I say you don't know.

But suppose that this is true ,that it gives us?

The APG-77 has range 250-300km for a 1 m2 target in LPI it will be 4/5 or 2/3 ie 190 km .

Apg-81 can track target with RCS = 1m2 from 150 km in LPI, less than 40 km compared to APG-77

Now let's say that the technology LPI was improved - is it possible? Perhaps.

If 150km are 4/5 of max range, then max range=187km , If 150km are 2/3 of max range(ie technology not improved)

then max range=225km

This leads us to the conclusion that the radar Apg-81 is inferior in size and maximum power to radar APG-77 .
