What is interesting, I have been seeing a lot of talk, and also snippets of a bigger tech manual showcasing the timing that is specificly between the radar and the SPO-15 so they will be in sync.
Especially to avoid interference of the radar and the SPO-15, and I have not been seeing any information so far that the radar completly cuts off the frontal lobe of the RWR.
Only interference that could happen what is a maintenence issue, hence why the sync is needed.
Not a RWR design flaw, such as like this currently.
When installed into aircraft, SPO-15 is connected to the radar with a sync blanking line which makes SPO ignore own radar when antennas catch radars sidelobes or structural elements pass the signal.
What makes complete sense in the matter.
This cut off implementation makes the SPO-10 look superior since even that has sync lines.
