Description

Technical Field

[0001] This invention belongs to the field of on-orbit antenna technology, and particularly relates to a microwave emissivity testing device, testing method, equipment, and storage medium for a radiometer antenna. Background Technology

[0002] Large-aperture microwave radiometers (LAMs) are geostationary microwave payloads. They acquire regional atmospheric temperature and humidity profiles under typhoon, precipitation, thick cloud, thin cloud, and clear-sky conditions through high-frequency monitoring of the atmosphere and clouds, improving the accuracy of weather analysis and forecasting, especially nowcasting and regional numerical weather prediction. They also provide high-frequency, three-dimensional monitoring of high-impact weather events such as typhoons and severe convection, supporting meteorological disaster early warning and secondary disaster prediction. Real-time dynamic monitoring of heavy precipitation, floods, high temperatures, and cold waves provides information services for ecological and environmental monitoring and management. Furthermore, by generating various atmospheric physical parameters and quantitative products, they provide services for agriculture, aviation, aerospace, marine, and water conservancy sectors. Whether a large-aperture microwave radiometer can acquire valuable data and achieve quantitative applications and actual operational use during on-orbit operation depends primarily on its accurate calibration.

[0003] Existing spaceborne microwave radiometers operate in sun-synchronous orbits with a period of 98 minutes, meaning they undergo a complete thermal cycle every 98 minutes. This limited cooling and heating results in a small temperature range, with the antenna experiencing temperature variations of approximately -90°C to 90°C. In contrast, geostationary orbits have a period of 24 hours, meaning they undergo a complete thermal cycle daily, with ample exposure to both sunlight and darkness, leading to extreme temperature differences. When operating in geostationary orbit, the antenna's front must be completely exposed to the outer space environment due to the nature of microwave detection missions, continuously receiving periodic sunlight. The external heat flow environment is complex, with temperatures ranging from -150°C to 130°C, and surface temperature differences exceeding 200°C. The antenna structure undergoes large-scale thermal deformation due to these drastic temperature changes, necessitating novel thermal control coating technologies to reduce the magnitude of thermal deformation. The microwave heat loss caused by the thermal control coating affects the system's calibration accuracy. To meet the quantitative application requirements of microwave radiometers in orbit, high-precision microwave emissivity measurements are necessary.

[0004] The main challenge in accurately correcting microwave thermal loss of antennas is the high frequency band required for microwave emissivity testing and the high testing accuracy required. Summary of the Invention

[0005] The purpose of this invention is to provide a radiometer antenna microwave emissivity testing device, testing method, equipment, and storage medium that can accurately obtain the emissivity of a cascaded thermal control coating sample.

[0006] To solve the above problems, the technical solution of the present invention is as follows: a microwave emissivity testing device for a radiometer antenna, comprising: a first cascaded thermal control coating test piece, a second cascaded thermal control coating test piece, a vacuum high-temperature radiation source, a vacuum low-temperature radiation source, a vacuum variable-temperature radiation source, a receiving component, a position control mechanism, and a temperature controller. The first cascaded thermal control coating test piece and the second cascaded thermal control coating test piece are disposed inside the temperature controller. The receiving component is disposed on the position control mechanism. The position control mechanism controls the receiving component to periodically reach a predetermined position to receive signals emitted by the vacuum high-temperature radiation source, the vacuum low-temperature radiation source, and the vacuum variable-temperature radiation source in a time-division manner. The signals emitted by the vacuum variable-temperature radiation source include signals that pass through and do not pass through the first cascaded thermal control coating test piece and the second cascaded thermal control coating test piece.

The first temperature controller and the second temperature controller are used to control the temperature of the first cascaded thermal control coating test piece and the second cascaded thermal control coating test piece and to provide feedback on the current temperature.

[0009] In one embodiment of the present invention, the receiving component includes a parabolic reflector and a receiving device, the receiving device receiving a radiation source signal through the parabolic reflector, and the receiving device includes a receiver and a feed horn.

[0010] In one embodiment of the present invention, the parabolic reflector forms a plane wave, and the parabolic reflector receives the microwave radiation signal reflected by the thermal control coating at an incident angle of 45°.

[0011] In one embodiment of the present invention, the first cascaded thermal control coating sample and the second cascaded thermal control coating sample are two auxiliary coatings for the thermal control coating of the reflector surface of a large-aperture microwave radiometer.

[0012] In one embodiment of the present invention, the testing device further includes a precision temperature control device, which can acquire the loss values ​​of multiple sets of cascaded thermal control coating test pieces at different temperatures.

[0013] Based on the same inventive concept, this invention provides a method for testing the microwave emissivity of a radiometer antenna, comprising the following steps: driving the receiving component to rotate via a position control device, the receiving component receiving microwave radiation from a vacuum high-temperature radiation source and a vacuum low-temperature radiation source at different times, recording the output voltage of the receiving component, and establishing a two-point calibration equation; driving the receiving component to rotate via a position control device, the receiving component receiving microwave radiation from a vacuum variable-temperature radiation source at different times, without passing through the cascaded thermal control coating test piece and with passing through the cascaded thermal control coating test piece, recording the output voltage of the receiving component, and eliminating the nonlinear error of the receiving component; controlling the temperature of the cascaded thermal control coating test piece to T using a temperature controller. OH T OM T OL The output voltage of the receiving component was recorded, and the microwave loss values ​​of the three sets of cascaded thermal control coating test pieces were calculated. Based on the microwave loss values ​​of the three sets of cascaded thermal control coating test pieces, the microwave emissivity at an incident angle of 45° was calculated, and the microwave emissivity at any angle on the reflecting surface was further extrapolated.

[0014] Based on the same inventive concept, the present invention provides an electronic device, comprising: a memory for storing a processing program; and a processor for implementing the radiometer antenna microwave emissivity testing method when executing the processing program.

[0015] Based on the same inventive concept, the present invention provides a readable storage medium storing a processing program, which, when executed by a processor, implements the radiometer antenna microwave emissivity testing method.

[0016] Because the present invention adopts the above technical solution, it has the following advantages and positive effects compared with the prior art:

[0017] 1. In this embodiment of the invention, the receiving component observes the same vacuum variable-temperature radiation source with and without passing through the cascaded thermally controlled coating test piece, eliminating the nonlinear error of the receiving component; a parabolic reflector is used to form a plane wave that irradiates the cascaded thermally controlled coating test piece at a 45° incident angle, eliminating the influence of inconsistent incident angles caused by beam diffusion; the thermally controlled coating test piece is used for precise temperature control, and the loss value of the cascaded thermally controlled coating test piece under different temperature conditions is obtained.

Detailed Implementation

[0026] The following detailed description, in conjunction with the accompanying drawings and specific embodiments, provides a more comprehensive understanding of the microwave emissivity testing device and method for a radiometer antenna proposed in this invention. The advantages and features of this invention will become clearer from the following description and claims.

[0027] See Figures 1 to 4This invention provides a microwave emissivity testing device for a radiometer antenna, comprising: a first-cascaded thermally controlled coating test piece 22, a second-cascaded thermally controlled coating test piece 21, a vacuum high-temperature radiation source 4, a vacuum low-temperature radiation source 5, a vacuum variable-temperature radiation source 3, a receiving component 1, a position control mechanism 6, and a temperature controller. The receiving component 1 is mounted on the position control mechanism 6, which controls the receiving component 1 to periodically move to a predetermined position to receive signals emitted by the vacuum high-temperature radiation source 4, the vacuum low-temperature radiation source 5, and the vacuum variable-temperature radiation source 3 in a time-division manner. The signals emitted by the heat radiation source 3 include signals that pass through and do not pass through the first cascaded thermal control coating sample 22 and the second cascaded thermal control coating sample 21; the temperature controller includes a temperature control box 23 that houses the first cascaded thermal control coating sample 22 and the second cascaded thermal control coating sample 21, and a first temperature controller 25 and a second temperature controller 24 respectively disposed on the first cascaded thermal control coating sample 22 and the second cascaded thermal control coating sample 21; the receiving component 1 includes two parts: a parabolic reflector 12 and a receiver and a feed horn 11, and the receiver and the feed horn 11 receive signals through the parabolic reflector 12.

[0028] The receiving component receives signals in a 1-minute time division ratio, forming the following signal channels:

[0029] First signal channel: Vacuum high-temperature radiation source 4 → Receiving component 1;

[0030] Second signal channel: Vacuum cryogenic radiation source 5 → Receiving component 1;

[0031] Third signal channel: Vacuum temperature-variable radiation source 3 → Receiving component 1;

[0032] Fourth signal channel: Vacuum variable temperature radiation source 3 → First cascade thermal control coating test piece 22, Second cascade thermal control coating test piece 21 → Receiving component 1.

[0033] A two-point calibration equation is established by using the output voltages of the first and second signal channels. Based on the two-point calibration equation and the output voltages of the third and fourth signal channels, the nonlinear error of the receiving component 1 is eliminated, and the loss values ​​of the cascaded thermal control coating test pieces 22 and 21 are obtained. A parabolic receiving component is used to form a plane wave convergence, and the microwave radiation of the cascaded thermal control coating test piece is received at an incident angle of 45° to eliminate the test error caused by inconsistent incident angles. A temperature controller is used to precisely control the temperature of the thermal control coating test piece at three sets of temperatures, and the output voltage values ​​under the three states are tested. This eliminates background environmental interference and thus accurately obtains the emissivity test value of the cascaded thermal control coating test piece.

[0034] This invention features a simple and compact structure. It utilizes the receiving component to observe the same vacuum variable-temperature radiation source with and without passing through a cascaded thermally controlled coating test piece, eliminating nonlinear errors in the receiving component. A parabolic reflector is used to form a plane wave that irradiates the cascaded thermally controlled coating test piece at a 45° incident angle, eliminating the influence of inconsistent incident angles caused by beam diffusion on the test results. Precise temperature control of the thermally controlled coating test piece is employed to obtain three sets of loss values ​​for the cascaded thermally controlled coating test piece at different temperatures. Through an error correction method, the emissivity of the cascaded thermally controlled coating test piece is accurately obtained. This test result can be used for microwave emissivity at any incident angle on the reflector surface, solving the engineering problem of inaccurate emissivity testing for large-aperture antennas in the terahertz band.

[0035] See Figure 5 Based on the same concept, this invention also provides a method for testing the microwave emissivity of a radiometer antenna, comprising the following steps: rotating the receiving component 1 via a position control device 6; receiving the microwave radiation 5 from a vacuum high-temperature radiation source 4 and a vacuum low-temperature radiation source at different times; recording the output voltage of the receiving component 1 and establishing a two-point calibration equation; rotating the receiving component 1 via the position control device 6; receiving the vacuum variable-temperature radiation source at different times, without passing through the cascaded thermal control coating test piece and after passing through the cascaded thermal control coating test piece; recording the output voltage of the receiving component 1 and eliminating the nonlinear error of the receiving component 1; and controlling the temperature of the cascaded thermal control coating test piece to T using a temperature controller. OH T OM T OL The output voltage of the receiving component was recorded, and the microwave loss values ​​of the three sets of cascaded thermal control coating test pieces were calculated. Based on the microwave loss values ​​of the three sets of cascaded thermal control coating test pieces, the microwave emissivity at an incident angle of 45° was calculated, and the microwave emissivity at any angle on the reflecting surface was further extrapolated.

[0036] Specifically, it includes:

[0037] Step S1: Drive the turntable 6 to rotate, and the receiving component 1 receives the vacuum high-temperature radiation source 4, recording the radiance R of the vacuum high-temperature radiation source. h Receiver component output voltage V h .

[0038] Step S2: Drive the turntable 6 to rotate, and the receiving component 1 receives the vacuum cryogenic radiation source 5, recording the radiance R of the vacuum cryogenic radiation source. c Receiver component output voltage V c .

[0039] Step S3: Establish the two-point calibration equation through steps S1 and S2, and obtain the coefficients of the two-point calibration equation.

[0040]

[0041] Step S4: Drive the turntable 6 to rotate, receive the vacuum variable temperature radiation source 3 with the receiving component 1, and record the radiance R of the vacuum variable temperature radiation source. b Receiver component output voltage V b .

[0042] Step S5: Drive the turntable 6 to rotate, and the receiving component 1 receives the vacuum variable temperature radiation source 3 through the cascaded thermal control coating sample, and records the radiance R of the vacuum variable temperature radiation source. s Receiver component output voltage V s .

[0043] Step S6: Using steps S4 and S5, and combining the two-point calibration equation, calculate the microwave loss value ΔR of the cascaded thermal control coating specimen.

[0044]

[0045] Since steps S4 and S5 respectively involve receiving the same vacuum temperature source through and without the cascaded thermal control coating sample, via R... b1 With R b R s1 With R s By comparison, nonlinear errors in the receiving component can be eliminated.

[0046] Step S7: Receiver 1 receives vacuum variable temperature radiation source 3 through a cascaded thermally controlled coating sample. The radiance of vacuum variable temperature radiation source 3 is controlled to R. b By using a precision temperature control device for thermal control coating, the temperature of the cascaded thermal control coating test pieces is controlled to T. OH T OM T OL Record the output voltage V of receiving component 1 respectively. OH V OM V OL The temperature inside the temperature control box 23 is controlled to T through precise temperature control. S The microwave radiance corresponding to the physical temperature of the thermal control coating specimen is R. OH R OM R OL Calculate the microwave loss value ΔR of three groups of cascaded thermal control coating specimens. H ΔR M and ΔR L .

[0047] ΔR i =(η2η1ρ 2 -1)R b +η2η1ρ(1-ρ)R Oi +η2(1-ρ)R Oi +η2(1-η1)ρR S +(1-η2)R S

[0048] In the above formula, i = H, M, L, ρ is the microwave reflectivity of the cascaded thermal control coating specimen. Since the two thermal control coating specimens have the same process parameters, their microwave reflectivity is the same. η1 is the edge interception rate of cascaded thermal control coating specimen 1, and η2 is the edge interception rate of cascaded thermal control coating specimen 2.

[0049] Step S8: Based on the microwave loss values ​​ΔR of the three sets of cascaded thermal control coating test pieces given in step S7. H ΔR M and ΔR L Calculate the emissivity of the cascaded thermal control coating specimen.

[0050]

[0051] The reflectivity ρ of the cascaded thermal control coating specimen can be obtained from the above formula, and the microwave emissivity is ε = 1 - ρ. η1 can be accurately obtained by the near-field testing system.

[0052] Step S9: Since the incident angle of the cascaded thermal control coating specimens is 45°, the microwave emissivity at any incident angle can be obtained based on the microwave emissivity ε calculated in step 8.

[0053]

[0054] During the test, the position control mechanism 6 drives the receiving component 1 to rotate.

[0055] The propagation process of receiving high-temperature vacuum radiation source 4 by receiving component 1 is shown below:

[0056] Vacuum high-temperature radiation source 4 → Parabolic reflector 12 → Receiver and feed horn 11;

[0057] The propagation process of receiving vacuum cryogenic radiation source 5 by receiving component 1 is shown below:

[0058] Vacuum cryogenic radiation source 5 → Parabolic reflector 12 → Receiver and feed horn 11;

[0059] The propagation process of receiving vacuum variable temperature radiation source 3 by receiving component 1 is shown below:

[0060] Vacuum variable temperature radiation source 3 → Parabolic reflector 12 → Receiver and feed horn 11;

[0061] The process by which the receiving component receives the propagation of vacuum variable temperature radiation source 3 through the cascaded thermally controlled coated specimen is shown below:

[0062] Vacuum variable temperature radiation source 3 → First-stage thermal control coating test piece 22 → Second-stage thermal control coating test piece 21 → Parabolic reflector 12 → Receiver and feed horn 11.

[0063] This invention utilizes the receiving component 1 to observe the same vacuum variable-temperature radiation source with and without passing through a cascaded thermally controlled coating specimen, thus eliminating the nonlinear error of the receiving component 1. A parabolic reflector 12 is used to form a plane wave that irradiates the cascaded thermally controlled coating specimen at a 45° incident angle, eliminating the influence of inconsistent incident angles caused by beam diffusion on the test results. Precise temperature control of the thermally controlled coating specimen is employed to obtain three sets of loss values ​​for the cascaded thermally controlled coating specimen at different temperatures. Through an error correction method, the emissivity of the cascaded thermally controlled coating specimen is accurately obtained. This test result can be used for microwave emissivity at any incident angle on the reflector surface, solving the engineering problem of inaccurately measuring the emissivity of large-aperture antennas in the terahertz band.

[0064] The microwave emissivity testing device and method for radiometer antennas provided by this invention can be widely used not only for emissivity testing of thermal control coating specimens for geostationary microwave radiometer antennas, but also for emissivity testing of various microwave radiometer antennas. It is not limited to single-band, single-polarization microwave emissivity testing, nor is it limited to thermal control coating testing of two cascaded specimens.
