Without any pulsing in radar operation is a continues waves radar (CW
radar) by through a pulse signal as frequency. It determined the radial
component of a target range of velocity. And other calibration used to
determine the radar signal that methods also followed by time-frequency
analysis.
Super & Hyper sonic missile systems:
Super and hypersonic is a group of cruise guided missile systems
[19]. It is used against the accurate terrestrial target and major
portions of its air path assigned speed. Its arrival long distance and
high accuracy delivered the warheads. And modern cruise missile is the
efficiency of capable to travelled in supersonic and hypersonic speed
and self diversion guided the GPS or radar signals. To destroy the
enemies shelters and building. Its has different in many types depending
on warheads.
Types cruise missile:
Short-range missile (140 to 900Km)
Medium range missile (1000Km)
Long-range missile (5500Km)
Intercontinental range missile (8500 to 10200 or more)
A general cruise missile is consists of guidance in GPS or radar systems
[20]. Its explosive loads to carry the high speed the airframe to
travelled to the controlled the empennage. Explosive payloads are 2
types of conventional explosive and nuclear warheads. Missile propulsion
systems are different from the depend on the launching station the
ground to ground, ground to air, air to land target cruise missiles
propulsion systems are based on the solid fuels and turbo engines. The
turbo engine preferred due to their great efficiency at altitude and
subsonic speed. Guidance systems also fluctuate greatly low-cost systems
use a radar altimeter, digital strip map. Super and hypersonic missile
systems are used advance method are internal guidance satellite guidance
controlled the ground stations points. And visible of ground terrain
counter matching (TERCOM) [21]. Missile launching to the station to
pre-programming forms recognized the Automatic Target Recognition (ATR)
[22]. Algorithm calibration devises guidance systems it guides the
ground to satellite and satellite to missile command are passing to
diversion assigned destructive in precious targets [23]. Altercation

Industrial Bunkers
Characteristic industrial bunkers are used in food storage, data
storages are explosive storages in a WW 2 periods [24]. It some
protective industrial test in the scientific contribution of new
inventions there are missile warheads, rocket motor engines or explosive
experiments. And its operation of control rooms is one of the part of
the job in industrial bunkers. It is stored in radioactive explosive
ammunition and sometimes its build in an atomic or hydrogen bombs
[25]. Types of bunkers are build in an underground referred depth
and provided metallic doors in secret inspections. Majorly worn in this
bunkers in protected the important of aerial bombardment and specific
conditions of bombs. Such type of industrial bunkers also exists on
non-military conveniences.
Special Bunkers:
That bunker is specially constructed with personal or domestic nuclear
bunkers as shown in figure 7. Are built in house with normal locations
[26]. It is available beneath the plinth level of the house that
spaces of subfloors into the residential house. Its mostly used for
purposes of old valuable thing food preparation materials, paper stacks,
important files and radio signal & weapons are stored. Are the
availability of large cabinets with bathroom. The shelter is beneath the
residential buildings or separated to constructed the underground
surfaces near the residency. The shelter is fully based on
fibre-reinforced plastic shells [27]. Volumetric compression safety
is are provided at inexpensive or irregular earth pressure and safely
protection of nuclear radiation. It is for eternity purposes of safety
rooms in wartime periods.
