In your screenshot, the target aspect is shown on the HUD ( the small triangle on top of the circle) and on the radar, the target has a small stick pointing in the direction of movement.
There is no digital aspect readout though on HUD or radar, and thats correct afaik.
For knowing who is who on the radar, all contacts show as rectangles initially, and after several sweeps the friendly aircraft contacts should change into a circle - but the radar mod shown in your picture isnt mine, so I dont know if that feature has been implemented.
EDIT:
Also, after the IFF function separated the contacts into friendly and enemy contacts, you can only select enemy contacts
with your radar cursor.
I have made a APG-65 for A/B model Hornets and have the IFF feature for both Search and TWS modes
