Thanks for the explanation. but we don't know anything about radars of the plane's radar and frankly and only time will tell if they actually change the size of the nose, if not, then they must had brought the radars bit further back somehow?.
Then again, this plane is just a mock-up so I am sure the nose will be made bigger.
That does not mean we cannot make reasonably intelligent and accurate guesses based upon real physics.
For example, beam shape is determined by antenna shape, like this extreme example of a fan beam...
Beam shape is 90 deg from antenna shape and orientation.
Another real physics limitation is antenna dimensions directly and inversely affect beam 'tightness', in other words, the smaller the physical array/antenna, the broader the beam, and the more coarse these vital target resolutions:
- Altitude
- Speed
- Heading
- Aspect angle
The larger the antenna, the tighter the beam, as in 'pencil beam', and the greater those vital target resolutions.
Another problem with increasingly wide beam, especially with increasing distance, is called 'resolution cell'...
Definition: radar resolution cell
The volume of space that is occupied by a radar pulse and that is determined by the pulse duration and the horizontal and vertical beamwidths of the transmitting radar. Note: The radar cannot distinguish between two separate objects that lie within the same resolution cell.
So if you have a large round antenna to start, you will have scan with a very narrow or 'pencil beam', not a fan beam, and as distance increases from you, beam broadening over that distance will be less problematic when multiple targets are flying close to each other in trying to hide their true attack numbers.
This Ghaher 313 model seems to hint at a much smaller radar than tactically necessary. You cannot increase radome size without matching fuselage size to support it. Or you are going to have a very strange looking fighter, one with a bulbous schnoz.
What do you think of the stealthiness of this plane? do think it's shape is stealth?
Anyone can claim it is 'stealthy', but the truth can only come from isolated anechoic chamber testing, like what we do in the US...
Benefield Anechoic Facility - Wikipedia, the free encyclopedia
Benefield Anechoic Facility (BAF) is an anechoic chamber located at the southwest side of the Edwards Air Force Base main base. It is currently the world's largest anechoic chamber.

What 'isolated electromagnetic anechoic chamber' testing does is to literally seal a body from all possible EM signals from anywhere, even from cosmic background radiation (CBR). Then the body is bombarded with precise signals at very specific areas and all tests are analyzed to come to as technically true a radar cross section (RCS) value as possible. The results of these tests
WILL NOT be released to the public. Not even the retired F-117's RCS is known. Only guesstimated.
This complex issue of 'stealth' have been discussed at length here and I have presented the forum with many publicly available sources for everyone to verify for themselves.
So for important missions (for example killing an Al-Qaeda military commander), do they use the drone autonomously? Or is it piloted for these high-ranking missions?
Autonomy is for predictive flights, such as loitering to continuously monitor an area, or to fly to-from where the flight paths are not subjected to deviations. But when there are situations that are highly unpredictable, like a ground target's movement from his house to the outhouse then to the weapons shack then back to the main house, a human pilot takes over.
