The Fan Song is the NATO reporting name for SNR-75 series of trailer-mounted E band/F band and G band fire control and tracking radars for use with the Soviet SA-2 Guideline surface-to-air missile system.



The Fan Song radars are capable of tracking a single target at a time, and can guide up to three missiles at once to it. The radars feature two orthogonal antennas, one for azimuth and one for elevation, which can operate in a track-while-scan mode. These antennas transmit 10 × 2 degree or 7.5 x 1.5 degree beams and perform a 'flapping' motion as they scan their sectors. [1] [2]

The Fan Song E includes two additional parabolic dishes for narrow beam and LORO tracking modes. [3]

Phased array

In antenna theory, a phased array usually means an electronically scanned array, a computer-controlled array of antennas which creates a beam of radio waves that can be electronically steered to point in different directions without moving the antennas.

Active electronically scanned array Type of phased array radar

An active electronically scanned array (AESA) is a type of phased array antenna, which is a computer-controlled array antenna 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).

Beam-riding, also known as Line-Of-Sight Beam Riding (LOSBR) or beam guidance, is a technique of directing a missile to its target by means of radar or a laser beam. The name refers to the way the missile flies down the guidance beam, which is aimed at the target. It is one of the simplest guidance systems and was widely used on early missile systems, however it had a number of disadvantages and is now found typically only in short-range roles.

Tor missile system Tracked SAM system

The Tor missile system is an all-weather low to medium altitude, short-range surface-to-air missile system designed for destroying airplanes, helicopters, cruise missiles, precision guided munitions, unmanned aerial vehicles and short-range ballistic threats (anti-munitions). Originally developed by the Soviet Union under the GRAU designation 9K330 Tor, the system is commonly known by its NATO reporting name, SA-15 "Gauntlet". A navalized variant was developed under the name 3K95 "Kinzhal", also known as the SA-N-9 "Gauntlet". Tor was also the first air defence system in the world designed from the start to shoot down precision guided weapons like the AGM-86 ALCM day and night, in bad weather and jamming situations. Tor can detect targets while on the move. The vehicle must stop intermittently when firing, although trials are being conducted to eliminate this restriction.

Fire-control radar

A fire-control radar (FCR) is a radar that is designed specifically to provide information to a fire-control system in order to direct weapons such that they hit a target. They are sometimes known as targeting radars, or in the UK, gun-laying radars. If the radar is used to guide a missile, it is often known as an target illuminator or illuminator radar.

Counter-battery radar

A counter-battery radar is a radar system that detects artillery projectiles fired by one or more guns, howitzers, mortars or rocket launchers and, from their trajectories, locates the position on the ground of the weapon that fired it. Such radars are a subclass of the wider class of target acquisition radars.

Rajendra Radar Fire-control radar

Rajendra is a passive electronically scanned array radar developed by the Defence Research and Development Organisation (DRDO). It is a multifunction radar, capable of surveillance, tracking and engaging low radar cross section targets. It is a ground surveillance radar and is a great source of surveillance operating at frequency around 20 GHz. It is mainly used to track enemy's installations.

AN/MPQ-64 Sentinel

The AN/MPQ-64 Sentinel is a 3D radar used to alert and cue Short Range Air Defense (SHORAD) weapons to the locations of hostile targets approaching their front line forces. The Sentinel radar is deployed with forward area air defense units of the U.S. Army. It is an X-band range-gated, pulse-Doppler radar system. The antenna uses phase-frequency electronic scanning technology, forming sharp 3D pencil beams covering large surveillance and track volume. The radar automatically acquires, tracks, classifies, identifies and reports targets, including cruise missiles, unmanned aerial vehicles, and both rotary- and fixed-wing aircraft. It uses a high scan rate and operates at a range of 40 km (25 mi). The radar is designed with high resistance to electronic countermeasures (ECM). Mounted on a towed platform, it can be positioned remotely from the rest of the unit, operated autonomously and communicate with the Fire Direction Center (FDC) via wideband fiber-optic link. It can also distribute its data over a SINCGARS radio network.

S-75 Dvina Strategic SAM system

The S-75 is a Soviet-designed, high-altitude air defence system, built around a surface-to-air missile with command guidance. Following its first deployment in 1957 it became one of the most widely deployed air defence systems in history. It scored the first destruction of an enemy aircraft by a surface-to-air missile, with the shooting down of a Taiwanese Martin RB-57D Canberra over China on 7 October 1959 that was hit by a salvo of three V-750 (1D) missiles at an altitude of 20 km (65,600 ft). This success was credited to Chinese fighter aircraft at the time to keep the S-75 program secret.

Monopulse radar is a radar system that uses additional encoding of the radio signal to provide accurate directional information. The name refers to its ability to extract range and direction from a single signal pulse.

Giraffe radar

The Saab Giraffe Radar is a family of land and naval two- or three-dimensional G/H-band passive electronically scanned array radar-based surveillance and air defense command and control systems tailored for operations with medium- and Short Range Air Defense (SHORAD) missile or gun systems or for use as gap-fillers in a larger air defense system. The radar gets its name from the distinctive folding mast which when deployed allows the radar to see over nearby terrain features such as trees, extending its effective range against low-level air targets. The first systems were produced in 1977. By 2007, some 450 units of all types are reported as having been delivered.
