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
A/B Sound System A/B Sound System An A/B Sound System is a type of Sound reinforcement system or Public address system. Unlike a more typical sound reinforcement system, an A/B Sound System provides two electrically isolated signal paths from microphone to speaker, resulting in a system where signals from two microphones only interact acoustically and never interact electronically. This is accomplished by placing two separate loudspeakers at each speaker position and feeding the two speakers separate signals from separate microphones. The purported benefit of such a system is a reduction in phase cancellation and intermodulation distortion, and an improvement in speech intelligibility when
