Missile seeker

The open sight assembly allows the operator to aim the weapon, track the target, estimate range and apply tangent elevation. The sight carries an audible and vibratory indicator to show that the missile seeker has acquired the target... 

In contrast, the longer wavelength infrared (LWIR) band is desirable for imaging cooler bodies (such as the aircraft itself rather than just the hot engines, which can be masked ) and although LWIR detector materials and missile seekers have been...

THE MISSILE — propelled by a Teledyne turbojet engine - is 17.5 feet long, weighs 1100 j pounds, and carries a conventional warhead. It flies at wave height under midcourse inertial guidance until the radar seeker locks onto the target. The missile climbs for a brief instant near the target, then dives on it... 

Modern missiles employ counter-counter measures. Their advanced seeker heads use two or more spectral bands in an attempt to distinguish between the flare and the target. Trajectory discrimination may also be used by some seeker heads. The physical size of the heat source is more important as imaging seekers that can discriminate a spot target of IR flares, have been developed. Depending on their application, IR decoy flares can be further classified into ... 

This is the most advanced of the WAAM concepts and entails loading miniature missiles, each with its own new-technology seeker into cluster-bomb containers for low-level stand-off... 

The terms decoy flare or countermeasure munition are used to denote a system, which imitates the IR signal of a plane and therefore ground-air, water-air or air-air rockets, so-called heat-seeking missiles, get lured away from their targets. One of the first and best-known IR seekers - Sidewinder was developed in China Lake (Fig. 2.20). 

Your assignment Eliminate the heat-seeker base. It s easy enough to strafe the missiles on the ground, but if any are launched, you ll have to take evasive action. 

Use the joystick to control the movement of the plane. The controls may seem a little confusing at first. You pull back to loop upward (counterclockwise) and push forward to loop down (clockwise), like a real airplane. The jet moves at a constant velocity—you can t speed up or slow down. Press the fire button to launch a missile at the heat seekers on the ground. 

Seek Seeker—Refers to instrumentation for the guiding of missiles to the target. 

The SM-2 s speed is Mach 3.5, and its range is up to 170 kilometers. The missile has radar and an infrared seeker for terminal guidance, and it has a blast fragmentation warhead. The SM-2 is being replaced by the SM-6, which has twice the range and better radar and is more agile so that it can better deal with the Russian sizzler cruise missile. 

Usually there is a set of implementation related requirements that is given by the user, based on the platform on which the system is to be implemented. These may be size, weight, and power limits, as is the case with a missile-borne seeker or airborne intercepter system, or in the case of a remotely located land-based system, the requirements may not be size and weight related as much as reliability and maintainability related.

The use of IRCM flares is either pre-emptive or reactive. In the pre-emptive use, flares are deployed in a hostile environment in anticipation of a threat. Thus the release serves to reduce the contrast of the scene to impede lock-on and to make tracking of the actual target more diflicult. In the reactive mode, the actual target is already tracked by a seeker system and the flare aims to break the lock and to lure the missile away. In view of these necessities, the basic key requirements of decoy flares are the peak intensity, Jx(W sr ) and the rise time, dix/dt. A typical time/intensity specification for decoy flare defines rise time profile (d//dt), peak...
