5 月 12 日 to 14, the Seventh China International Defense Electronics Exhibition held in Beijing, at China’s first public display of “high-frequency ground wave radar “of great concern. This accurate detection range of up to 300 km above the car radar, can be deployed on the coast, our country’s exclusive economic zone detection, and detection of ships, aircraft and missiles moving target. Foreign media that the advent of ground wave radar, means that China’s “anti-aircraft missiles” into a real combat deployment phase.

March this year, China’s “Liberation Army Daily,” the disclosure of the East China Sea Fleet, the radar unit fitted out a new situation, the report refers to “enemy carrier aircraft had just left the deck, he was captured new radar,” which caused speculation about the outside world. Retired Admiral Lanning Li Taiwan in March this year was the “Asia-Pacific Defense” magazine, the author believes that the mainland has been equipped with a can-the-horizon detection of ground wave radar.

United States, “Defense News,” said China confirmed on display outside the ground wave of speculation. But China did not emphasize which exhibitors radar for military purposes. According to reports, this number OSMAR-071/081 series of high-frequency surface wave radar is the only armed forces in accordance with military standards and was developed using the ground wave radar products, currently has a portable, automotive, stationary and other island-specific products. Because China has a vast area of ??the jurisdiction of the sea, these waters to the effective management and control, there must be a corresponding large-scale, long-range detection means, to make up our radar early warning aircraft and coastal defense radar deficiencies. OSMAR-071 radar was the end of 2009 in the South China Sea Jianzhan.

According to experts, ground radar and the two main days of radar detection of the sea means, they transmit high-frequency radio waves through the work. Days of radar works by the ionosphere to the atmosphere in high-frequency radio signal transmitter, when the waves reach the ionosphere, will be reflected back to the ground. Days of radar detection range of more than 3,000 kilometers, a distance detection. However, the days of radar need to build a few hundred meters of the radar antenna to detect ionospheric effects are susceptible to interference. USA 1961 developed the days of radar, in addition to the local deployment, the deployment is currently underway in Japan.

ground wave principle is different. As the sea is a good conductor of radio waves, radio waves transmitted from ground radar along the sea “crawl”, so you can break the horizon, to detect targets 300 kilometers away. Although the detection range is shorter, but the small size of surface wave radar, detection accuracy is also higher. United States and Russia since the 1960s, began research and development, ahead of China.

because the sea can be accurately detected over the horizon, outside the radar of the speculation focused on “anti-aircraft warfare” on. Lanning Li believes that the mainland as early as 1967 began the development of surface wave radar system. Ground wave radar deployment, that “anti-aircraft missiles” into the actual deployment phase. Lanning Li stressed that the PLA anti-ship ballistic missile is a complex integrated system, to form a complete “chain of destruction.” Continental defense industry has taken to further increase the scope of the regional fight against anti-ship ballistic missiles, the current work is to ensure that the various intelligence and reconnaissance and command and control system to ensure anti-ship missile hit the 1500-2000 km range of the aircraft carrier battle group.
