I have a feeling you can find some usable ideas in the design of MIR hardware.

google on MICROPOWER IMPULSE RADAR (MIR)

" MIR uses $10 of off-the-shelf components to outperform conventional radar and sensor equipment"

"Through sampling, a precise equivalent time measurement can be made at picosecond accuracy. Short-term jitter on the dipstick is kept to 50 fs as a result of averaging and of the CMOS technology's low noise."
