DRDO Anti-Radiation Missile developmental trials. DRDO Anti-Radiation Missile The DRDO Anti-Radiation missile is a tactical, air-to-surface anti-radiation missile under development by India's Defence Research and Development Organisation. It is designed primarily to destroy enemy radars and communication facilities. This is a state-of-the-art air-to-surface anti-radiation missile being developed by Defence Research and Development Laboratory of the DRDO. The range of the missile is believed to be 100–125 km and it will be mounted on the combat aircraft of the IAF such as Sukhoi Su-30MKI and Tejas Light Combat Aircraft. The entire missile is being developed indigenously, including the seeker. According to the then Director
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
