Need advice / tips modding radar: Sweep style and 160 degree arc

[Eagle114th 723]

Hello everyone!

I am working on AN/APS-31, and here is a brief information:

AN/APS-31 is an X-band search radar containing many of the special features of design and operation contained in AN/APS-15. Its antenna scans through a forward-looking field of view producing a scope presentation of a 160° V on a PPI-type scope.

What I am trying to achieve is to turn A-4 radar into this kind of radar with 160 degree sweeping



I am current stuck on trying to turn radar into this style.  I am using avionics.60.dll and here is codes

NOTE: I am using A-4E avioincs as base to start with, so I am modifying the codes to turn them into PPI and 160 degree scanning.

[AvionicsData]

RangeUnit=NM
RangeSetting[1]=10

ImageFadeTime=1.0
SweepIntensity=1.0
StrobeIntensity=0.8

[RadarDisplayGround_Map]
PPI=TRUE
Symbol[01]=PPI_SWEEP
Symbol[02]=HORIZON_LINE

[RadarDisplayTerrain_Avoidance]
PPI=TRUE
Symbol[01]=B_SWEEP
Symbol[02]=HORIZON_LINE

The result is that the radar sweep stays at bottom of the radar scope, instead of moving to the middle, therefore I get mixed of upper and lower scanning on one screen:

(Notice that the PPI sweep disappear due to going beyond the botom of radar scope)

What else should I do to enable 'true' 160 degree radar scope?

Thank you
