What frequency range do most radar receivers commonly operate within?

The common operating frequency range for most radar receivers is typically between 30 MHz and 300 GHz. In the context of the choices provided, the option indicating 30 MHz to 60 MHz accurately reflects a segment within this broader range, particularly relevant for certain radar applications.

Radar systems are designed to operate efficiently at various frequencies depending on their intended purpose, with many lower-frequency radars functioning effectively within this range for applications like surface search and some air traffic control systems. The specific frequency range helps in minimizing atmospheric attenuation and enhancing target detection capabilities.

The selection of this range emphasizes its relevance in radar technology, designed to optimize performance based on the balance of wavelength, required resolution, and the strengths of propagation.
