Step 1

  • About the Radar and Radar Band

RADAR is an abbreviation for RAdio Detection And Ranging. A system used for detecting and locating the presence of objects like ships, vehicles, aircraft etc. by radiating electromagnetic signal in space is known as the Radar system.

Basically, radar is used to collect the information related to the object or target like its range and location by radiating electromagnetic energy and examining the echo received from the distant object.

The radar band refers to the frequency range in which the radar emits radio waves. The unit of measurement is Hertz (Hz). For the sake of confidentiality, letters were used to indicate a certain frequency range during World War II. Because it is a paragraph by paragraph, the translator’s translation is vividly translated into bands.

The operating frequency range of most radars is 30 to 300,000 MHz, and the corresponding wavelength is 10 meters to 1 mm.

Step 2

  • The radar band

Generally:

P band  230-1000 MHz

L band 1000-2000 MHz

S band 2000-4000 MHz

C band 4000~8000 MHz

X band 8000-12500 MHz

Ku band 12.5~18 GHz

K band  18~26.5 GHz

Ka band 26.5~40 GHz

The above-mentioned bands are still in use today. With the continuous advancement of technology, the band used by radar is also expanding, such as the terahertz band.

 

  • Step 3 Other Microwave band:

L band 1 to 2 GHz Q band 30 to 50 GHz
S band 2 to 4 GHz U band 40 to 60 GHz
C band 4 to 8 GHz V band 50 to 75 GHz
X band 8 to 12 GHz E band 60 to 90 GHz
Ku band 12 to 18 GHz W band 75 to 110 GHz
K band 18 to 26.5 GHz F band 90 to 140 GHz
Ka band 26.5 to 40 GHz D band 110 to 170 GHz
