![]() In an nutshell, AESA= Active Electronically Scanned Array- composed of elements with T/R modules integrated to the individual element. PESA= Passive Electronically Scanned Array- T/R is done by TWT tubes not integrated to the elements. AESA is more capable, elements are frequency agile and system uses LPI principles. Beam can be rapidly steered and multi task. PESA hass steerable beam, but all elements operate on a single frequency and no LPI modes. PESA is jammable by saturating TWT tube. AESA is not jammable, since elements can operate on multiple frequencies.

I will give you examples for fighter aircraft.
The US has AESA radars for 5 fighters, F-16 (AN/APG68(v)9 or AN/APG 80), F-15 AN/APG 63(v2)), F-18 (AN/APG 79) F-22 (AN/APG77), and JSF (AN/APG 81). These are all fairly new, and not all of the older AC have them. Basically, everything uses passively scanned arrays. Elta (Israel) has developed an AESA radar, the EL/M 2052 that is aimed at the Mirage and Sukhoi market. The Europeans are working on one, the AMSAR, which will go in Typhoons, probably the Rafale, and whatever else. Phazotron (Russia) has developed one that was targeted for the Pak-fa, but it's future is still in question due to funding. |

Well, all of the AC have different size fuselages, and you want the biggest antenna you can fit. The APG63 and APG68 are first generation AESA, and based on previous versions of those radars- the APG77, 79, and 81 are second gen, and use common components. The JSF radar is based on the F-22's, it just has fewer elements and no side arrays, 1500 elements rather than 2200.
I think the EL/M 2052 will prove to be a very good radar. |

Does anyone know if the indian airforce is pursuing this radar that Israel made. It would be a really good idea and they already are getting quite a few things from Israel because their technology is really good. |
