Boresight
The boresight (BST) mode causes the antenna to cease scanning, move to the aircraft boresight line
(straight ahead), and stop. The first target (shortest range) to cross through the main beam is locked-
on to (acquired), and the track function begins. Boresight uses all MPRF and is good out to 10 NMI.
Pressing the AUTO ACQ/REJECT switch forward twice in less than one second selects boresight.
Long range boresight
Long range boresight (LRBST) acts exactly the same as boresight does. The only difference is that
long-range boresight uses interleaved PRF and has a range of 40 NMI. Holding the AUTO
ACQ/REJECT switch forward for longer than one second selects long-range boresight.
Track-while-scan
TWS modes provide a wide-angle coverage, multi-target detection and track capability. The TWS
modes maintain up to 10 target track files while continuing to detect and display up to 18 more (half-
intensity) observation targets.
According to the dark grey colour and CFT it is an F-15E.
These are the antenna covers for the TEWS system, which is a jamming/RWR system.
The more modern variant is called DEWS and now EPAWWS.
The antenna covers often vary in shape depending on the upgrades.
Your calculations are very strange
it is necessary to take the target detection range from RCS 1m2 and multiply by the root of the fourth power of the desired RCS
Not really. To make range a function of RCS you make everything else constant(as the only thing changing is rcs and conditions remain the same). You can use that constant-ratio to solve for the RCS.
Beta=(known range)/((known RCS)^1/4). Beta = (desired range)((desired RCS)^1/4)
\beta=\frac{\mathrm{R}{k}}{\sqrt[4]{\mathrm{\sigma}{k}}}
as transmit power remains, frequency etc, all those variable remain the same and the onyl thing changin is Range and RCS.
\beta=\frac{\mathrm{R}{D}}{\sqrt[4]{\mathrm{\sigma}{D}}}
If you are talking about the CFTs, they are freaking heavy, even empty. I’d have to look again to see their exact weights but it’s definitely more than regular external tanks
