Please, forgive me if I am not understanding this properly, but the signal sent by radar is an electromagneit wave (radio signal) and therefore it travels with a velocity equal to 300.000 Km/sec. It takes just a few microseconds to travel several kilometers... Therefore the radar sends the signal and gets it back in microseconds... the delay is really negigible !

Is SH5 currently modelling a delay of a couple of seconds for the radar signal ? That would be completely wrong !

Can you explain it, please?
