How about some simple countermeasures (for a future firmware release):
Blank, then transmit an equal length pulse (on a clear frequency, of

If it's anything like the Russian woodpecker, it likely transmits a
string of bits using a psuedo-random code in each "pulse', and the radar
RX can separate it's own echoes from fake ones.
That's got to be very difficult noise for any NB. My TS-850 has a NB
designed for the old Russian woodpecker, but I don't know how it works,
and that radar is gone now so I can't try it out. Maybe there's some
way to tailor the K3 DSP NB to the characteristics of the radar?
