Description

Technical Field

[0001] This patent relates to the field of signal simulation technology, specifically a dustproof radar signal simulator. Background Technology

[0002] The radar signal simulator can simulate multi-directional, multi-batch, multi-system, wide-band, high-precision, and highly realistic radar signals in real time. It can precisely simulate the variation characteristics of radar signals in the domain, time domain, and modulation domain; it can simulate conventional radar signals as well as pulse-wave, frequency-agile, continuous wave, and pulse Doppler radar signals.

[0003] However, existing radar signal simulators do not have a dustproof structure. Dust may accumulate on key parts of the simulator such as circuit boards and electronic components, affecting the transmission and processing of electronic signals. For example, dust covering the circuit board lines may cause slight changes in parameters such as capacitance and inductance between lines, thereby affecting the accuracy and stability of the signals generated by the radar signal simulator.

[0013] Compared with existing technologies, the beneficial effects of this patent are:

Detailed Implementation

[0020] The technical solutions of this patent embodiment will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this patent, and not all of them. Based on the embodiments of this patent, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this patent.

[0021] Please see Figure 1-3This patent provides a technical solution: a dustproof radar signal simulator, including a radar signal simulator host 1, which is electrically connected to an external power supply.

[0022] The radar signal simulator host 1 has an air inlet 2 on its side wall and a filter mechanism 3 installed on its side wall. The filter mechanism 3 can block the air inlet 2. The filter mechanism 3 includes a cover 31, a plug 32, a filter screen 33 and a frame 34. The plug 32 is installed on the side wall of the cover 31. The radar signal simulator host 1 has a connection hole 4 on its side wall. The plug 32 can be inserted into the connection hole 4. The frame 34 is installed on the side wall of the cover 31. The filter screen 33 is installed inside the frame 34. The cleaning mechanism 5 is installed on the lower wall of the frame 34.

[0023] By installing a filter mechanism 3 on the outside of the air inlet 2 of the radar signal simulator host 1, the incoming air can be filtered, thereby preventing dust from entering the interior of the radar signal simulator host 1 and causing dust to accumulate on the simulator's circuit boards, electronic components and other critical parts, affecting the transmission and processing of electronic signals.

[0024] The radar signal simulator host 1 proposed in this paper is existing technology. Its model is RMD type radar target signal simulator, which can generate multiple radar signals and complex modulated radar signals at the same time.

[0025] The side wall of the radar signal simulator host 1 is provided with an air outlet 6;

[0026] The filtered air enters the radar signal simulator host 1 through the air inlet 2, and the heat generated inside is carried away through the air outlet 6, thus completing the heat dissipation treatment of the radar signal simulator host 1 and preventing dust in the air from entering the radar signal simulator host 1.

[0027] Specifically, the cleaning mechanism 5 includes a baffle 51, a sliding plate 52 and a cleaning brush 53. The lower wall of the frame 34 is provided with a through groove 7. The baffle 51 is slidably installed in the through groove 7. The sliding plate 52 is slidably installed on the side wall of the baffle 51. The cleaning brush 53 is installed on the side wall of the sliding plate 52. The cleaning brush 53 can fit against the side wall of the filter screen plate 33.

[0028] By setting up the cleaning mechanism 5, the dust on the filter screen plate 33 can be cleaned, avoiding excessive dust that could affect the air intake and the heat dissipation effect of the device. At the same time, when the cleaning mechanism 5 cleans the filter screen plate 33, its baffle 51 can also separate the frame 34 from the cover 31 to prevent the swept dust from drifting into the cover 31.

[0029] The dust swept off by the cleaning brush 53 can be discharged through the channel 7 under the frame 34.

[0030] Specifically, a fan 8 is installed on the inner wall of the cover 31. The fan 8 is electrically connected to an external power source and can blow air into the air inlet 2.

[0031] Specifically, a sealing ring 9 is fitted to the outer side wall of the cover 31, and the sealing ring 9 can fit against the side wall of the radar signal simulator host 1.

[0032] Specifically, a rubber pad 10 is fitted to the side wall of the baffle 51, and the rubber pad 10 can fit against the inner side wall of the frame 34.

[0033] Specifically, magnets 11 are installed at the four corners of the frame 34. The magnets 11 can be attracted and connected to the side wall of the cover 31. A sealing gasket 12 is fitted to the side wall of the frame 34. The sealing gasket 12 can fit into the side wall of the cover 31.

[0034] Its frame 34 is installed on the cover 31 through the cooperation between the magnet 11 and the cover 31, so that the frame 34 can be removed from the cover 31 for easy cleaning of its fan 8.

[0035] Working principle: During the use of the radar signal simulator host 1, the fan 8 is turned on. Driven by the fan 8, the outside air passes through the filter plate 33 and enters the radar signal simulator host 1 through the air inlet 2, and the heat generated inside is carried away through the air outlet 6, thus completing the heat dissipation treatment of the radar signal simulator host 1.

[0036] To avoid affecting the air intake of this device, the filter screen 33 needs to be cleaned. During cleaning, first push the baffle 51 upward so that it separates the frame 34 from the cover 31 to prevent dust from entering the cover 31. Then, by sliding the sliding plate 52, it drives the cleaning brush 53 to move and clean the filter screen 33. The cleaned dust will be discharged through the through groove 7 under the frame 34.

[0037] It will be apparent to those skilled in the art that this patent is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this patent. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this patent is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this patent. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0038] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
