Description
Technical field
The present invention relates to a kind of test system, particularly a kind of compact electromagnetic shielding test system.
Background technology
Traditional electromagnetic shielding test system is typically that room area typically exists, it is necessary to take a room in darkroom
10m2More than, the wall and door and window in room are both needed to cover using steel plate, to reach the effect of electromagnetic shielding, are also needed on the inside of steel plate
Absorbing material is pasted, to reduce the reflection of electromagnetic wave in darkroom, for large-scale darkroom, in its shielding properties and darkroom
ELECTROMAGNETIC REFLECTION performance is all very excellent, disclosure satisfy that the requirement of system testing, but because its position is fixed, can not move, and
And cost is very high, it is impossible to meets to guide first-class system in outfield or other places that can not build darkroom for system testing
Demand.
The content of the invention
Present invention aims at a kind of compact electromagnetic shielding test system is provided, solve existing test system cost height, account for
With volume it is big and irremovable the problem of.
A kind of compact electromagnetic shields test system, including：Antenna is tested, in addition to：Housing and suction wave plate.
The housing is made up of column part and round platform part, and wherein column part is the hollow Aluminum cylindrical of both ends open
Shape shell structure, round platform part are the semiclosed hollow aluminum shell structure that bottom end opening, top have aerial radiation mouth, round platform
Partial bottom and one end sealing welding of column part, the top end surface of round platform part have with testing antenna method orchid disk phase
The mounting hole matched somebody with somebody.
It is described to inhale the sheet rubber that wave plate is one-sided smooth, another side has equally distributed vertebra shape bulge-structure, wherein inhaling
The shiny surface of wave plate is pasted onto in inner walls and whole inwall is completely covered, and whole wave plate of inhaling passes through rivet and housing simultaneously
Inwall rivets；
The test antenna shares 2,2 test antennas be fixed on by mounting flange on the mounting hole of housing and with housing
Portion's cavity connection.
Test system is fixed in test system housing hollow in use, target seeker to be measured is installed on support, outside
Analog signal feed-in housing hollow, target seeker to be measured are received analog signal and carried out by supporting target simulator by testing antenna
Close beta, inhale wave plate and absorb unnecessary analog signal.
The system cost is relatively low, small volume, can move freely, can be provided for system testing needed for have shielding and
The test environment of electromaganic wave absorbing property.

It is described to inhale the sheet rubber that wave plate 3 is one-sided smooth, another side has equally distributed vertebra shape bulge-structure, wherein inhaling
The shiny surface of wave plate 3 is pasted onto on the inwall of housing 2 and whole inwall is completely covered, and whole wave plate 3 of inhaling is fixed on by rivet
On the inwall of housing 2.
The test antenna 1 shares 2, and 2 test antennas 1 are fixed on 8 mounting holes of housing 2 by mounting flange
And connected with the internal cavity of housing 2.
Test system is fixed in the cavity of test system housing 2, outside in use, target seeker to be measured is installed on support
The cavity of analog signal feed-in housing 2, target seeker to be measured are received analog signal by the supporting target simulator in portion by testing antenna 1
Close beta is carried out, wave plate 3 is inhaled and absorbs unnecessary analog signal.
