Module 13. Aircraft aerodynamics, structures and systems

To improve the image or picture when using the WRX (weather radar receiver)

  • use longer bursts
  • use shorter bursts
  • scan at a lower rate

Explanation

Using shorter transmitted pulses (bursts) improves the weather radar's range resolution, so closely spaced returns are displayed as separate, sharper targets. Longer pulses smear adjacent returns together, degrading the picture; shorter bursts therefore give a cleaner, better-defined image.

Jordi asking:

i think this is wrong my notes from my academy say 'scan at lower rate" .
