    Any external PA you can proposal to increase the limited output? For GPR purpose, like 3~5m deep under ground...

    thanks bro. the target objects could be cables/PVC pipes/concret iron...

    for vmmk-3803, seems the low side of passband is too high(>3GHz?), I think the proper PA at TX end should be 0.5G to 6G. what's your advice?

    Noted your old device NAV6100 might suitable for wall-throug imaging. Could it be possbile to leverage its RX to sample the reflected signals from OTHER impulse generator with big power?

    Syncing our receiver with other TX sources is not very simple. It has to be synced with precision in the pico-second scale. Our system works by doing lots and lots of oversampling where the transmitter and receiver is in sync and this synchronization is handled on-chip. In addition you would probably want lower frequencies that where we operate which is in the 3.5 to 10GHz range. Ground Penetration Radars typically operate below 1GHz.
