[passive radar] 4 channel coherent receiver needed

[Szilandras]

Hi,

I am looking for an SDR with 4 receiver channels besides KerberosSDR for passive radar applications.

We are already using the Kerberos in the FM band, but we would like to change our home-made receiver for an SDR in the DVB-T band.

I looked at LimeSDR, but as it turns out it can only receive on 2 channels at the same time.

If anyone know about any product that could be useful, please dont hesitate to tell me

Would SDRUno or Hack RF both of which support synchronizing clocks in multiple SDR's satisfy your needs?  If they all run on the same clock - I should think you will be able to manage diversity and phase detection.
