Fig. 3 is a schematic structural diagram of an antenna performance testing apparatus according to another embodiment of the present invention. As shown in fig. 3, the antenna performance testing apparatus of this embodiment includes a first obtaining module 11, a second obtaining module 12, a third obtaining module 13, and an antenna performance testing module 14. The antenna performance testing module 14 includes: a signal analysis module 141 and an antenna performance test sub-module 142.
Specifically, the present embodiment utilizes the signal analysis module 141 to analyze the signal characteristics of the transmission signal and/or the signal characteristics of the reception signal, where the signal characteristics include: frequency, wavelength, power value. For example, the antenna performance testing device based on the virtual instrument technology has rich advanced signal processing controls in the LabVIEW, and the controls can process time-invariant signals and time-variant signals. For example, the LabVIEW has built-in advanced signal processing controls such as a filter control, a time domain analysis control, and a frequency domain analysis control, and the signal analysis module 141 is developed by combining a plurality of controls in this embodiment, and the signal analysis module 141 can transmit the signal characteristics of the signal and/or receive the signal characteristics of the signal, such as frequency, wavelength, power value, and amplitude.
Specifically, the antenna performance test sub-module 142 in this embodiment tests the antenna performance according to the signal characteristics, the distance between the receiving antenna 1 and the transmitting antenna 2, and the inclination angle of the receiving antenna 1. Optionally, the antenna performance testing sub-module 142 includes an antenna gain testing module and an antenna pattern drawing module.
The antenna gain testing module tests the antenna gain according to the signal characteristics and the distance between the receiving antenna 1 and the transmitting antenna 2. For example, the "two-phase same antenna test method" is a simple and fast antenna gain test method in the antenna gain test method, and the gain calculation algorithm of the "two-phase same antenna test method" is as follows:
GT+PT＝PR+2R-2λ-GR+p
wherein, PTIs the power of the transmitted signal; gTIs the gain of the transmit antenna 2; pRIs the power of the received signal; gRIs the gain of the receiving antenna 1; λ is the wavelength of the received signal; r is the distance between the transmitting antenna 2 and the receiving antenna 1; p is a correction value.
Specifically, the general procedure of the "two-phase same antenna test method" test is as follows: first, one standard antenna is prepared, and the standard antenna is an antenna having a known gain. Secondly, the standard antenna is used as a transmitting antenna 2, the antenna to be tested is used as a receiving antenna 1, the transmitting antenna 2 is connected with a signal source, and the signal source is used for providing signals for the transmitting antenna 2 to transmit. Then, measuring the distance between the transmitting antenna 2 and the receiving antenna 1, and testing the power of the transmitting signal of the transmitting antenna 2 and the power of the receiving signal of the receiving antenna 1; performing signal analysis on a received signal of the receiving antenna 1 to obtain a wavelength; finally, the gain of the receiving antenna 1 can be obtained by substituting the distance between the transmitting antenna 2 and the receiving antenna 1, the gain of the transmitting antenna 2, the power of the transmitted signal, the power of the received signal, the wavelength of the received signal, and an empirically known correction value into the above formula.
For further example, first, an antenna gain test module is designed on a front panel (i.e., a user interface) by using a "data input and display control" built in the LabVIEW, for example, a "distance" control between the transmitting antenna 2 and the receiving antenna 1, a "gain" control of the transmitting antenna 2, a "power of a transmitted signal" control, a "power of a received signal" control, a "wavelength of a received signal" control, and a "correction value" control are designed by using a "data input control" built in the LabVIEW; and the gain control of the receiving antenna 1 is designed by using a built-in data display control in the LabVIEW. And secondly, switching to a program block diagram of an antenna gain test module, and connecting the controls according to a gain calculation algorithm provided by the two same antenna test methods to generate a program block diagram matched with the two same antenna test methods. Further, the "distance between the transmitting antenna 2 and the receiving antenna 1" control may be manually or automatically input "the distance between the transmitting antenna 2 and the receiving antenna 1", and whether the "distance between the transmitting antenna 2 and the receiving antenna 1" is manually or automatically input depends on whether the adopted range finder is connected with the antenna testing device, if the selected range finder is not connected with the antenna testing device, the "distance between the transmitting antenna 2 and the receiving antenna 1" may only be manually input, and if the selected range finder is connected with the antenna testing device, the antenna performance testing device may obtain "the distance between the transmitting antenna 2 and the receiving antenna 1" and input the "distance between the transmitting antenna 2 and the receiving antenna 1" control. The "gain of the transmitting antenna 2" may be manually input using the "gain of the transmitting antenna 2" control. The "power of transmitted signal" control, the "power of received signal" control, and the "wavelength of received signal" control are respectively connected to the signal analysis module 141, so that the corresponding signal characteristics analyzed by the signal analysis module 141 are transmitted to the "power of transmitted signal" control, the "power of received signal" control, and the "wavelength of received signal" control. Finally, the antenna performance testing device is operated, and the tested gain of the receiving antenna 1 can be displayed through the gain of the receiving antenna 1 control.
Furthermore, the gain calculation algorithm is not limited to the exemplified "two-phase same antenna test method", but may be other algorithms, and a matched antenna gain test module is designed according to the characteristics of each algorithm, and meanwhile, an algorithm selection module may also be designed, and the corresponding antenna gain test module is started by the algorithm selection module to execute the antenna gain test work.
The antenna directional diagram drawing module is used for obtaining the incidence relation between the inclination angle of the receiving antenna 1 and the power value of the received signal, wherein each inclination angle is associated with one power value of the received signal; and drawing an antenna directional diagram according to the incidence relation.
The directional pattern of the antenna reflects the radiation characteristics of the antenna, and generally, the directional pattern of the antenna represents the distribution pattern of the power or the field intensity of electromagnetic waves radiated by the antenna in each direction. For example, in the present embodiment, the antenna to be measured is used as the receiving antenna 1, and the power values of the received signals at different tilt angles are obtained to map the antenna directional diagram. As shown in fig. 2, in the antenna performance testing system, a turntable is further disposed between the receiving antenna 1 and the tripod, and the receiving antenna 1 can be driven to rotate within a range of 360 ° by rotating the turntable, that is, the inclination angle of the receiving antenna 1 is changed. Furthermore, the turntable is provided with a dial, and a tester can manually rotate the turntable by means of the dial; or the turntable is an automatic turntable to rotate the turntable at a precise angle, and the power values of the received signals of the receiving antenna 1 are different when the turntable is rotated each time.
Taking an antenna performance testing apparatus based on a virtual instrument technology as an example, the antenna performance testing apparatus may test the power values of the received signals of the receiving antenna 1 at different tilt angles through the signal analysis module 141. Further, the antenna performance testing apparatus further includes: and a historical data management module. For example, the power values of the reception signals of the reception antennas 1 at different tilt angles are stored in the historical data management module. Further, the historical data management module may store the association relationship between the tilt angle of the receiving antenna 1 and the power value of the received signal. Specifically, if the turntable is a manual turntable, each time the turntable is manually rotated, a power value of a received signal is generated and stored in the historical data management module, an 'inclination angle' input control is designed, the input 'inclination angle' is stored in the historical data management module by designing a program diagram, and an association relationship between the inclination angle of the receiving antenna 1 and the power value of the received signal is formed in the historical data management module. If the rotary table is an automatic rotary table, the program block diagram is designed to store the 'inclination angle' and the associated 'power value of the received signal' into the historical data management module, and the historical data management module forms the association relationship between the inclination angle of the receiving antenna 1 and the power value of the received signal.
The user interface of the antenna performance testing device based on the virtual instrument technology also comprises an antenna directional diagram control, the incidence relation between the inclination angle of the receiving antenna 1 and the power value of a received signal in the historical data management module can be obtained through a design program diagram, the antenna directional diagram is drawn according to the incidence relation, and the drawn antenna directional diagram can be displayed on the user interface.
