Variants
AN/APG-65: Base version. Installed on F/A-18A/B/C/D before Lot 16(1992).
AN/APG-65(V)2: Modified version for AV-8B Harrier II Plus. Has smaller antenna due to the radome sizes, which results in 10% lower performance.
AN/APG-65GY: Modified version for F-4F ICE and F-4E AUP.
AN/APG-73 RUG I: Phase I upgraded version, using modules from AN/APG-70 for 7~20% longer detection range and enhacned ECCM, etc. Installed on F/A-18C/D since 1992, and later retrofitted to earlier F/A-18C/D and some F/A-18A/B.
AN/APG-73 RUG II: Phase II upgraded version with improved air-to-ground capabilities. Installed on Lot 20 F/A-18C/D and F/A-18E/F.
AN/APG-79: AESA radar based on AN/APG-73. Installed on F/A-18E/F aircrafts with improved forward fuselage called ECP 6038, and EA-18G.
AN/APG-79(V)4: Scaled-down APG-79 for F/A-18C/D. The first American airborne AESA fire control radar featuring gallium nitride technology.
MSD-2000: Improved APG-65, proposed for EFA programme.
Raytheon Advanced Combat Radar: Scaled-down APG-79 for F/A-18C/D. Initially offered for the U.S. Marine Corps’ F/A-18C/D radar upgrade, but eventually replaced with APG-79(V)4.
Currently as of 2.29.0.7
Beam width in elevation is wrong
Range scale is wrong
Azimuth scan zone is 140/60/20, should be 140/90/45
Bar Scan should be 1/2/4/6
When comparing the signal processors, the APG-73 has more than eight times the throughput of the APG-65. This results in higher doppler resolution and better ECCM performance.
Hello ! I was wondering why the AV-8B+ doesn’t have the same amraam path indicator as the F-16C for example and I was also looking for stats on how many fox-3 the radar could guide at the same time (the radar correction channels)
Do you have any kind of answer to those questions ?
(My main guess was that the radar was a bit too old for those systems but I might be wrong)
I have no clue about the missile path indicator. APG-65Q is an old radar compared to the more advanced variants like APG-73, but that may not be related to this issue.
For the radar correction channels, currently it is unlimited.
Though it’s stated that new waveform is required, compatible for the sparrow.
Might be due to the apg-65 using Range Gated HPRF (in between MPRF and HPRF) which isn’t optimal/compatible rather than a normal HPRF STT the apg-63 used, which would have been close to 40-50% duty ratio and higher PRF. To get maximum energy for the seeker and prevent ambiguity issues.
Either way, the radar system switches to PDI( which is HPRF ) when the sparrow is selected and the target is within 120% Rmax. Exactly how the apg63 does in the F-15’s -34 but no indication of PDI mentioned in any document from this type.
So for the F18, it doesn’t change exactly when the missile is fired but much before so no indication when a missile is launched. Exactly how the apg63 does in the F-15 -34
APG-65s are missing (no surprise) along with many others TWS in HPRF
Spoiler
And to launch a sparrow you don’t need to go STT then initiate the launching, the radar itself with transfer to STT and fire the missile, saving a second or two in reaction time
Should the AV-8B+ have datalink and multiple missile guidance? The report suggests the -65 has the TWS and thus the guidance capability like the F-14 does, but it also has the: “Priority Target” disclaimer, which might have been for Aim-7 purposes.
