[Milsurplus] Navy space radar stn.s

Well, I can honestly say I never expected my email thread to end up on FAS.
Since then I've done some sporadic listening on 216.98mHz and heard the
pings as objects pass through the fence.

It would seem like 4-5 amateur interferometers synchronized with atomic
clocks (GPS with 1pps most likely) could do some interesting work with it.
It might even be possible to do location off 4-5 synchronized stations.

IIRC, you have 4 components to work with:

    Start time of reflection (ping)
    Duration of ping
    Strength of ping
    Doppler of ping

    The doppler should give you the relative motion of the object, the
strength should give you and idea of the total RCS, and the duration the
ping should give an idea of the length of the object along the axis of
motion through the fence.  By syncing the start times among several stations
you would have a TDOA DF rig.

    Any other thoughts or am I way off base????
