[0054] This application provides a detector antenna sensitivity measurement system that automates the sensitivity measurement of slanted-polarized millimeter-wave detector antennas, providing a more accurate sensitivity measurement of slanted-polarized millimeter-wave detector antennas compared to independent manual measurement.

[0055] Reference Figure 1 The sensitivity measurement system for the detector antenna is described in detail below:

[0056] The detector antenna sensitivity measurement system includes: a signal source 101, a millimeter-wave single-polarized standard horn antenna 102, an oscilloscope 103, a measurement dark box 104, and a control device 105.

[0057] The signal source 101 is electrically connected to the millimeter-wave single-polarized standard horn antenna 102 and is used to provide an input signal to the millimeter-wave single-polarized standard horn antenna 102.

[0058] A millimeter-wave single-polarized standard horn antenna 102 is used to output vertically polarized microwave signals or horizontally polarized microwave signals; wherein, the millimeter-wave single-polarized standard horn antenna 102 is opposite to the antenna surface of the detector antenna P to be measured; both the millimeter-wave single-polarized standard horn antenna 102 and the detector antenna P to be measured are set in the measurement dark box 104; the detector antenna P to be measured is an obliquely polarized millimeter-wave detector antenna.

[0059] The oscilloscope 103 is electrically connected to the detector antenna P under test and is used to measure the output amplitude of the detector antenna P under test under vertically polarized microwave signals or under horizontally polarized microwave signals.

[0060] The control device 105 is electrically connected to the oscilloscope 103 and is used to calculate the sensitivity of the detector antenna P under test based on the output amplitude of the detector antenna P under vertical polarization microwave signal and the output amplitude of the detector antenna P under horizontal polarization microwave signal.

[0061] The aforementioned detector antenna sensitivity measurement system uses control device 105 to acquire the output amplitude of the detector antenna P under vertical polarization microwave signal and the output amplitude of the detector antenna P under horizontal polarization microwave signal, and calculates the sensitivity of the detector antenna P. This achieves automation of the sensitivity measurement of the slanted polarization millimeter-wave detector antenna P, reduces the workload of manual measurement, improves measurement efficiency, and at the same time, automated measurement can reduce the error of manual measurement and better ensure the accuracy of measurement.

[0062] Specifically, the signal source 101 can also be connected to the control device 105. The control device 105 connects to the millimeter-wave signal source (signal source 101) via a USB-to-GPIB port and sets the signal frequency, signal power, and signal mode of the signal transmitter. The millimeter-wave signal source is connected to the millimeter-wave single-polarization standard horn antenna 102 via a millimeter-wave test cable and sends input signals to the millimeter-wave single-polarization standard horn antenna 102.

[0063] For example, refer to Figure 1 and Figure 2 The detector antenna sensitivity measurement system may further include: a first electric turntable 106 and a second electric turntable 107; both the first electric turntable 106 and the second electric turntable 107 are located inside the measurement dark box 104, the detector antenna P to be measured is located on the first electric turntable 106, and the first electric turntable 106 is located on the second electric turntable 107.

[0064] The first electric turntable 106 rotates, causing the azimuth angle of the detector antenna P to be measured to rotate.

[0065] When the second electric turntable 107 rotates, it drives the detector antenna P to be measured and the first electric turntable 106 to rotate, so that the elevation angle of the detector antenna P to be measured rotates.

[0066] Specifically, the first electric turntable 106 has a rotation range of 360°, and the second electric turntable 107 has a rotation range of 180°. That is, the second electric turntable 107 will not rotate the detector antenna P to be measured outside the radiation range of the millimeter-wave single-polarized standard horn antenna 102.

[0067] Specifically, such as Figure 3 As shown, the direction perpendicular to the antenna surface of the detector antenna P to be measured is the antenna normal phase, as... Figure 2As shown, the antenna normal of the detector antenna P to be measured points towards the millimeter-wave single-polarized standard horn antenna 102. The azimuth angle of the detector antenna P to be measured refers to ∠1 in the detector antenna P. The rotation of the first motorized turntable 106 causes a change in ∠1. The elevation angle of the detector antenna P to be measured refers to the angle ∠2 between the direction of the transmitted signal of the millimeter-wave single-polarized standard horn antenna 102 and the antenna surface of the detector antenna P to be measured. The rotation of the second motorized turntable 107 causes a change in ∠2. By setting the first motorized turntable 106 and the second motorized turntable 107, the sensitivity measurement of the detector antenna P to be measured can be achieved at different azimuth and elevation angles.

[0068] For example, control device 105 is connected to first electric turntable 106 and second electric turntable 107. The control device can also be used for:

[0069] The first electric turntable 106 and the second electric turntable 107 are controlled to rotate, so that the detector antenna P to be measured rotates to a preset angle. Based on the output amplitude of the detector antenna P under vertical polarization microwave signal and the output amplitude of the detector antenna P under horizontal polarization microwave signal when the detector antenna P is at the preset angle, the sensitivity of the detector antenna P when the detector antenna P is at the preset angle is calculated.

[0070] Specifically, the preset angles include azimuth and elevation angles. Calculating the sensitivity of the detector antenna P under test at different preset angles can provide a more comprehensive description of the product and facilitate its use by staff.

[0071] For example, the detector antenna sensitivity measurement system may also include: a mounting bracket 108;

[0072] The rotating surface of the second electric turntable 107 is parallel to the horizontal plane, and the fixed frame 108 is perpendicular to the horizontal plane. One end of the fixed frame 108 is fixedly connected to the second electric turntable 107, and the other end is fixedly connected to the first electric turntable 106. The rotating surface of the first electric turntable 106 is perpendicular to the horizontal plane.

[0073] Specifically, by setting up a fixed frame, the second electric turntable 107 is ensured to rotate, driving the detector antenna P to be measured and the first electric turntable 106 to rotate as they rotate. Figure 3 In the middle, the x-axis direction is parallel to the fixed frame 108.

[0074] For example, the control device 105 can be specifically used for:

[0075] Based on the first detector output step, the first loss, and the first output signal amplitude, the sensitivity of the detector antenna P to be measured in the vertical polarization direction is calculated; wherein, the first detector output step and the first loss are parameters of the detector antenna P to be measured under the vertically polarized microwave signal, and the first output signal amplitude is the output amplitude of the detector antenna P to be measured under the vertically polarized microwave signal.

[0076] Based on the second detector output step, the second loss, and the second output signal amplitude, the sensitivity of the detector antenna P to be measured in the horizontal polarization direction is calculated; wherein, the second detector output step and the second loss are the parameters of the detector antenna P to be measured under the horizontal polarization microwave signal, and the second output signal amplitude is the output amplitude of the detector antenna P to be measured under the horizontal polarization microwave signal.

[0077] The sensitivity of the detector antenna P to be measured is calculated based on the sensitivity of the detector antenna P in the vertical polarization direction and the sensitivity in the horizontal polarization direction.

[0078] For example, the formula for calculating the sensitivity of the detector antenna P under test in the vertical polarization direction can be:

[0079]

[0080] Where S1 represents the sensitivity of the detector antenna P to be measured in the vertical polarization direction, Δ1 represents the first detector output step, L1 represents the first loss, and A1 represents the amplitude of the first output signal.

[0081] The formula for calculating the sensitivity of the detector antenna P under test in the horizontal polarization direction can be:

[0082]

[0083] Where S2 represents the sensitivity of the detector antenna P to be measured in the horizontal polarization direction, Δ2 represents the second detector output step, L2 represents the second loss, and A2 represents the amplitude of the second output signal.

[0084] The formula for calculating the sensitivity of the detector antenna P to be measured can be:

[0085]

[0086] Where S represents the sensitivity of the detector antenna P to be measured.

[0087] Specifically, the first loss can include standard antenna gain (in dB), total cable attenuation (in dB), and measured spatial loss (in dB). Total cable attenuation refers to the total attenuation of the cable from signal source 101 to millimeter-wave single-polarized standard horn antenna 102. Measured spatial loss refers to the spatial loss of the microwave signal transmitted by the millimeter-wave single-polarized standard horn antenna 102 as it travels to the detector antenna P under test. The first and second losses include the same components; they are simply different ways of describing the sum of the same losses under different conditions.

[0088] Specifically, the amplitudes of the first and second output signals of the first and second detector output steps can both be obtained by sampling with an oscilloscope.

[0089] Specifically, the formula for calculating sensitivity is defined, the calculation process is simple, and the efficiency of the output results is guaranteed, enabling accurate and rapid automated measurement of the sensitivity of slanted polarized millimeter-wave detector antennas.

[0090] For example, the detector antenna sensitivity measurement system may further include: a power supply 109; the power supply 109 is connected to the detector antenna P to be measured and is used to supply power to the detector antenna P. The power supply 109 may be a DC regulated power supply.

[0091] Figure 4 This is a schematic flowchart of a detector antenna sensitivity measurement method provided in an embodiment of this application. The execution terminal of this method can be the control device 105 described above. Figure 4 The method for measuring the sensitivity of this detector antenna is described in detail below:

[0092] Step 201: When the millimeter-wave single-polarized standard horn antenna 102 is placed vertically for operation, the first detector output step, the first loss, and the first output amplitude of the detector antenna P to be measured are obtained.

[0093] Step 202: When the millimeter-wave single-polarized standard horn antenna 102 is placed horizontally for operation, the second detector output step, the second loss, and the second output amplitude of the detector antenna P to be measured are obtained.

[0094] Step 203: Calculate the sensitivity of the detector antenna P to be measured in the vertical polarization direction based on the first detector output step, the first loss, and the first output amplitude; calculate the sensitivity of the detector antenna P to be measured in the horizontal polarization direction based on the second detector output step, the second loss, and the second output amplitude.

[0095] Step 204: Calculate the sensitivity of the detector antenna P to be measured based on its sensitivity in the vertical polarization direction and its sensitivity in the horizontal polarization direction.

[0096] Specifically, in order to perform a more comprehensive sensitivity measurement of the detector antenna, it is also necessary to: control the first electric turntable 106 and the second electric turntable 107 to rotate, so that the detector antenna P to be measured is rotated to a preset angle, and calculate the sensitivity of the detector antenna P when it is located at the preset angle based on the output amplitude of the detector antenna P under vertically polarized microwave signal and the output amplitude of the detector antenna P under horizontally polarized microwave signal when it is located at the preset angle.

[0097] The above-mentioned method for measuring the sensitivity of a detector antenna will be illustrated below with a specific implementation example.

[0098] Reference Figure 2 The method includes:

[0099] Step 1: Position the millimeter-wave single-polarization standard horn 102 as horizontally polarized.

[0100] Step 2: Use the control device 105 to control the first electric turntable 106 to rotate the azimuth angle of the detector antenna P to be measured, and read the output amplitude of the horizontally polarized microwave signal measured by the oscilloscope 103 through the network port.

[0101] Step 3: Position the millimeter-wave single-polarization standard horn 102 as vertically polarized.

[0102] Step 4: Read the output amplitude of the vertically polarized microwave signal measured by oscilloscope 103 via the network port.

[0103] Step 5: Use the control device 105 to control the second electric turntable 107 to rotate the elevation angle of the detector antenna P to be measured.

[0104] Step 6: Determine if the test is complete.

[0105] If step 7 is completed, the test is interrupted; if not completed, steps 1 through 5 are repeated.

[0106] Step 8: Based on the output amplitude of the horizontally polarized microwave signal and the output amplitude of the vertically polarized microwave signal at the preset angle, calculate the sensitivity of the detector antenna P to be measured in the vertical polarization direction and the sensitivity of the detector antenna P to be measured in the horizontal polarization direction, and then calculate the sensitivity of the detector antenna to be measured at the preset angle.

[0107] Step 9: Calculate the sensitivity of the detector antenna under different preset angles.
