Not shure how AESA hurtht he Typhoon in the SIngapore competition, ALL the rumours circulating ssaid they were impressed with the radar, and that the main obstable was the development timeline being not up to scratch, as was the case in Korea, lack of AESA was not mentioned in either. In terms of the A2g role,w hilt the Captor does not allow simulataneous a2a and a2g, from what i have heard it is pretty close to being ( the change between the two is so quick), in terms of a2g capabilities perhaps could point out the MAJOR deficicies Captor has compared to AESA ( as i understand it, it lacks terrain following mode (but not terrain avoidance), but you clearly know more so please elaborate....

Let me take a minor stab at it. The only remote point that AESA would have over the others is its ability to shift in multiple directions within a thousandth of a second. The elements in the AESA is able to oscillate in its search pattern, but like all radars it is limited by its computational processing limits and software. Most of the data is discarded by the processing filters simply because it cannot cope with it all at once. While its true that AESA can scan both a2a and a2g simultaneously there is a strict limit to its ability to handle the information stream. The reason it cannot be used for simultaneous terrain avoidance, terrain following, and weapons roles is that the terrain following capability requires too much raw crunching all by its lonesome. The terrain following radars use carefully timed rosetta scan patterns to ascertain the exact shape of the terrain both below, ahead, and when possible it has to try to gain vantage points that are simply out of the field of view and therefore the information is anticipated in its algorithm. The AESA radar would need a hardwired multithreaded capability that it just doesn't currently have. The other less demanding roles can therefore nicely fit within its current software and processing limitations. It will happen, it just will take the developers a long while to work out the structure of the software. These things just don't grow on trees.

Thanks for your 2 links DA . I was wrong about the Singapor deal . Cheers .

MadRat , it 's not correct to say that AESA ~or PESA~ Radars cannot interleave AtA and AtG fonctions . As an exemple , RBE2 ~which is only a PESA Radar~ allow Rafale to undertake a terrain-following flight and mapping the ground in real time WHILE simultaneously tracking up to 8 enemy Aircrafts . RBE2 's CPUs perform 1.2 billion operations per second . Cheers .

I must of worded my response in a way that sounded like that? I don't remember sating it couldn't do that. The AESA uses virtual bars to get its "picture" drawn within the computer, therefore its able to many functions simultaneously by using filters to only nab the inputs that are warranted.
