why microwaves are ideal for RADAR applications:
- Penetration: Microwaves can penetrate through certain materials like clouds, fog, and even some types of foliage, making them suitable for use in various weather conditions.
- Reflection: Most objects reflect microwaves, allowing RADAR to detect their presence and location.
- Wavelength: The relatively short wavelengths of microwaves provide high resolution, enabling RADAR to distinguish between objects that are close together.
