Thread: Missile interseption systems

How missile interception systems usually work? Do they use radars to detect missiles?
Israel recently reported success in interception of some missiles.
I wonder, is it so difficult under modern technologies to make a missile completely from dielectric materials?
Such as ceramics, fiberglass?

Yes, radar.

Why would you want to do so?
You can't make the entirety out of, say, fibreglass, it has to be strong enough to withstand launch/ manoeuvre accelerations, internal pressure/ temperature (of the propellant perhaps) external temperature/ pressure (air at Mach Whatever), plus the mechanical parts: pumps, gyros and the like.

Are dialectics less susceptible to detection by radar?

Could use Buckypaper one day.

Among the possible uses for buckypaper that are being researched:

• Fire protection: covering material with a thin layer of buckypaper significantly improves its fire resistance due to the efficient reflection of heat by the dense, compact layer of carbon nanotubes or carbon fibers.^[9]
• If exposed to an electric charge, buckypaper could be used to illuminate computer and television screens. It could be more energy-efficient, lighter, and could allow for a more uniform level of brightness than current cathode ray tube (CRT) and liquid crystal display (LCD) technology.
• Since individual carbon nanotubes are one of the most thermally conductive materials known, buckypaper lends itself to the development of heat sinks that would allow computers and other electronic equipment to disperse heat more efficiently than is currently possible. This, in turn, could lead to even greater advances in electronic miniaturization.
• Films also could protect electronic circuits and devices within airplanes from electromagnetic interference, which can damage equipment and alter settings. Similarly, such films could allow military aircraft to shield their electromagnetic "signatures", which can be detected via radar.
• Buckypaper could act as a filter membrane to trap microparticles in air or fluid. Because the nanotubes in buckypaper are insoluble and can be functionalized with a variety of functional groups, they can selectively remove compounds or can act as a sensor.
• Produced in high enough quantities and at an economically viable price, buckypaper composites could serve as an effective armor plating.
• Buckypaper can be used to grow biological tissue, such as nerve cells. Buckypaper can be electrified or functionalized to encourage growth of specific types of cells.
• The Poisson's ratio for carbon nanotube buckypaper can be controlled and has exhibited auxetic behavior, capable of use as artificial muscles.

Two different questions. I won't address the ideas of escaping radar detection here.

Isreal and like the American Patriot systems do use radar. This needs to be very precise. The radar needs
to measure the speed and distance and position of the missile. It also needs precise acceleration algorithms in place to determine the timing and speed and acceleration of a launch of an interception missile. The split-second timing
has to be very precise.
