Description
Technical field
The present invention relates to phased-array radar field, spy is related to a kind of vehicle-mounted motor-driven large-scale antenna front radar of height.
Background technique
One of the core of the motor-driven Large Phased Array Radar design of vehicle-mounted height be exactly Radar Antenna Structure and its lifting, pitching,
Folded structure design, it is however generally that Large Phased Array Radar Antenna volume is larger, and (length and width more than 2.5 meters, when vehicle-mounted transport is needed
Assembled or folding is carried out to radar antenna), structure is complicated, and design requirement is high, especially also to meet high automobile-carried want
Ask (highway, railway transportation limitation), and meet radar rapid deployment removes receipts in use, this make radar antenna and its
Foldable structure layout must be compact, so design is it should be noted that following problem: (1) radar antenna is in the case where removing receipts state, it is necessary to full
The limitation of the conditions such as sufficient highway, railway transportation length, weight；(2) radar antenna passes through the drivers such as folding, lifting, pitching
After structure completes antenna array expansion, the center height of radar antenna must satisfy requirement of the radar to centre-height；(3) as height
Mobile radar, it is necessary to meet quickly expansion and remove receipts time requirement (the shorter accomplish to be unfolded or remove the better between the time receiving)；(4) must protect
Card antenna structure intensity, antenna expansion remove receive it is easy to operate.
It is by during development of radar structure system, using conventional design means that prior art means, which solve problem above,
And realize.Its disadvantage is as follows:
It is general to use " A " font or " n " word because the motor-driven Large Phased Array Radar Antenna of vehicle-mounted height is laid out limited space at present
Antenna array is mainly divided into two by type distribution, the distribution of " A " font from centre, and " A " font vertex is two pieces of antenna array
Antenna array can be flattened by fold mechanism, then by the luffing mechanism connecting with hinge joint, antenna is faced upward by hinge joint
It rises, to complete the expansion of radar, this " A " font mode disadvantage is exactly that front is not easy excessive, be easy to cause railway, public affairs
Road transport is defeated to transfinite, and the center of radar is high after pitching, under normal circumstances the lower performance for influencing radar, because structure limits general pitching
Mechanism is single-screw mandrel support construction, and when antenna arrays of radar works and rotates, stability is poor；The distribution of " n " font is mainly by day
Linear array face is divided into three pieces, and " n " font upper horizontal face is generally main piece of three pieces of antenna piecemeals, and two vertex are respectively two lateral mass and master
Antenna array can be flattened by fold mechanism, then by the luffing mechanism connecting with main piece, antenna is faced upward by the hinge joint of block
It rises, to complete the expansion of radar, this " n " font disadvantage is exactly that structure is complicated, to antenna array requirement on machining accuracy
It is higher, remove when receipts state that shared vehicle-mounted space is larger, vehicular platform space utilization rate is lower.
At present it is not yet found that closing the technical literature for solving problems.
Summary of the invention
In view of the deficiencies of the prior art, present invention optimizes Radar Antenna Structures, using " L " type antenna arrangement, and lead to
It crosses folding, pitching, lift three-level symmetrical expression double lead drive mechanism, cooperation servo-control system (including servomotor, gear reducer
Deng) design, make radar antenna in the case where meeting highway, railway transportation restrictive condition, have the characteristics that rapid deployment and to remove receipts.
The technical scheme is that a kind of vehicle-mounted motor-driven large-scale antenna front radar of height, including chassis vehicle, work are put down
Platform, revolving platform, excessive bracket, lower antenna array and upper antenna array, workbench is fixed on a chassis, and revolving platform passes through spiral shell
Nail is fixed on workbench middle front part, it is characterised in that: the excessive bracket is connect by lifting mechanism with revolving platform；Excessively
Bracket is connect by luffing mechanism with lower antenna array；Lower antenna array is connect by fold mechanism with upper antenna array, is folded
After mechanism folds, lower antenna array and upper antenna array are in the shape of " L " font, after fold mechanism expansion, lower antenna array with
Upper antenna array is in the same plane.
According to the vehicle-mounted motor-driven large-scale antenna front radar of height as described above, it is characterised in that: the lower antenna array
Divide with upper antenna array in antenna narrow side, the width of lower antenna array is less than chassis vehicle width of the carbody.
The present invention has the advantages that compared with prior art
Under conditions of meeting highway, railway transportation limitation, optimize Large Phased Array Radar Antenna is structurally reasonable
Design, makes full use of the space of chassis vehicle, compact layout, and structure is simple.The present invention improves under conditions of meeting vehicle-mounted requirement
The high maneuverability of radar entirety, reduces the volume of radar, reduces production cost.
