Because of the high maintenance needed to monitor and filter spammers from the RF Cafe Forums, I decided that it would
be best to just archive the pages to make all the good information posted in the past available for review. It is unfortunate
that the scumbags of the world ruin an otherwise useful venue for people wanting to exchanged useful ideas and views.
It seems that the more formal social media like Facebook pretty much dominate this kind of venue anymore anyway, so if
you would like to post something on RF Cafe's
page, please do.
Below are all of the forum threads, including all
the responses to the original posts.
Post subject: Doppler radar accuracy

If speeds in space one day get up to a significant
fraction of the speed of light, the relativistic
Doppler radar solution becomes:
= (1+v/c)/(1-v/c) - 1, which reduces to
v is very much smaller than c and v is an 'opening
Will someone please tell me the
velocity accuracy of good present day Doppler radars?
I would like to work out how fast relative velocities
in space must become before the error of the radar
equals the error of the low-speed approximation
