Radar Applications
Radar applications by frequency:
HF (3 to 30 MHz)
The very first British radar system ‘chain home’ used the HF band, but it was soon realised that these frequencies were becoming too crowded with other users and they suffered from too much external noise for serious use.
The HF band is still good for long-range ‘over-the-horizon radar’. (See ‘examples of radar systems’)
VHF (300 to 1,000 MHz)
Used for ‘Military airborne early warning (AEW) radars. UHF is good for …showed first 75 words of 466 total…

Laser radar
Laser radars that operate at infrared and optical frequencies also suffer from high sensitivity to the atmosphere and the waves tend to react in all manner of odd ways especially in bad weather. Although they have been tested for distance measuring in surveying and for precision range finding in weapon control, their main advantage would be probing the nature of our Earth’s atmosphere from a spacecraft (maybe even other planets).
