A Study on Passive and Active Detection of Missiles

Abstract

The Strategic missiles attempts to attack the enemy forces at a distance greater than ten thousand kilometers which are either propelled by the jet engines or the rockets. The detection and destruction of the missiles is a significant step for a nation to protect its land. Missile countermeasure methods are used to counter the missiles which includes active and passive methods. In Passive method the naturally emitted energy by the missile is detected whereas in the active detection method a radio signal is transmitted, and the backscattered signal is measured to find the range and the velocity of the target.
