Question(s)

hi. beginner here.

i want to ask does the 4 antenna input terminals offer an option of DC output (~3.3 V to 5 V) to turn/power on LNA in the antenna?

There's no bias tee in the current KerberosSDR i'm afraid. Active devices need to be powered externally.

thank you.


is there any specific reason for the sampling rates to be 2.56 MSPS for passive radar and 1.0 MSPS for direction finding?

For PR you want the widest bandwidth possible (assuming your illumination signal is that wide too) to get the maximum resolution possible.

For DF the bandwidth doesn't matter too much, a smaller BW just reduces the processing power needed.
