Primary radar uses reflected radio signals to work out how far away am a/c is. What equation does it use to measure distance of A/c
Distance = speed x time divided by 2
How long is a radar wavelength
1mm to 100cm
If a higher frequency has a shorter wavelength what does this mean for the range
Less range
What length wavelength does a primary approach radar use
3-10cm
What length wavelength do you need for a primary area radar
23-50cm
What are the 2 types of clutter
Ground clutter
