The pod-mounted LIG NEX1 (formerly LG Innotek's Systems Division and then NEX1 Future) ALQ-200K E- through J-band radar jammer is designed for tactical aircraft applications (including the KF-16 and RF-4C types) and is targeted against anti-aircraft artillery, surface-to-air missile systems and airborne intercept emitters. It incorporates a transmitter chain, separate 'high-sensitivity' and channelised receivers, a system control unit, a 'jamming resource' package and a cockpit control interface unit. Of these, the ALQ-200K's transmitter chain includes fore and aft beam forming networks and multibeam, phased-array antenna assemblies and is described as offering a 'high' effective radiated power value. The equipment's system controller is reported as offering real-time processing, 'optimised' signal deinterleaving, jamming resource management, automatic built-in test, multi-channel tracking and 'multi-mission' scenario options. The jammer's receiver sub-system makes use of multi-baseline phase comparison direction-finding, while its 'jamming resource' package includes a digital radio frequency memory, a digitally-tuned oscillator, a continuous wave repeater and offers a range of noise, deception and 'complex' jamming modes. ALQ-200K is supported by a maintenance threat simulator and maintenance control analysis, automatic test unit and flight readiness programming stands. Other system features include a 'high-density' signal processing capability and the use of multiple central processing units and 'high-speed' signal processing to optimise jammer management.
