What are limitations of RADAR ?

DEIONISATION DELAY:

A small delay occurs in the TR cell between the completion of TX & Receiving. A delay of 0.5 microsecond would increase the minimum range a further by 7.5 mtrs.

THE VBW +THE HEIGHT  OF THE SCANNER MAXIMUM RANGE:
  • Height of the scanner increases the scanner , the increase of range.
  • Power of the set, marine radar set transmits around 25 to 60 kwt.
  • Wavelength: 10 CMS have extended range as compared to 3cms
Pulse Repetion Frequency

Pulse Length: Long pulses ensures better maximum ranges than shorter pulses cause , Long pulses  have more wavelength in them.

VBW/HBW: The narrower the beam width the greater the directional concentration, increases the range.
