"Radar" comes from RAdio Detection And Ranging. If it didn't use radio it would be called something else.LIDAR (LIght Detection And Ranging) is laser instead of radio. That uses light.

The COHO (Coherent Oscillator) in an MTI (Moving Target Indicator) radar typically uses a local oscillator frequency that is twice the radar's operating frequency. This frequency is used in the radar's mixer stage to enable the detection and tracking of moving targets.
"Radar detection system: madam rotor" is a palindrome for detection system using radar waves.

Radar receivers have to be tuned to the precise frequency of the transmitter, in order to get the best detection and thus the best picture. The transmitter generates microwaves from a device called a magnetron. The exact frequency can vary with age and temperature. To pick up the echo generated from the pulsed microwave, the receiver is able to be tuned, to allow for differences in transmitter frequency. The control on the radar receiver display, called 'tuning', actually alters the receiver frequency, not the transmitter frequency.

Increasing the pulse repetition frequency can improve target detection and tracking capabilities. However, it can also increase the likelihood of signal clutter and decrease maximum unambiguous range in radar systems. Balancing these factors is crucial to optimizing radar performance.
Radar can operate at frequencies as high as the terahertz range, which is typically between 300 GHz and 3 THz. These high frequencies allow for higher resolution imaging and detection capabilities compared to lower frequency radar systems.
