At the moment, national radar is at least serving in the east, north and west of the country and is used as part of the air surveillance chain at long distances and early warning. National radar limitations, especially in terms of production constraints, are lower than existing radars. The other advantage of the national radar is to automate many of its functions so that it can easily connect to a fully integrated and integrated national air defense system.
Another advantage of this is the operational comfort of the team, because the radar has obviously clear signs (scopes), and the user easily finds the goals from the fixed goals easily. The most important advantage of the national radar is that it is easy for the technical team and the repair process because the radar is quickly diagnosed and eliminated due to the use of new technologies. In fact, due to the built-in radar's long range, it's possible to cover a wide part of the country that was not previously possible. The results of the research by the experienced radar staff on the world-level technologies made the national radar with high-range conditions and a very good distance and angle separation, and most importantly, cut off the dependence of the world. This radar was built alongside the 1 and 2 digital receivers that were added to the existing radar systems at that time. The first radar designed and developed native radar is National. Prior to this, the great work of transmitters, receivers and some of the components of the radar systems was repaired by the specialists, and in the absence of the necessary parts of the sanctions, by designing that section natively, the piece or section (module) of Iran was installed on the system. This eventually led to the construction of a national radar with a range of 450 kilometers in 1998, the stages of its design and construction were entirely carried out by the internal forces. The arrival of new radars to Iran after the imposed war and its functional differences with the existing experts of the country made this decision that digital radar and internal construction should be provided. Search radars may support various air defense systems, while engagement radars are normally associated with a specific type of surface to air missile. Search radars use lower frequency transmissions to determine the general location of a target, while engagement radars operate at higher frequencies to achieve greater precision in target location. A tracking radar is normally directed by a scanning radar, so the tracking radar can limit its search for a target to a very small range, azimuth and elevation sector at a time.
Search radars typically have ranges of several hundred kilometers, while engagement radars operate at ranges of tens of kilometers. The air defense mission is 1) to detect, track and identify all air vehicles entering the assigned air space, 2) to intercept unidentified objects, and 3) to shoot down or turn back hostiles (also called penetrators or intruders) soon after they enter defense sensor coverage. Air defense radars include scanning (search) radars and tracking or engagement (fire control) radars.
