Description
Technical field
The utility model belongs to remote measurement Electromagnetic Interference and absorption techniques field, is specifically related to the waveguide of a kind of telemetry system wireless transmission.
Background technology
Before the MISSILE LAUNCHING, generally guided missile is vertically placed, the bullet head-shield is covered bullet, then they are put into vertical placed metal system guided missile launching tube.In the test process before MISSILE LAUNCHING, the outside electromagnetic signals of transmitter of installing in the bullet receives electromagnetic wave signal by receiving antenna, thereby reaches the purpose of wireless transmission.Yet the bullet head-shield is electromagnetic wave transparent material not, and launch canister has certain shielding action except that one section of tube port position is that all the other are metal material the electromagnetic wave transparent material to wireless transmission.In addition, in the bullet head-shield, there is clutter, disturbed the transmission of useful signal, bring difficulty for the warhead telemetry system testing, make on the bullet that ground receives the electromagnetic wave signal quality low, poor accuracy.
The utility model content
The purpose of this utility model provides a kind of telemetry system wireless transmission waveguide that improves warhead telemetry system wireless transmission electromagnetic wave signal accuracy rate.
The utility model is achieved in that
The waveguide of a kind of telemetry system wireless transmission, it comprises bearing and inhales the ripple tube; Described bearing is that metallic is cylindric, has axially extending bore in its bottom surface; Inhale the ripple tube and be installed in bearing inside, the tubular body that it is made for the foam Electromagnetic Wave Absorbing Plate, the internal diameter of its outer dia and bearing is complementary.
Bearing is installed on the guided wave mouth of bullet head-shield by flange as mentioned above.
Aforesaid metal is aluminium alloy, titanium alloy or alloy steel.
Aforesaid foam Electromagnetic Wave Absorbing Plate is electromagnetic wave attenuation 15dB when the electromagnetic wave signal of transmission 2.2GHz～9.4GHz.
Waveguide of telemetry system wireless transmission and transmitter are positioned on the same surface level as mentioned above, and are on the line of the center of circle of this bullet xsect by transmitter and transmitter; Receiving antenna and the waveguide of telemetry system wireless transmission and transmitter are placed on the sustained height, and the three is on the same straight line.
The beneficial effects of the utility model are:
The utility model adopts the waveguide of telemetry system wireless transmission, with on the bullet head-shield and the guided wave interruption-forming transmission channel on the launch canister.The electromagnetic wave signal that axially transmits along transmission channel directly is received the antenna reception through transmission channel; The electromagnetic wave signal that has angle incident to inhale ripple tube inboard is imported into absorbing material attenuation by absorption; The electromagnetic wave signal that has angle incident to inhale the ripple tube outside is reflected, and prevents that it from entering transmission channel, has the electromagnetic wave signal in the angle incident bearing outside to be reflected, and prevents that it from entering transmission channel.Thereby, greatly reduce of the interference of the interior invalid electromagnetic wave signal of bullet head-shield to effective electromagnetic wave signal, improved the transmission accuracy rate of electromagnetic wave signal.

Embodiment
Waveguide is introduced to a kind of telemetry system wireless transmission of the present utility model below in conjunction with drawings and Examples:
As shown in Figure 1, 2, the waveguide of a kind of telemetry system wireless transmission comprises bearing 8 and inhales ripple tube 9.Described bearing 8 is that metallic is cylindric, has axially extending bore in its bottom surface, and it is installed on the guided wave mouth 5 of bullet head-shield 3 by flange 10.Inhale ripple tube 9 and be installed in bearing 8 inside, the tubular body that it is made for the foam Electromagnetic Wave Absorbing Plate, the internal diameter of its outer dia and bearing 8 is complementary.Above-mentioned metal is aluminium alloy, titanium alloy or alloy steel, is preferably aluminium alloy.Above-mentioned foam Electromagnetic Wave Absorbing Plate is electromagnetic wave attenuation 15dB when the electromagnetic wave signal of transmission 2.2GHz～9.4GHz such as 2.2GHz, 5GHz and 9.4GHz.
As shown in Figure 3, when above-mentioned telemetry system wireless transmission waveguide 4 is installed, will inhale ripple tube 9 bearing 8 of packing into earlier, then bearing 8 will be installed on the bullet head-shield 3 by flange 10.Telemetry system wireless transmission waveguide 4 is positioned on the same surface level with transmitter 2 in the bullet 1, and is on the line of the center of circle of this bullet 1 xsect by transmitter 2 and transmitter.Position in bullet head-shield 3 and launch canister 6 correspondences has the guided wave mouth 5 that is complementary with telemetry system wireless transmission waveguide 4, is used to transmit electromagnetic wave signal.Receiving antenna 7 and waveguide 4 of telemetry system wireless transmission and transmitter 2 are placed on the sustained height, and the three is on the same straight line.
During work, the transmitter 2 in the bullet 1 outwards sends electromagnetic wave signal, and electromagnetic wave signal sends to receiving antenna 7 by the transmission channel that guided wave mouth 5 forms.Wherein, the electromagnetic wave signal that axially transmits along transmission channel directly is received antenna 7 receptions through transmission channel; The electromagnetic wave signal that has angle incident to inhale ripple tube inboard is imported into absorbing material attenuation by absorption; The electromagnetic wave signal that has angle incident to inhale the ripple tube outside is reflected, and prevents that it from entering transmission channel, has the electromagnetic wave signal in the angle incident bearing outside to be reflected, and prevents that it from entering transmission channel.
Thus,, greatly reduce of the interference of bullet head-shield 3 interior invalid electromagnetic wave signals, improved the transmission accuracy rate of electromagnetic wave signal effective electromagnetic wave signal by using telemetry system wireless transmission waveguide 4.
