Can anyone please answer, if chinese engine is being matured and readied for block III then where does RD-93ma fit in the picture? Is it for block II?
customers will have options to use either.
So we won't see RD-93ma in block II?
There is no standarization as such that what RCS would the RADAR design look into.
I could be wrong , but all things being equal, PAF will likely go for the 93MA instead of the WS. The 93MA will have a lot more in common with the 93.
Regarding 'radar cross section' (RCS)...
The RCS figure is a 'fiction'. No, it does not mean anyone can make it up. It mean this value, while is a valid mathematical result attached to a body, said value is NOT constant but varies according to distance in relation to the seeking radar.
Can the F-22 have an RCS of 50 m2 ? Absolutely -- when it is a few meters from the seeking radar.
So when a body, be it the simple sphere or as complex as an aircraft, is reputed to have X meters/squared RCS, that 'X' is supposed to be accompanied by a distance from a seeking radar operating under a specific frequency range, or band, like the X band, for example.
If a radar have a maximum reach (range) of 100 km, using round figures for ease of understanding, then effective range is about 80-90% of that max. If a complex body is reputed to be 5 m2, then it begs the question of WHEN will that figure appears, inside that 80-90% range, or beyond ? So it could very well be that a complex body will be 5 m2 at 90 km. Or 10 m2 at 60 km. Or 20 m2 at 40 km. And so on...
Can a B-52 have an RCS of 1 m2 ? Absolutely -- when it is a few hundreds or even 1000 km from the seeking radar. So when will the B-52 have an RCS of 5 m2 ? May be at 800 km out.
Generally speaking, the more complex the body, the higher its RCS will be at any fixed distance compared to less and less complex bodies WHEN ALL BODIES ARE AT THE SAME DISTANCE.
EM wise, the F-22 is less complex a body than the F-16, even though the F-16 is physically smaller, because in radar detection, what is 'complex' and its degrees depends on these rules:
Control of...
- Quantity of radiators
- Array of radiators
- Modes of radiation
The F-22 just happens to be effective at obeying those rules than the F-16. It does not mean the F-16 and the B-52 somehow 'violated' those rules. It means they are LESS EFFICIENT at obeying those rules than the F-22 does, so in radar detection theory, physical complexity does not always equals to reception (or perception) complexity. That is why if we put the F-16 and F-22 at the same distance, any distance, to the seeking radar, the F-22 will have a lower RCS value. That is why radar engineers do not casually use any RCS figure as standalone but tries to accompany that figure with at least an operating frequency, if not frequency and distance.
Just mention the next, FC1 and F-10 avionics gap, the overall architecture avionics FC1 is more advanced than the F-10 instead of backward, and this is the advantage of FC1, such as electronic jamming systems FC1 is the most advanced than the F-10 are FC1 advanced cockpit design is significantly stronger than the F-10, but in a somewhat less subsystem FC1.Such as radar air search radar FC1 is 130 kilometers (three square meters target), the F-10 air search radar was 145 km (3 m2 target).In 2016, FC1-BLOCK2, new FC1 will install the whole operating system to more than four degrees, aerial refueling equipment, high-speed data link (data link FC1 than it is now much better), and so on
The source I have seen says 130km but does not give the reference RCS. In the video, the engineer does not mention radar radar.Sir the Most latest source for KLJ-7 confirms that it can detect a 3m2 target at 130km.

Can you calculate us at what range it would detect a 5m2 rcs target?

Whatever happened to Teja bhai, I mean the LCA Tejas
mamoo ap tu serious hi ho gaey hoGo to the appropriate thread and find out. This is not the place for discussing LCA.

thank you..I just found a lil while ago too n sorry...
