''' Mehrab (Rocket) ''' An intermediate-range surface-to-air smart-missile that sends signals to a location for target tracking. The missile can target different goals in land, sea, and air; with the first ninety missiles tested and unveiled. The Mehrab missile, a medium-range missile with a surface-to-air missile system, is fundamentally different.
The most important feature of the missile is that the mihrab can also deal with enemy electronic warfare. In fact, the missile uses an altered version of "Zdsamanhay radar" system, to target an enemy trying to start a war: the Electronic Akhlagr is to send signals that distract missiles and the Mehrab will abandon its primary target and track the source of the disruptive signal, redirecting itself toward the new target. In the absence of disruptive signals, the rocket altars its course using radar waves reflected from the target that belong to the forces sent and received by the missile. It seeks the reflected waves; aiming to hit their source.
The missile uses solid fuel to move towards the goals. In the latest example, Iranian frigate Damavand or Jamaran, two days serving, as it operationally tested its systems and equipment in the waters of the Caspian Sea, is now equipped with an advanced missile system and soon will have the army officially join the fleet and Navy. Earlier, a missile-equipped naval destroyer was found in the waters south of the country and Navy. Perhaps the main reason for equipping the two frigates with this missile defense are high power and high speed through utilizing advanced Radrhay. The giant ships are primarily known for low speed and massiveness. High defenses must therefore also use the system and missile defensive redirector installed on the two carriers. Ships using this system are protected against cruise missiles, aircraft, and surface invading enemies in a battle.
