surveillance radar

A radar primarily meant to scan 360° in azimuth and provide information on the range and the azimuth of the aircraft in its range. Information on the target’s height may or may not be available. However, modern surveillance radars do provide both azimuth and elevation data, and in conjunction with secondary surveillance radar (SSR), it is possible to establish identity and provide separation, navigational assistance, storm warning, and even vectoring of the aircraft onto the final approach. Surveillance radars are divided into two general categories: airport surveillance radar (ASR) and air route surveillance radar (ARSR). Long-range air defense surveillance radars are akin to air route surveillance radars.
