Embodiment 1

[0030] combined with figure 1 and figure 2 As shown, an active radar seeker assembly test device includes:

[0031] The test dark box 1 constitutes a closed space. The test dark box 1 includes a shell, and an inner side of the shell is provided with a shielding interlayer 7, and a radome 15 is embedded and installed on the inner side of the outer shell opposite to the shielding interlayer 7. The radome 15 There is an antenna inside; the window design in the middle of the shielding interlayer 7 is used to send and receive signals between the receiving / transmitting horn 3 and the active radar seeker to ensure the moving distance of the receiving / transmitting horn 3, and a target simulation is placed in the shielding interlayer 7. device 4, the receiving / transmitting horn 3 is installed on the target simulator 4, so as to prevent the target simulator 4 support from reflecting electromagnetic waves and cause the active radar seeker to receive interference; the target simulator 4...

Embodiment 2

[0036] On the basis of Embodiment 1, the manual adjustment end includes a yaw knob 6 and a pitch knob 5, and the target simulator 4 also includes a first rotating rod, a second rotating rod, a first fixed block and a fixed connection with the receiving / transmitting horn 3 One end of the first rotating rod passes through the test dark box 1 and is connected to the yaw knob 6, and one end of the second rotating rod passes through the test dark box 1 and is connected to the pitch knob 5 , the first rotating rod is connected with the first fixed block for driving the first fixed block to translate in the horizontal direction; the first side of the second fixed block slides vertically with the first fixed block The connection can be realized through a vertical chute arranged on the first fixed block and a slider arranged on the second fixed block and engaged with the chute. The second side of the second fixed block is provided with a rack along the vertical direction, and the rack ...

Embodiment 3

[0042] On the basis of Example 1 or 2, in combination with figure 1 and figure 2 As shown, further, the radome 15 is a conical structure matched with the active radar seeker, and a circular hole 12 is provided on the side opposite to the inner side of the test dark box for matching with the conical structure. The radome 15 matches.

[0043] Further, anti-collision components are provided around the circular hole 12, and the anti-collision components are anti-collision rubber or sponge.

[0044] Further, combine image 3 As shown, it also includes a lifting car 9 for placing and fixing the test dark box, and the lifting car 9 is equipped with a steering wheel 10 with a locking structure. A level 13 is installed on the panel of the lifting car 9 for placing the test dark box.

Abstract

The invention discloses an active radar seeker general assembly testing device. The active radar seeker general assembly testing device comprises a testing camera obscura, a shielding interlayer is arranged on one inner side face of a shell of the testing camera obscura, an antenna housing is embedded in the other side face of the testing camera obscura, and an antenna is arranged in the antenna housing; a target simulator is placed in the shielding interlayer, and a receiving / sending loudspeaker is installed on the target simulator; the target simulator drives the receiving / sending loudspeaker to lift and translate, and a manual adjusting end hermetically penetrates through a shell of the testing camera obscura; the shielding interlayer is provided with a window; a wave-absorbing materialis adhered to the inner side surface of the shell; a signal source is placed outside the testing camera obscura, and the signal source is connected with the receiving / sending loudspeaker through a radio frequency cable which penetrates through the shell of the testing camera obscura in a sealed mode. The closed testing camera obscura is adopted, and disassembly and assembly are not needed; the wave-absorbing material and the shielding interlayer are arranged, so that external interference is avoided; and the target simulator is manually adjusted, so that the complexity of the system is reduced, and the maintainability is good.

Description

technical field [0001] The invention relates to the technical field of active radar seeker assembly testing, in particular to an active radar seeker assembly testing device. Background technique [0002] The active radar seeker will have strong electromagnetic radiation during the working process, so the tests during the development process are generally carried out in the microwave anechoic room, so that one can create an ideal test environment and prevent the seeker from being interfered. Can guarantee the personal safety of testers. Under normal circumstances, after the radar seeker is accepted by the overall weapon unit and assembled with the whole bomb, according to the test requirements of the overall missile unit, the technical status of the active radar seeker needs to be confirmed in the final assembly workshop and the technical position of the shooting range. . The general assembly workshop is generally not equipped with a corresponding darkroom for radar seeker ...
