The EL/M-2248 MF-STAR is a multifunction active electronically scanned array naval radar system developed by IAI Elta for maritime installation on warships. It is capable of tracking both air and surface targets and providing fire control guidance. MF-STAR is an acronym of Multi-Function Surveillance, Track And Guidance Radar.

Active electronically scanned array
An active electronically scanned array (AESA) is a type of phased array antenna, which is a computer-controlled antenna array in which the beam of radio waves can be electronically steered to point in different directions without moving the antenna. In the AESA, each antenna element is connected to a small solid-state transmit/receive module (TRM) under the control of a computer, which performs the functions of a transmitter and/or receiver for the antenna. This contrasts with a passive electronically scanned array (PESA), in which all the antenna elements are connected to a single transmitter and/or receiver through phase shifters under the control of the computer. AESA's main use is in radar, and these are known as active phased array radar (APAR).
