  Heat-Seeking Missile Guidance
The initial deployment of heat seeking missiles began in the late 1950's, with the USAF acquiring it's first AIM-4 Falcons and AIM-9 Sidewinders, however, it was not until the Viet-Nam war that the AIM-9 saw widespread use.
The principal heat source is the propulsion, as jet engines have an efficiency far below 100%, a considerable amount of energy is thrown away, advertising the aircraft's position.
Heat seeking missile guidance is, after more than twenty five years of use, anything but obsolete.

 PhysOrgForum Science, Physics and Technology Discussion Forums -> My Fridge Died!
Heat is also defined as the energy transferred between two systems that have a temperature difference.
So heat wouldn't travel in a vacuum unless the two objects were in contact, but you could heat something up in a vacuum with something like microwaves.
Heat mainly is said to be the average kinetic energy of gas molecules (when referring to a gas), more solid substances and this becomes vibration rather than velocity.

 Heat seeking closure, with or without Wade | The San Diego Union-Tribune
MIAMI – If the Miami Heat's chances in Game 6 of the NBA Eastern Conference finals hinged on the health of a short, middle-aged, mustachioed man, then it would be in excellent shape.
These days, Heat coach Stan Van Gundy is about the only member of the team not nursing some ailment or injury.
If he can't go, the Heat would be without a player who has averaged 27 points per game through the first five games of the series, best on the team.

 Sperm Act Like Heat-Seeking Missiles When Searching For Egg, Could Aid Infertility Treatments
New research suggests that sperm are at least partially guided on their fertilization mission by heat given off by the egg's nest.
The place where the egg lies is slightly warmer than the place where mature sperm begin the final leg of their journey through the female reproductive system, according to the researchers of a new study in the February issue of Nature Medicine.
The researchers say it seems to be a combination of chemistry and heat between the two players.

Obviously the wheels don't get their power from the heat, but with each wheel turning more or less in response to the heat it feels, the whole comfy rug should always naturally gravitate towards the most cosy toasty warm spot in the room.
I was originally going to use thousands of tiny suction-cups on the underside of the rug, and have it crawl towards the heat using tiny, millipede-leg type waves, but that was a bit too tricky to work out.

With regards to the Sa18 Heat Seeking missile which is an updated version of SA 7 which uses passive infra red (particularly in the long wave invisible spectrum), provides a very simple and inexpensive process to eliminate these incoming heat seeking missiles.
By altering a microwave transmission to a half wave form at a potential comparable to the DC driven primary input of typically 200,000 Volts at a carrier current of 5,000 ma of energy.

The Bird of Prey's engine intake is situated behind the cockpit, hiding its thermal signature from ground-launched missiles or thermal-imaging devices.
To avoid detection by thermal imaging devices or targeting by heat-seeking missiles, stealthy aircraft must minimize heat emissions.
Another source of heat is air friction caused by travel at very fast speeds, an effect that is particularly pronounced at the wing's leading edge.

Pearce devises mathematical models that can predict both the level of heat or energy emitted by the prey and the impact this would have at a given distance from the snake's powerful receptors.
Pearce is a co-principal investigator in a $5 million project funded by the U.S. Air Force to study remote sensing abilities found in several types of beetles and snakes.

Infrared systems of that era were infamous for their inability to discriminate between heat emitters; they simply went after whatever presented the biggest and hottest target.
Additionally, the antenna tuning units -- assumed to be correctly tuned -- would not have generated or emitted a high degree of heat.
Perhaps there were impedance matching autotuners in the base of the damaged antenna systems (which appear to be HF, broadband, vertical grounded sleeve antennas in the pictures).

 Infrared homing - Wikipedia, the free encyclopedia
Missiles which use infra-red seeking are often referred to as "heat-seekers".
Many objects such as people, vehicle engines and aircraft generate and retain heat, and as such, are especially visible in the infra-red wavelengths of light compared to objects in the background.
Background heat from inside the sensor, or the aerodynamically heated sensor window, can overpower the weak signal entering the sensor from the target.

The system, developed by Invisible Heating Systems (IHS), the firm that he set up with Liz Stewart, is used in more than 200,000sq m of motorway in the Netherlands to heat industrial units, while an airport runway heats 2,500 nearby homes.
Excess heat absorbed during the summer can be pumped into heating systems and roads during winter.
In winter, the water can drop to about 15C, still warm enough to keep roads frost-free and to heat industrial buildings, but a heat pump is then used to bring the temperature up to over 35C for use in offices or houses.

Their mountain sanctuaries in Mexico like, for example, at El Rosario in Michoacán, are filled with Oyamel fir trees, which are used for resting between flights and for shelter from the cold, rain and snow (they seek out an environment similar to the one they inhabit up north).
The butterflies like temperatures of around 23°C, so when a cold wind or cloud appears, they head for the nearest Oyamel to huddle together in stacks like pancakes, literally bending the tree branches with their weight.
They'll even seek out the body heat of a human being-if you stand still for a few minutes, they'll flutter over and shamelessly perch on your head or shoulder.

Although classed as "fire and forget" types, the missiles were easily overcome by solar heat and, when used in hilly terrain, by heat from the ground.
The SA-7 seeker is fitted with a filter to reduce the effectiveness of decoying flares and to block IR emissions.
Both the SA-7a and SA-7b are tail-chase missile systems, and its effectiveness depends on its ability to lock onto the heat source of low-flying fixed- and rotary-wing aircraft targets.
