It can quantitatively measure the low-level microwave radiation of a target. In essence, a microwave radiometer is a high-sensitivity, high-resolution microwave receiver. However, in some cases where external influencing factors are significant, a radiometer signal enhancer needs to be connected to increase the signal strength.

[0023] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0024] Please refer to the following: Figures 1-5 A multi-channel millimeter-wave radiometer signal enhancer includes: a mounting plate 1, a multi-channel millimeter-wave radiometer 2, and a fixing mechanism;

[0025] A multi-channel millimeter-wave radiometer 2 and a signal enhancer 3 are fixedly mounted on the mounting plate 1. Multiple sockets 11 are provided on one side of the multi-channel millimeter-wave radiometer 2, each containing a second connection terminal 6. A wire 4 is connected to the signal enhancer 3, with one end of the wire 4 connected to a first connection terminal 5. One end of the first connection terminal 5 is inserted into a socket 11 and connected to the second connection terminal 6. A retaining ring 7 is fixedly fitted onto the first connection terminal 5. Each of the multiple sockets 11 contains a fixing mechanism connected to the retaining ring 7. The multi-channel millimeter-wave radiometer 2 includes an antenna, a waveguide coupler, a mixer, a microstrip low-pass filter, a multi-channel power divider, and multiple parallel output channels. A noise source is connected to the waveguide coupler, and a tunable local oscillator is input to the mixer. Compared to a fixed local oscillator, after inputting the tunable local oscillator, it can simultaneously detect up to [number missing] channels. The receiver originally had 8 detection channels, and the increased number is 8*n. If the original receiver had t detection channels, then after inputting a tunable local oscillator, it can simultaneously detect up to t*n channels, thus achieving simultaneous multiple frequency conversions. This increases the number of detection channels to n times the original number, thereby achieving the purpose of microwave measurement. The specific structure and working principle of the multi-channel millimeter-wave radiometer 2 can be found in the literature with application number 202320002627.5, which is existing technology and will not be elaborated further. The signal enhancer 3 is a CNNC FH1047A or a dedicated integrated chip (such as RENA3), etc. Different signal enhancers 3 can be replaced according to different usage environments. The signal enhancer 3 can increase the signal strength, which is existing technology and will not be elaborated further.

[0026] The fixing mechanism includes a rotating shaft 8, a fixing plate 9, and a torsion spring 10. The rotating shaft 8 is rotatably connected to multiple sockets 11. Through the cooperative design between the fixing plate 9, the fixing ring 7, the slot 14, the sockets 11, and the torsion spring 10, it can not only achieve the effect of quick assembly and disassembly between the multi-channel millimeter-wave radiometer 2 and the signal enhancer 3, but also prevent poor connection between the first connection terminal 5 and the second connection terminal 6. Moreover, when the first connection terminal 5 is pulled out, the socket 11 can be protected.

[0027] In this method, a fixing plate 9 is fixedly connected to the rotating shaft 8. The fixing plate 9 is engaged with the fixing ring 7. Through the interaction between the fixing plate 9 and the slot 14, the connection terminal 5 is limited and fixed.

[0028] In this method, a torsion spring 10 is fixedly sleeved on the rotating shaft 8. One end of the torsion spring 10 is fixedly connected to the multi-channel millimeter-wave radiometer 2. The fixed plate 9 is restored to its original state by the force of the torsion spring 10 and the transmission of the rotating shaft 8.

[0029] In this method, a slot 14 is provided on the fixing ring 7, and the fixing plate 9 is engaged with the slot 14 to facilitate the engagement between the fixing plate 9 and the fixing ring 7.

[0030] In this method, the multi-channel millimeter-wave radiometer 2 is provided with a storage groove 12, and the rotating shaft 8 rotates in the storage groove 12. The storage groove 12 is adapted to the fixing plate 9 and is used to store the fixing plate 9. The multi-channel millimeter-wave radiometer 2 is provided with a groove 13, which is adapted to the fixing plate 9. Both the groove 13 and the storage groove 12 correspond to the insertion hole 11. Through the action of the groove 13, the purpose of facilitating the rotation of the fixing plate 9 is achieved, and the fixing plate 9 is blocked and limited.

[0031] In this method, a groove 2 is provided on one side of the fixing plate 9, and a sealing gasket is fixedly installed in the groove 2. The sealing gasket is adapted to the insertion hole 11. The fixing plate 9 moves within the insertion hole 11, and the sealing gasket facilitates the sealing of the corresponding insertion hole 11 by moving left and right.

[0032] In this method, the bottom of the mounting plate 1 is provided with a support rod, and one end of the support rod is provided with a fixing seat for support and is detachably connected.

[0033] The working principle of the multi-channel millimeter-wave radiometer signal enhancer provided by this utility model is as follows:

[0034] In use, one end of the first connection terminal 5 is inserted into one of the multiple sockets 11 on the multi-channel millimeter-wave radiometer 2, and the first connection terminal 5 is connected to the corresponding second connection terminal 6. In this process, the slot 14 on the fixing ring 7 is first aligned with the fixing plate 9. During the insertion process, the fixing ring 7 and the fixing plate 9 act together, causing the fixing plate 9 to rotate around the pivot 8 at a certain angle, and causing the torsion spring 10 to rotate and store force. Then, when the slot 14 passes through the fixing plate 9, the elastic potential energy of the torsion spring 10 causes the fixing plate 9 to engage with the slot 14. At this time, through the interaction between the fixing plate 9 and the slot 14, the first connection terminal 5 is limited and fixed, thereby avoiding poor connection between the first connection terminal 5 and the second connection terminal 6.

[0035] When disassembling the connecting terminal 5, first rotate the connecting terminal 5 by a certain angle so that the slot 14 is disengaged from the fixing plate 9. During this process, the fixing ring 7 acts on the fixing plate 9 and pushes the fixing plate 9 into the storage slot 12, thereby releasing the purpose of limiting the fixing ring 7. After that, the connecting terminal 5 and the fixing ring 7 are pulled out from the corresponding socket 11, thereby achieving the effect of quick disassembly between the multi-channel millimeter-wave radiometer 2 and the signal enhancer 3.

[0036] At the same time, the force of the torsion spring 10 causes the fixing plate 9 to rotate around the pivot 8 at a certain angle, and the sealing gasket on one side of the fixing plate 9 comes into contact with the multi-channel millimeter-wave radiometer 2, thereby achieving the effect of sealing the socket 11 and preventing dust and debris from entering the socket 11.

[0037] Compared with related technologies, the multi-channel millimeter-wave radiometer signal enhancer provided by this utility model has the following beneficial effects: through the cooperation of various components, it can not only achieve the effect of quick disassembly and assembly between the multi-channel millimeter-wave radiometer 2 and the signal enhancer 3, but also avoid the effect of poor connection between the first connection terminal 5 and the second connection terminal 6. Moreover, when the first connection terminal 5 is pulled out, the socket 11 can be protected, which greatly improves the practicality.

[0038] The above are merely embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
