The technical solution of the utility model is: aerological sounding radar antenna, phased electricity are swept little band plate antenna unit, adopt 4 rectangular microstrip plate aerials, connect and compose the weather search radar antenna of whole rectangle.
The utility model adopts the angle measurement of phase-interferometer principle, the weight of antenna assembly is less than 200kg, parts use the quick lock in mechanical hook-up, be divided into several portable unit, being provided with hydraulic pressure and electrical equipment control combines and sets up, utilizes the coordinate conversion technology automatically, the television monitoring technology improves demarcation speed, improves operation automation.
The utility model adopts integrated, miniaturization Design, overcomes that aerological sounding equipment volume in the past is big, the problem of Heavy Weight; And improve radio theodolite and hang down elevation angle serviceability.Key is that the phased electricity of small design high-performance is swept little band plate antenna unit, improves the low elevation angle and surveys the wind performance, dwindles the antenna assembly volume and weight, can improve motor-driven and cross-country power with system loading on light military IVECO offroad vehicle; Design novel hydraulic and electrical equipment control combine to set up automatically, remove and receive antenna and improve and set up, remove receipts speed.Utilize the coordinate conversion technology, the television monitoring technology improves demarcation speed, improves operating automation degree, develops a miniaturization aerological sounding system easy for operation, that practicality is reliable, mobility is good.
The utility model effect is obvious, is a kind of performance height, volume is little, in light weight, building and withdrawing speed is fast, cross-country power is strong weather radar system.
Compared with prior art, its remarkable advantage is:
1) adopt phased electricity to sweep little band plate antenna unit, antenna adopts 4 rectangular microstrip plate aerials, this kind array antenna volume is little in light weight, performance is good, plate aerial is 1300 * 1100mm * 100mm, antenna assembly weight is less than 160kg, antenna lobe width levels≤9 °, orientation≤10 °, gain 〉=21dB, the minimum work elevation angle≤11 °, the design typification examination reaches 7.84 °, windfinding radar is loaded on the IVECO offroad vehicle first, handling capacity is strong, cross-country ability good, and radar was significantly increased more in the past.
2) receipts of setting up, remove of antenna only need a button to finish automatically for 30 seconds, and are quick, safe, hidden, and not only reduced the building and withdrawing personnel, and significantly reduced and set up, remove between the time receiving, be that any in the past weather search radar is beyond one's reach.
3) adopt level meter coordinate conversion technology, system does not want leveling and just can start working, adopt the low-light level television surveillance technology, can make things convenient for night work in clear sky, rainy day all weather operations, easy and simple to handle, significantly reduced sounding personnel's labour intensity, in the motor-driven meteorological support of reality, the weather data that provides, data is promptly and accurately credible, has been subjected to user's favorable comment.

Rectangular microstrip plate aerial 1, little band plate aerial 2 of whole rectangle, vehicle 3, antenna holder 4.
Embodiment
Embodiment is as follows: referring to Fig. 1 and Fig. 2, the aerological sounding radar antenna adopts phased electricity to sweep little band plate antenna unit, and antenna adopts 4 rectangular microstrip plate aerials, connects and composes the weather search radar antenna of whole rectangle.Plate aerial inside is divided into four unit, and that four unit divide is upper left, upper right, the square arrangement of lower-left, bottom right.It is rectangular arranged.
Above-mentioned each unit contains 16 little belt unit.
For the ease of entrucking, the size of design is that the phased electricity of 1.3 * 1.1m is swept little band plate aerial, the march state antenna is droped to the ground at roof, antenna forms the wave beam upper and lower, left and right by coding control phase shifter and sweeps tracking signal partially, receiver only needs a passage, volume is little, and is in light weight, is loaded in the antenna pedestal.The little stepper motor of volume is selected in driving for use, driver module and planetary reduction gear, and at output torque, noise efficient, radially, and axially loaded, key indexs such as life-span precision are all very advanced; Angular measurement sensor is selected the high rotary transformer of precision for use, has saved synchronous gear gear transmission system, and volume is little in light weight, is easy to install; Gas gas bullet balance is adopted in the pitching transmission, has changed the mode of traditional dependence balancing weight balance, has dwindled the antenna assembly volume and weight, and the entire antenna device is less than 160Kg, and antenna assembly is neat, attractive in appearance.
In the setting up of radar antenna in the past; Most of VTOL (vertical take off and landing) mode that adopts, the lifting transmission has hydraulic pressure or screw mandrel dual mode, and the time of generally setting up is all about 8 minutes, and the hydraulic system volume is big, and Heavy Weight is not suitable for being loaded on the Light-duty Vehicle.Designed brand-new hydraulic control mode for this reason, radar antenna is when vehicle ', drop to the ground and be locked on the vehicle top, radar sets up to be removed receipts and realizes by hydraulic pressure, spread receipts and need to form from setting up to: when setting up by following job step, at first be to unclamp for sleeping in the put latch mechanism of radar antenna when vehicle ', hold up radar antenna then, again by erectting latch mechanism locking to duty.Spread the time receiving, unclamp the latch mechanism that radar antenna is erect earlier, the radar antenna that fell then, locking is crouched and is put latch mechanism again.
Set up and spread the job step of receipts according to above-mentioned radar antenna, adopt hydrostatic transmission and program in conjunction with realizing control.Hydraulic jack is as power, realizes control by the programmed control solenoid valve, and radar antenna is respectively pressed electrical appliance button one time setting up and spread in the receipts, just can finish the overall process of setting up and spreading receipts.Set up and remove between the time receiving in 30 seconds.General structure is little, and mechanism is simple, and control programization is simple to operate, dependable performance.
Fixed position relation according to radar and vehicle has designed the vehicle horizontal attitude sensor, and the heel of sense vehicle and trim value utilize the coordinate conversion technology to be converted into the true bearing elevation angle of radar, have simplified calibration process, have improved operating automation degree.
