correct as is High Flying F-18 Unable to Track Contacts At Low Altitude Regardless of Aspect

[DCS FIGHTER PILOT]

    As you can see in the tracks, I loose track of a hot Su-33 at around 10 miles that is flying much lower than me. In the second track, you can see that I cannot even bug a Jf-17 that is low flying and hot on me. Needless to say, these targets are not notching and I see no reason why I cannot see them on my radar.
