Ok all, so based on what I know of folk and what I got briefed on by the person who does these.
We have three places to start and understand.
@Hell hound
The sim was built for doing Air Combat limited to the late 80's. Although it will do more, it does not know anything other than basic values.
Let start with the Radar of the Erieye for e.g. ..then we'll move onto correct the Radar systems of other aircraft that you can do.
For reference
This is the one for the E-2C Hawkeye

RadarType=
On this line, you set either AIR_INTERCEPT or RANGING depending on whether the aircraft has an airborne intercept radar or just a gun-ranging radar. If you select RANGING, you don't need to enter any of the other radar parameters below. EDIT: You can also leve this line blank (RadarType=) if the aircraft has neither an air intercept nor a gun-ranging radar.
RangeUnit=
Sets the unit of measure you will use in the remaining parameters. Use NM for nautical miles or KM for kilometers.
RadarAzimuthLimit=
RadarElevationLimit=
These lines set the maximum elevation (vertical) and azimuth (horizontal) search limits of the aircraft's radar. Measured in degrees.
RadarSearchTime=
RadarSearchRange=
RadarSearchStrength=
SearchTime is the time (I believe in seconds) that it takes the AI to 'notice' a target on its radar when it comes within range. SearchRange is the maximum range at which the AIs radar can detect targets in search mode. SearchStrength is an abstraction of the 'power' of the radar unit which can range from 01 to 100 (or possibly higher).
RadarTrackTime=
RadarTrackRange=
RadarTrackStrength=
These settings are similar to the Search settings above but apply when the AI switches from Search to Track mode on a target.
RadarSearchFreq= This is the frequency the radar operates in, NO AESA can truly be simulated in this besides increased scan speed.
Radar Search CW= Continuous wave illumination.
VisualBlindArc=
VisualRestrictedArc=
These define the 'blind spots' the AI has to deal with when attempting to acquire targets visually. Use clock references. For example, if an aircraft has no vidibility to the rear, set VisualBlindArc=6. If, in addition, the aircraft has poor visibility in its rear hemisphere, set VisualRestrictedArc=5,7. You can modify these by adding H for high or L for low. For example, VisualBlindArc=6L means the pilot is blind to his 6 o'clock low, but can see his 6 o'clock and 6 o'clock high without interference.
MaxVisibleDistance=
The maximum distance in meters within which the aircraft is visible to the naked eye.
HasRWR=
Defaults to FALSE, set this to TRUE if the aircraft is equipped with RWR equipment. Allows the AI to be aware when emitting radars are present.
Based on this, look at the figures for the Erieye and then try to fix what you think might be wrong.
