of the K30 Biho Air Defense Unit of the
Republic of Korea Army A K30 Biho system consists of twin
KCB 30 mm guns, a TPS-830K surveillance and fire-control radar, an
electro-optical targeting system (EOTS), panoramic
periscope,
forward looking infrared system (FLIR),
laser rangefinder (LRF),
thermal sight, a TV camera, and a digital
fire-control system. The combined targeting system of EOTS, FLIR, and LRF has a targeting range of over . The TPS-830K radar can detect and track a -RCS target from a range of . In December 2013,
DAPA announced that the Biho had been integrated with the
Shingung surface-to-air missile to increase its coverage to 7 km. Two pods each containing two missiles are mounted, one of each side of the turret. Design integration with the missiles was completed in 2014, and by October 2015 the system was in full-rate production. The upgraded vehicle was in service by late 2018. The TPS-830K radar of K30 is an
X-band (8 to 12.5 GHz) surveillance and fire-control
pulse-Doppler radar, specialized for use against low-flying aircraft. Its features include real-time early warning, multiple target detection, an integral L-band (1 to 2 GHz)
Identification Friend or Foe (IFF) subsystem, pulse compression, frequency agility, and adaptive moving target indication as an anti-chaff measure. It supplies ballistic computation data to the digital fire-control system to direct the aim of the electro-optical targeting system, which then aligns the 30 mm guns with the target for accurate fire. The radar can be installed on a separate vehicle (usually a 5-ton six-wheeled truck with a self-towed generator unit) to serve as an independent surveillance platform for other short range air defense systems. The secondary FLIR system and laser rangefinder supplements the TPS-830K radar to provide additional targeting means in case the radar is rendered inoperative, or is turned off to retain the element of surprise against aircraft that are equipped with
radar warning receivers. The K30 adapts the chassis of the
K200 infantry fighting vehicle, but has some differences. It has an extra roadwheel in its suspension and uses a D2840L engine instead of the D2848T engine of the K200, with an increase in engine power from 350 horsepower to 520 horsepower, necessary since the K30 weighs almost twice as much as the K200.
Allison Transmission's X200-5K transmission is likewise replaced by
S&T Dynamics' HMPT500-3EK/4EK to accommodate the more powerful engine. The modified chassis largely retains the protection and amphibious capability of the original chassis. ==Variants==
