APG-70 это двадцатилетней давности апгрейд для APG-63 с расширением возможностей работы по наземным целям. Если уж сравнивать то с APG-77 или APG-79. Если только ктото найдет их вразумительные характеристики.
Aviation Week gives APG-77 range for 1 sq m at some 120 nautical miles
the APG-77 radar range has been reported by aviation week to be 125nm for a 1 m^2 target using the LPI mode..however that is taken using the basic ATF reqirement..the flight test data has shown the f/a-22 (production varient) to have a 5% advantage in the radar range over that ATF requirement..so the actual range is somewhere in between 125 and 132 nm which is roughly 200-210 km.
