DRDO Anti-Radiation Missile G. Satheesh Reddy, the missile will feature a millimeter wave seeker capable of lock-on before launch and lock-on after launch modes. The missile picks up the radiation or signals of radars and communication facilities and homes on to the targets to destroy them. Instead of thrust propulsion, the missile uses dual pulse propulsion system just like Barak-8/LR-SAM. The benefit of dual pulse propulsion is that it will widen the envelope as well as the engagement capability of the missile. Work on the project began in 2012 at one of the DRDO laboratories soon after the project was given the go-ahead
Refraction Refraction In physics refraction is the change in direction of a wave passing from one medium to another or from a gradual change in the medium. Refraction of light is the most commonly observed phenomenon, but other waves such as sound waves and water waves also experience refraction. How much a wave is refracted is determined by the change in wave speed and the initial direction of wave propagation relative to the direction of change in speed. For light, refraction follows Snell's law, which states that, for a given pair of media, the ratio of the sines of the angle
