Folding device for onboard high-mobility large antenna array radar

Abstract

The invention discloses a folding device for an onboard high-mobility large antenna array radar. The folding device comprises an antenna base. A support protection device is arranged on the left end of the antenna base. A lower array antenna frame is installed on the top of the antenna base through a hinge seat. The left side of the top of the lower array antenna frame is connected to the antennabase by an overturning pitch mechanism. The top of the lower array antenna frame is connected with an upper array antenna frame through a folding rotating mechanism. The support protection device canprotect a radar in transit against the scratching by foreign objects. An L-shaped protective support plate can support the back of a radar array antenna when the radar is unfolded to operate, therebyreducing the shaking of the radar and improving the stability of a radar transmission signal. By an angle rotation mechanism, the upper array antenna can be automatically fixed when rotating to an appropriate position to operate or folded to an appropriate angle to contract. The upper array antenna has a slow and stable rotation speed and high angle adjustment precision.

Description

technical field [0001] The invention relates to the field of antenna array radar, in particular to a folding device for a vehicle-mounted high-mobility large antenna array radar. Background technique [0002] With the development of electronic technology and the needs of modern warfare, military radar antennas on the bottom surface are getting bigger and bigger, and the area of ​​large-scale antenna array radars is also getting bigger and bigger, and the mobility requirements are getting higher and higher. Quick response capability and battlefield survivability have a decisive impact. Especially when the radar is transported by rail, if the radar does not need to use external force to separate the top-loading equipment from the transport vehicle and can go straight onto the flatbed, the mobility of the radar equipment will be greatly improved. [0003] With the popularity and development of air transportation, aviation is increasingly being used as the first choice for fast...

AI Technical Summary

Problems solved by technology

[0006] (1) When the existing high-mobility large-scale radars are transported, because the functions of radar receiving and transmitting signals can be realized on the vehicle, there is generally no bucket roof on the transport vehicle. When transporting the radar, due to the radar’s There is no protection on the top and sides, so the radar is easily damaged by being scratched by branches, walls, protrusions on the road, etc., and the radar is also eroded by sand and dust, which reduces the service life of the radar;

[0007] (2) The unfolding and folding of the foldable radar is driven by the oil cylinder, so the accuracy of the rotation angle is not high
