Abstract
The utility model relates to an antenna testing and rotating table with four freedom degrees, which is provided with a rotating mechanism that is rotated around a rotating shaft. A fixing device is arranged on the rotating mechanism. The antenna testing and rotating table with four freedom degrees is characterized in that a linear moving mechanism in three directions, that is to say, an X shaft, a Y shaft, and a Z shaft is also arranged simultaneously. A motive power machine and a driving device are arranged inside the moving mechanism. If motive power devices of the rotating mechanism and the moving mechanism are both connected with a computer, and a receiver of the antenna is also connected with the computer, the automatic control can be realized. Because the antenna testing and rotating table with four freedom degrees is provided with four freedom degrees, the height and the angle can be adjusted discretionally after the antenna which is prepared to be tested is fixed. The test of an antenna directional pattern is convenient and simple. The work efficiency of the test is improved.
Description
The utility model relates to a kind of testing apparatus, the four-degree-of-freedom antenna measurement turntable that uses during particularly a kind of test antenna.
Various antennas, comprise communication antenna, radar antenna, radio astronomical telescope antenna or other civil antenna, need test the parameter of its each side before use, wherein substantially the most also be to the most important thing is that antenna energy is in the spatial distributions situation, promptly test and draw out antenna pattern, main testing tool is the Antenna Pattern Measuring Test turntable.This turntable is provided with the rotating mechanism that rotates around rotating shaft, which is provided with fixtures such as anchor clamps.Earlier auxiliary antenna is fixed in the far-field region as transmitting antenna during use, antenna to be measured is fixed on the turntable with anchor clamps.Adjust the turntable height then, antenna to be measured is equated with the auxiliary antenna height, look for instrument to adjust the phase center of antenna to be measured in addition simultaneously, make it to be positioned on the rotating shaft of antenna rotating platform.This adjustment need be carried out repeatedly repeatedly, after knowing that error is very little, can carry out the measurement of antenna pattern.Because this traditional antenna rotating platform can only rotate, and promptly has only one degree of freedom, the position adjustment of other directions (as X-axis, Y-axis, Z axle) very difficulty is done, and uses very inconvenient.
The utility model will provide a kind of antenna rotating platform of new construction, it has four degrees of freedom in X-axis, Y-axis, Z-direction and around aspects such as rotating shaft rotations, after antenna to be measured is fixed on this turntable, its position can be gone up in any direction and be adjusted, be easy to aim at aspects such as height, directions between antenna to be measured and the auxiliary antenna, the relative position of antenna phase center to be measured and turntable rotating shaft also is easy to adjust, and the convenient test of antenna pattern is easily gone, and improves the operating efficiency of test.
The design's technical scheme is as follows; Identical with the traditional antenna turntable, antenna rotating platform is provided with the rotating mechanism that rotates around rotating shaft, which is provided with fixture, it is characterized in that: the linear moving mechanism that also is provided with X-axis, Y-axis and three directions of Z axle simultaneously.Promptly all around be respectively equipped with mechanical travel mechanism on three directions up and down.The travel mechanism of said rotating mechanism and three directions can be assembled together from bottom to up, the upper-lower position of four kinds of mechanisms can be intercoursed, but scheme is that rotating mechanism is placed below preferably, the travel mechanism that the Z axle is promptly adjusted height is located at the top, simultaneously a platform is set in the travel mechanism of the top again, fixture is installed on the platform.Said travel mechanism can be screw rod and nut; The mechanical translation mechanism that slide rail and slide block or track and wheel shaft etc. are commonly used.Translation mechanism can adopt manual approach, and also available motor-driven scheme promptly is provided with dynamic power machine, can be dynamic power machines such as motor, diesel engine.During with motor-driven scheme, need establish transmission device between engine and travel mechanism, transmission device can adopt transmission device commonly used such as belt, chain.During use antenna to be measured is fixed on the turntable of this four degrees of freedom, aims at auxiliary antenna substantially, adjust the Z axle earlier, promptly height is on the sustained height antenna to be measured and auxiliary antenna, and at this moment received signal is stronger.Before and after adjusting then (X-axis) with about (Y-axis), make signal reach maximum.Carry out the fine setting of angle simultaneously with rotating mechanism.Through two, three such adjustment, antenna is aimed at fully, and the maximum of picked up signal.The design's prioritization scheme is: the above-mentioned rotating mechanism and the power set of travel mechanism all and computer link, simultaneously the receiver of antenna also with computer link.The signal input computer of aerial receiver, computer moves or rotates with four kinds of mechanical mechanisms of intensity commander of the number of it is believed that, automatically antenna to be measured is aimed at auxiliary antenna.This programme can also be fixed on the far field with antenna to be measured in practicality; Auxiliary antenna is fixed on this turntable, and the direction of adjusting auxiliary antenna is aimed at both axis with the position.
The utility model provides a kind of antenna rotating platform of new construction, it has four degrees of freedom in X-axis, Y-axis, Z-direction and around aspects such as rotating shaft rotations, after antenna to be measured is fixed on this turntable, its height, position and angle all can go up in any direction and adjust, antenna to be measured is easy to aim at the axis of auxiliary antenna, the relative position of antenna phase center to be measured and turntable rotating shaft also is easy to adjust, and the convenient test of antenna pattern is easily gone, and improves the operating efficiency of test.
Now be described further with embodiment in conjunction with the accompanying drawings.
Fig. 1 is the utility model structural representation.
