First don't trigger the SWR protection unless the forward voltage/power is greater than some threshold.
I did exactly this, only in hardware, for my current client project's AD5519-based VSWR protection circuit.?
I wired the forward power comparator and the VSWR comparator outputs so that both needed to be satisfied to shut down the amp.? Pots adjust the power and VSWR trip points? An SCR provides a latching function when triggered
