Advanced Tactical Acquisition Radar (ATAR) 3D Active electronically scanned array (AESA) surveillance radar is the Command and Control Unit (CCU) for the SPYDER-SR. This radar can track and engage multiple targets simultaneously and can control the missile firing units at a distance of up to 10 km away from the CCU. The E/LM-2106 ATAR is a fourth generation defence radar designed by Elta and operates in the L-band wavelength. It is a field proven design that has operated in undesirable environments according to the designers and manufacturers. The range of detection for a fighter aircraft is 70–110 km. It can detect hovering helicopters at a range of 40 km and UAVs at 40–60 km. EL/M-2084 MMR The radar sensor unit of the SPYDER-MR comprises the EL/M-2084 Multi Mission Radar (MMR) 3D AESA radar. The EL/M-2084 operates in the S-band. It can process up to 1200 targets when in air surveillance mode and also detects targets located 250 km away. When the radar is static, it covers 120° in the azimuth. Surface-to-air missiles Ranges of Interception As a short range air defence system, the SPYDER-SR has a short range of interception. The maximum altitude of interception is 9 km and the maximum range of interception is 15 km. The SPYDER-MR has a greater operation range of 35 km and an altitude engagement of 16 km due to the missiles being equipped with boosters. Python-5 The Python-5 is currently the most capable air-to-air missile (AAM) in Israel's inventory and one of the most advanced AAMs in the world. As a beyond-visual-range missile, it is capable of "lock-on after launch" (LOAL), and has all-aspect/all-direction (including rearward) attack ability. The missile features an advanced electro-optical infrared homing (with imaging infrared) seeker which scans the target area for hostile aircraft, then locks-on for terminal chase. Derby The Derby is an active radar homing AAM that provides the SPYDER missile system with a fire-and-forget option due to its active radar guidance. In January 2023, Rafael announced that they had upgraded the Spyder to be able to counter tactical ballistic missiles by performing hardware and software upgrades to the Derby LR missile interceptor. Variants SPYDER-SR and SPYDER-ER 360° slant launching missile systems provide quick reaction, lock-on-before-launch (LOBL) and lock-on-after launch (LOAL) capabilities, while extending the range of defense to up to a 40 km radius. SPYDER-MR and SPYDER-LR offer medium & long range target interception through vertical
