Abstract
The invention relates to a cage type movable testing support of a satellite navigation airspace antijam receiver, which is characterized by comprising an annular bottom bracket, a plurality of arc brackets and a side bracket, wherein one ends of the arc brackets are centrally connected with one end of the side bracket, the other ends of the arc brackets are uniformly distributed and connected to the circumference of the annular bottom bracket in a sliding manner, and the other end of the side bracket is fixedly connected to the circumference of the annular bottom bracket. The invention overcomes the defects of the traditional support rod, and has the advantages that space actual positions of all satellite signals and interference signals can be simulated, an incident angle is conveniently regulated, and incident power is simply calibrated, and no repeated calibration is used when the incident angle is changed.
Description
Technical field
The present invention relates to a kind of cage-type moving testing support for airspace anti-interference receiver in satellite navigation, belong to the Satellite Navigation Technique field, can be applied to satellite navigation antijam receiver test macro.
Background technology
At present all very simple to the indoor wireless proving installation of spatial domain antijam receiver, usually adopt installation testing antenna on support, emissioning testing signal.The tested receiver antenna is placed in the middle of the test site, and the undesired signal emitting antenna is installed on the pole on every side of place.Emitting antenna setting height(from bottom) and pole have determined the incident angle of the relative receiver antenna plane of undesired signal apart from the distance of tested receiver antenna.The satellite navigation signals of simulating for test is sent by the receiver antenna top, and the navigation signal of all satellites is sent by an antenna.
The shortcoming of this proving installation is:
1, in practice, the signal of different navigation satellite is sent from different perspectives by each satellite, is sent by an antenna and test used analog satellite navigation signal, and test result can not reflect actual conditions fully.
2, the undesired signal incident angle is regulated limited.
3, test signal arrives the power calibration difficulty of antenna.
Summary of the invention
The technical matters that solves
For fear of the deficiencies in the prior art part, the present invention proposes a kind of cage-type moving testing support for airspace anti-interference receiver in satellite navigation, has overcome the defective of existing pole.
Technical scheme
A kind of cage-type moving testing support for airspace anti-interference receiver in satellite navigation is characterized in that comprising bottom circle ring rack 1, some arc supports 2 and side stand 3; One end of some arc supports 2 is concentrated with an end of side stand 3 and is connected, and the even branch of the other end is slidingly connected on the circumference of bottom circle ring rack 1, and the other end of side stand 3 is fixedly connected on the circumference of bottom circle ring rack 1.
When the navigation satellite signal of simulating whole sky and undesired signal, the center of circle angle of arc support
It is 90 °.
When the antijam receiver carrier is aircraft, guided missile etc., interference source with respect to carrier when the negative altitude angular direction, the center of circle angle of arc support
It is 100 °.
Described arc support 2 adopts pulley, universal wheel or ball with being slidingly connected of bottom circle ring rack 1.
Described bottom circle ring rack 1 is with slide rail.
Described arc support 2, bottom circle ring rack 1 and side stand 3 adopt electromagnetic wave transparent material.
Beneficial effect
A kind of cage-type moving testing support for airspace anti-interference receiver in satellite navigation that the present invention proposes has overcome the defective of existing pole, has following advantage:
1. can simulate the space physical location of all satellite-signals and undesired signal.
2. incident angle is easy to adjust.
3. incident power is demarcated simply, when incident angle changes, does not need repeatedly to demarcate.

Embodiment
Now in conjunction with the embodiments, the invention will be further described for accompanying drawing:
Test bracket is comprised of bottom circle ring rack, arc support and side stand three parts (Fig. 1, Fig. 2), and arc support can slide along the bottom circle ring rack.During use, the home position of bottom circle ring rack is placed tested antijam receiver antenna.Installation testing emitting antenna on the arc support, emitting antenna can move up and down along arc support.
Arc support can have many, and during use, each support can be installed one or more antennas, simulates one or more navigation satellite signals or undesired signal (Fig. 3, Fig. 4 and Fig. 5).Azimuth angle alpha and elevation angle γ by regulating each antenna can simulate navigation satellite signal and the undesired signal of arbitrary orientation.Because tested antenna is positioned at the arc support home position, therefore when regulating antenna azimuth α and elevation angle γ, the transmit signal power that arrives tested antenna is constant, has so just avoided the repeatedly process of demarcation signal.
Side stand and arc support adopt wood materials, make its impact on electromagnetic transmission minimum.The bottom circle ring rack adopts aluminum alloy materials, is convenient to processing.
Side stand is column type, and diameter is 15cm, highly is 3.5 meters.
The arc support cross section is 7.5cm7.5cm, and radius is 3 meters.Can slide along the bottom circle ring rack with wheel in the arc support bottom, see Fig. 1, Fig. 9.
The radius of bottom circle ring rack is 3 meters, and the bottom circle ring rack is with slide rail, and arc support can slide along the bottom circle ring rack, and carriage is pulley, universal wheel, ball etc.But the junction, top of arc support and side stand is flexible rotating also, sees Fig. 1, Fig. 8.
Test is connected with emitting antenna and matrix anchor clamps, and the spill chucking position can move up and down along arc support, regulates, and passes through fastened by screw.
Arc support is connected the junction, top and is adopted ball bearing to connect with side stand, be convenient to slide.
The effect of bottom circle ring rack has:
1. provide the bottom stabilizing base for whole device.
2. provide sliding rail for arc support.
The effect of side stand is to support arc support.
Whole device comprises that arc support, bottom circle ring rack and side stand are made of electromagnetic wave transparent material.Guarantee that whole device can not affect signal and propagate warranty test result's credibility.
For navigation satellite signal and the undesired signal of simulating whole sky, the angle of arc support
Be at least 90 °, see Fig. 6.When the antijam receiver carrier was aircraft, guided missile etc., interference source in the negative altitude angular direction, therefore needed to increase angle with respect to carrier
Representative value is 100 °, sees Fig. 7.
