Instead of posting about F-16C/Ds radar as promised earlier i begin with F-15s radar and will follow the order as given in Janes Radar and EW 04-05 edition.
First i will cover american airborne fire control radar and then will move to russian followed by Italy, Israel, UK and Captor radar equipping EF typhoon. Being a student it will take me time to cover all of them so kindly bear with me.
Thales web link posted by himanshu is a much much better source of info for french radars than janes. I have compared the two together.
AN/APG-63(V) MMR ------------------ USA
1) PD system operating in I/J band
2) Gridded Travelling wave tube transmiteer w/ digital doppler signal processing and digital mode/data management.
3) Operates over wide range of pulse repetition freq., pulse widths and processing modes.
4) Planar array type I-band antenna carried on 3 axis gimbal system.
5) Radar info. digitally processed. 2 types of display.
---> One CRT display at upper left hand corner of instrument panel called Vertical Situation Display(VSD). VSD presents a cleaned synthetic display of computer processed radar video data with alphanumerics and symbols. VSD employed for long range, initial stages of interception.
---> Second is Head Up Display (HUD). HUD employed during actual engagements or close in encounters.
6) Main Control panel on Console of left side of pilot. Console carries 2 throttles & key radar operating modes located on them. 3rd location for radar control is aircraft control stick.
7) VSD shows target altitude, groundspeed, heading, range, aspect angle, closure rate and g-force. A satisfactory response to an IFF interrogation is also shown in form of a symbol.
8 ) Automatic acquisition switch on aircraft control stick enables pilot to lock radar on to targets within close in ranges. 3 modes used:
---> Boresight mode --- radar locks on to first target entering aircraft boresight as designated by the gun reticule on HUD.
---> Supersearch --- locks radar on to the first target that comes within the HUD field of view.
----> Vertical Scan --- locks radar on to the first target that enters elevation scan pattern normal to the aircrafts lateral axis.
9) Two variants
---> APG63(V)1 --- Designed for field retrofit to the F-15. Focuses on enhancing system performance, reliability (120 hrs MTBF), maintainability and supportability. Features
i) built in test[frequently to modular level]
ii) compatibility with both mechanically and ES antennas
iii) increased reciever/exciter signal to noise ratio,
iv)increased transmitter bandiwdth
v) increased processing throughput and increase processor memory.
System's operating modes -
iii) vertical scan
iv) auto gun
v) track while scan
vi) range while scan
vii) precision velocity update
viii) ground moving target detection
ix) high resolution ground mapping.
----> APG63(V)2 features
i) An AESA antenna.
ii) Improved Honeywell Env.CS.
iii) Integration w/ advanced BAE systems IFF.
iv) It is noted of taking full advantage of AIM 120 capabilities.
On a side note: Accoding to Janes sources APG63(V)2 has been fitted to 18 F-15C interceptors based at Elmendorf Air Base, Alaska with installation being originally scheduled to be completed by 2000.
Freq: 8-20 GHz selectable in I/J band.
Range: 161 km
Antenna: 3 gimbal axes, mechanical scan.
No. of LRUs: 9
Weight: 221 kg
Volume: 0.25 cubic m
MTBF: 60 hrs.
From an online article
There seems to be another variant APG63(V)3 which is also an AESA.

Raytheon makes nearly identical claims about the AN/APG-63(V)3 stating that is mostly an antenna replacement and that the back end of the radar set remains much the same. “What has made the difference in the design of the (V)3 variant versus the previous (V)2 model has been the use of next-generation tiles in the T/R modules, a benefit that we enjoyed from the crossover of the technology we developed on the AN/APG-79 for the F/A-18E/F. This makes the (V)3 about 240 pounds lighter than the previous generation model,” stated one designer.
