| Radar is a sophisticated electronic machinery and equipment, from its date of birth, and his power lies in the continuous development of offensive weapons with a fierce air attack and defense. In today's modern war, radar was the "four threats" increasingly serious threat to these four is:integrated electronic interference, low-altitude or low altitude targets, anti-radiation missiles and stealth targets.Stealth targets due to their small cross-sectional area radar reflectivity, making difficult to find conventional radar, which can be flexible in the theater over the operations, achieved significant success. But comparatively speaking, as the meter wave radar, surveillance radar because of its wavelength appropriate, with the wave is absorbed is low, hard scattering characteristics of radar waves by absorbing and reducing the radar corner reflector, the scattering of radar waves to achieve the objectives of stealth purposes capture a certain effect, a stealth goal of a natural killer.However, as a result of low frequency VHF radar, the antenna structure is sparse, a large array area, a larger number of oscillators, the corresponding number of the transport unit will be more, disassembly, assembly, difficulties in transferring position, the general mobility is not high, and its erection, dismantling the heavy workload, often number 10 a few hours to complete. Therefore an urgent need of radar with high mobility and improve the viability of VHF Radar battlefield, when they need to quickly disassemble, assemble, quick transfer, quick set up and start work quickly to ensure uninterrupted monitoring air situation.Radar from the vertical hydraulic leveling system is an essential structure of the radar bearing organization and a major radar performance and quality assurance, radar mobility, reliability, security, To a great extent by the structural design and implementation. On the radar of modern warfare increasingly high demand for mobility, attention to the demolition of income and set up the radar speed. The program from home and abroad on the radar vertical hydraulic leveling system design techniques and methods, using a four leg swing plus automatic leveling jacks for the design and shorten the time of the radar set up to improve the leveling precision, improved Radar mobility. Proof of this design program of the superiority, and for other radar design and study lays a theoretical and technological basis. |
