What is the frequency range of the Primary Surveillance Radar (PSR)?

The frequency range of Primary Surveillance Radar (PSR) is primarily designed to operate within specific bands to ensure effective tracking and identification of aircraft. The correct frequency range for PSR typically lies between 2700 MHz and 3000 MHz. This range allows for optimal performance in detecting and measuring the distance to aircraft, utilizing radio waves.

Choosing the frequency 2700-2900 MHz signifies the confirmed operational limits for PSR, which balances good target detection capabilities with the necessary sensitivity and resolution for air traffic management. Frequencies within this range help mitigate interference from other radar systems while providing reliable data.

The other options suggest either broader or narrower frequency ranges that do not accurately match the established standard for PSR, thereby making those selections less appropriate for this particular question about radar operations.
