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
Seismic refraction velocity of the first layer V - velocity of the second layer h - thickness of the first layer T0 - intercept Seismic refraction Seismic refraction is a geophysical principle (see refraction) governed by Snell's Law. Used in the fields of engineering geology, geotechnical engineering and exploration geophysics, seismic refraction traverses (seismic lines) are performed using a seismograph(s) and/or geophone(s), in an array and an energy source. The seismic refraction method utilizes the refraction of seismic waves on geologic layers and rock/soil units in order to characterize the subsurface geologic conditions and geologic structure. The methods depend on the fact
