LR66 Radar
Type LR66 radar is a Chinese fire control radar or Type 349 for Type 730 CIWS developed bthe 20th Research Institute of China Electronics Technology Group Corporation (CETGC, 中国电子科技集团公司第二十研究所) also known as Xi’an Research Institute of Navigation Technology (西安导航技术研究所). Developed as one of the latest member of Type 347 Radar, Type 347/Type 348 Radar, Type 348/Type 349 Radar, Type 349/LR66 series, LR66 radar is designed to control both CIWS of smaller caliber and the main gun of larger caliber. The system is very compact, needing only two cabinets, and a single operator console. LR66 fire control radar is connected to search radar via Ethernet. Specification: *Band: X or J band *Probability of kill: 90% *Range (km) against target with radar cross section of 2 square meters: > 18 *Range (km) against target with radar cross section of 0.1 square meters: > 9 *Maximum effective altitude (km): 15 *Frequency agile band (GHz): > 2 *Azimuth a ...

Type 730 CIWS
The Type 730 is a Chinese seven-barrelled 30 mm Gatling gun/Rotary cannon CIWS. It has a PLA Navy designation H/PJ12. It is mounted in an enclosed automatic turret and directed by radar, and electro-optical tracking systems. The maximum rate of fire is 5800 rd/m, and the effective range is up to 3 km. Development The gun is designed by the 713th research institute under the name 'Project 850' and is powered by two electric motors. The radar TR47C is a derivative of the EFR-1/LR66 J-band radar (NATO code name: Rice Lamp) by Xi'an Research Institute of Navigation Technology, but it is unclear that if this derivative is developed by the same institution. The OFC (Optical Fire Control)-3/H/ZGJ-4 electro-optical fire control system is designed by the Central China Optronic (electro-optical) Research Institute. Origin The system's primary purpose is defense against anti-ship missiles, and other precision guided weapons. However, it can also be employed against fixed/rot ...

Type 347 Radar
The Type 347G "Rice Bowl" I-band fire-control radar is found on Chinese Navy ships, in conjunction with the Type 76A dual-37mm automatic AAA gun. Typically, the system includes 2 Type 347G fire-control radar with optical director, and 4 Type 76A guns. They're used on the Luda, Luhu, Luhai, Jiangwei class surface warships, as well as the Houjian, Houxin, and Haiging class patrol boats. Development Development for an air defense radar system begun in July 1974, with design finalized in August 1975, consisted of two radars, the 1st being a search radar designated as Type 347S with S stands for search, and a 2nd fire control radar for guns, designated as Type 347G with G as gun. Design was completed by the 723rd Institute in May 1976 and finalized in October 1977. In the 1980s, China imported the OTOBreda (now OTO-Melara) Twin Fast Forty AAand Selenia (now AMS) SPG-74 (RTN-20X) fire control system from Italy for evaluation. Although the Chinese navy didn't deploy the twin-40mm AAA, t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Type 348 Radar
Type 348 radar is a Chinese fire control radar developed for Type 76 twin 37 mm naval gun as CIWS, and it incorporates features of Italian RTN-10X and RTN-20X sold to China in 1992. Type 348 radar is frequently but erroneously confused and misidentified as another Chinese naval radar Type 346 due to the lack of publicized information in the development of the latter. Development To meet the urgent Chinese naval need of CIWS before the availability of more advanced CIWS such as Type 730 CIWS, Type 348 radar is developed as a stopgap measure by developing a less capable CIWS using Type 76 twin 37 mm guns. The muzzle velocity of twin 37 mm is 1 km per second, and the maximum rate is 800 round per minute, with a range of 3 km. However, early developmental trials have revealed that the original fire control radar Type 342 used proved to be rather inadequate in tracking sea-skimming anti-ship missiles, consequently, Type 348 radar was developed as a replacement, in ...

Naval Weaponry Of The People's Liberation Army Navy
The People's Liberation Army Navy (PLAN) is the naval branch of the People's Liberation Army (PLA), the armed forces of the People's Republic of China. The PLAN force consists of approximately 250,000 men and over a hundred major combat vessels, organized into three fleets: the North Sea Fleet, the East Sea Fleet, and the South Sea Fleet. Most of the naval weapon systems used by the PLAN were developed prior to 1990. The naval weaponry of the PLAN is based on three tiers: artillery, torpedoes, and missiles, each geared to a specific threat range and type. History Throughout its early history from 1949 to the early 1980s, the PLAN had principally relied upon artillery and torpedoes as its main weapons. This resulted in the development of many types and calibers of anti-aircraft and anti-ship guns. Torpedoes were secondary weapons, playing an important role in PLAN's coastal defense doctrines. Many destroyers, frigates and torpedo craft all carry an array of anti-ship torpedoes to th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sea Radars
The sea, connected as the world ocean or simply the ocean, is the body of salty water that covers approximately 71% of the Earth's surface. The word sea is also used to denote second-order sections of the sea, such as the Mediterranean Sea, as well as certain large, entirely landlocked, saltwater lakes, such as the Caspian Sea. The sea moderates Earth's climate and has important roles in the water, carbon, and nitrogen cycles. Humans harnessing and studying the sea have been recorded since ancient times, and evidenced well into prehistory, while its modern scientific study is called oceanography. The most abundant solid dissolved in seawater is sodium chloride. The water also contains salts of magnesium, calcium, potassium, and mercury, amongst many other elements, some in minute concentrations. Salinity varies widely, being lower near the surface and the mouths of large rivers and higher in the depths of the ocean; however, the relative proportions of dissolved salts vary li ...
