[UK-CONTEST] Radar Reflections

[Ken Eastty]

    *


Certainly size matters however the list on Flight Radar 24 of aircraft 
not yet fitted with ADS-B includes some Boeing 737-200, 747-100, 
747-200, 747SP, M D DC-9,  MD-8x  MD-9x & Most military aircraft. At 
present fewer big jets registered in the US are fitted. I know that the 
big jets out of RAF Brize Norton fly over here but never show up on 
virtual radar.
Giles flew a reconstruction of the Watson Watt radar experiment in 
something much smaller than the big gets, I think that it was quite 
successful Giles??

> Yes, you're correct, but size matters when it comes to the volume of any reflective entity that is useful for contest stations to take advantage of to make contacts.
> Invariably, an aircraft not required to be fitted with ADS-B will not be anywhere as large as your typical commercial jet so would produce minimal returns, if any.
> Consider the visual size of a 747 or 737 on the ground, then overhead at 11km away, then what it would be 250km to 300km away to work stations 500km to 600km away.

> We're hitting something very small to start with at those distances so a turbo-prop or very fast moving military jet would be of insignificant benefit.
