ИМХО, замерять его сигнатуру в ИК-спектре куда больше смысла имеет.
У Хищника-22 ИК сигнатура в задней полусфере довольно интересная должна быть. Есть у меня одно фото в ссылках на работе.
Есть интересное про F-35. Состав БРЭО и конструкция частично будут понятны вам.
DESIGN
In order to minimise the structural weight and complexity of assembly, the wingbox section integrates the wing and fuselage section into one piece. To minimise radar signature, sweep angles are identical for the leading and trailing edges of the wing and tail (planform alignment). The fuselage and canopy have sloping sides. The seam of the canopy and the weapon bay doors are sawtoothed and the vertical tails are canted at an angle.
The Marine variant of JSF is very similar to the Air Force variant, but with a slightly shorter range because some of the space used for fuel is used for the lift fan of the STOVL propulsion system. The main differences between the naval variant and the other versions of JSF are associated with the carrier operations. The internal structure of the naval version is very strong to withstand the high loading of catapult assisted launches and tailhook arrested landings. The aircraft has larger wing and tail control surfaces for low speed approaches for carrier landing. Larger leading edge flaps and foldable wingtip sections provide a larger wing area, which provides an increased range and payload capacity.
The canopy, radar and most of the avionics are common to the three variants.
WEAPONS
Weapons are carried in two parallel bays located in front of the landing gear. Each weapons bay is fitted with two hardpoints for carrying a range of bombs and missiles. Weapons to be cleared for internal carriage include: JDAM (Joint Direct Attack Munition), CBU-105 WCMD (Wind-Corrected Munitions Dispenser) for the Sensor-Fuzed Weapon, JSOW (Joint StandOff Weapon), Paveway II guided bombs, AIM-120C AMRAAM air-to-air missile; for external carriage: JASSM (Joint Air-to-Surface Standoff Missile), AIM-9X Sidewinder and Storm Shadow cruise missile.
In September 2002, General Dynamics Armament and Technical Products was selected as the gun system integrator. The air force variant has an internally mounted gun. The Carrier and Marine variants can have an external gun pod fitted.
TARGETING
Lockheed Martin Missile & Fire Control and Northrop Grumman Electronic Sensors and Systems are jointly responsible for the JSF electro-optical system. A Lockheed Martin electro-optical targeting system (EOTS)
will provide long-range detection and precision targeting, along with the Northrop Grumman DAS (
Distributed Aperture System)
thermal imaging system.
EOTS will be based on the Sniper XL pod developed for the F-16, which incorporates
a mid-wave third generation FLIR, dual mode laser, CCD TV, laser tracker and laser marker. BAE Systems Avionics in Edinburgh, Scotland will provide the laser systems.
DAS consists of multiple infrared cameras (supplied by Indigo Systems of Goleta, California)
providing 360º coverage using advanced signal conditioning algorithms. As well as situational awareness, DAS provides navigation, missile warning and infrared search and track (IRST). EOTS is embedded under the aircraft’s nose, and DAS sensors are fitted at multiple locations on the aircraft.
RADAR
Northrop Grumman Electronic Systems is developing the advanced electronically scanned array (AESA) AN/APG-81 multi-function radar.
The AN/APG-81AESA will combine an integrated radio frequency subsystem with a multifunction array. The radar system will also incorporate the agile beam steering capabilities developed for the APG-77.
COUNTERMEASURES
BAE Systems North America will be responsible for the JSF integrated electronic warfare suite, which will be installed internally and have some subsystems from Northrop Grumman. BAE is developing a new digital radar warning receiver for the F-35.
AVIONICS SYSTEMS
The following will supply the F-35 avionics systems: BAE Systems Avionics - side stick and throttle controls; Vision Systems International (a partnership between Kaiser Electronics and Elbit of Israel) - advanced helmet-mounted display; Ball Aerospace - Communications, Navigation and Integration (CNI)
integrated body antenna suite (
one S-band, two UHF, two radar altimeter, three L-band antennas per aircraft); Harris Corporation - advanced avionics systems, infrastructure, image processing, digital map software, fibre optics, high speed communications links and part of the Communications, Navigation and Information (CNI) System; Honeywell - radar altimeter, inertial navigation/global positioning system (INS/GPS) and air data transducers; Raytheon - 24-channel GPS (Global Positioning System)
with digital anti-jam receiver (DAR).
SYSTEMS
Other suppliers will include:
ATK Composites - upper wing skins;
Vought Aircraft Industries - lower wing skins; Smiths Aerospace - electronic control systems and electrical power system (with Hamilton Sundstrand), integrated canopy frame; Honeywell - landing system's wheels and brakes, onboard oxygen-generating system (OBOGS), engine components, power and thermal management system driven by integrated auxiliary power unit (APU); Parker Aerospace - fuel system, hydraulics for lift fan, primary flight control electrohydrostatic actuators (with Moog Inc), engine controls and accessories; EDO Corporation - pneumatic weapon delivery system; Goodrich - lift-fan anti-icing system; Stork Aerospace - electrical wiring.
