Example

[0059] In view of the problem that the existing method for obtaining the boundary of electromagnetic pulse coordinated deployment of the RF system cannot realize the coordinated deployment design of the RF system with different electromagnetic pulse equipment at the same time, this embodiment 1 provides a coordinated deployment method of the RF system and the electromagnetic pulse equipment, which can overcome the problems that the RF system can only be coordinated with a single electromagnetic pulse equipment, the coordinated deployment design process is complicated, and the coordinated deployment design results are poorly quantifiable. It can solve the problem that the RF system cannot be coordinated with multiple electromagnetic pulse equipment at the same time in actual applications.

[0060] The coordinated deployment method of the radio frequency system and electromagnetic pulse equipment provided in this embodiment 1 can enable the radio frequency system equipment to complete the coordinated deployment design with multiple electromagnetic pulse equipment at the same time. That is to say, in the coordinated deployment method of the radio frequency system and electromagnetic pulse equipment provided in this embodiment 1, the radio frequency system equipment can complete the coordinated deployment design with electromagnetic pulse equipment 1, electromagnetic pulse equipment 2, electromagnetic pulse equipment 3... electromagnetic pulse equipment 1... electromagnetic pulse equipment N, wherein, The number of electromagnetic pulse devices is selected according to actual needs. Although the coordinated deployment method of the radio frequency system and the electromagnetic pulse device provided in this embodiment 1 can be applied to the coordinated deployment between multiple electromagnetic pulse devices in the radio frequency system, this embodiment 1 is particularly suitable for the case where the number of electromagnetic pulse devices is two or three.

[0061] Specifically, Figure 1 As shown, the coordinated deployment method of the radio frequency system and the electromagnetic pulse device provided in this embodiment 1 includes the following steps:

[0062] S1, binding electromagnetic pulse parameters for each electromagnetic pulse device.

[0063] In this embodiment 1, the revision of the electromagnetic pulse parameters in step S1 includes determining the operating wavelength of each electromagnetic pulse device, the main beam deflection angle of the electromagnetic pulse device i relative to the receiving antenna of the radio frequency system, and the radiation power density of the electromagnetic pulse device i where the receiving antenna of the radio frequency system is located, wherein: That is, when revising the electromagnetic pulse parameters, it includes the main beam deflection angle of electromagnetic pulse device 1 relative to the RF system receiving antenna, the main beam deflection angle of electromagnetic pulse device 2 relative to the RF system receiving antenna…the main beam deflection angle of electromagnetic pulse device N-1 relative to the RF system receiving antenna, the radiation power density of electromagnetic pulse device 1 where the RF system receiving antenna is located, the radiation power density of electromagnetic pulse device 2 where the RF system receiving antenna is located…the radiation power density of electromagnetic pulse device N-1 where the RF system receiving antenna is located.

[0064] For the sake of simplicity, when designing the coordinated deployment between the radio frequency system equipment, the electromagnetic pulse equipment 1 and the electromagnetic pulse equipment 2, the binding of the electromagnetic pulse parameters may include the following: the working wavelength of the electromagnetic pulse equipment 1, the working wavelength of the electromagnetic pulse equipment 2, the main beam deflection angle of the electromagnetic pulse equipment 1 relative to the radio frequency system receiving antenna, the radiation power density of the electromagnetic pulse equipment 1 where the radio frequency system receiving antenna is located, etc. For example, the electromagnetic pulse parameters may be bound as follows: the working wavelength of the electromagnetic pulse equipment 1 is 0.03m, the working wavelength of the electromagnetic pulse equipment 2 is 0.05m, the main beam deflection angle of the electromagnetic pulse equipment 1 relative to the radio frequency system receiving antenna is 30°, and the radiation power density of the electromagnetic pulse equipment 1 where the radio frequency system receiving antenna is located is 300W / m 2 .

[0065] S2, generating the directional pattern envelope data of the RF system receiving antenna according to the directional pattern data of the RF system receiving antenna in the working frequency band of each electromagnetic pulse device, so as to obtain the directional gain of the RF system receiving antenna when it deviates from the main beam angle of the RF system receiving antenna at the working wavelength of each electromagnetic pulse device.

[0066] Preferably, in order to improve the effectiveness of the subsequent calculation of the compatible working boundary results of the radio frequency system and each electromagnetic pulse device, in step S2, after determining the directional pattern data of the radio frequency system receiving antenna in each electromagnetic pulse device working frequency band, the directional pattern data is then calculated according to each Divide the directional pattern data into equal width data segments; and take the maximum value of the directional gain in each data segment and the angle value corresponding to the maximum value of the directional gain in the segment to form the directional pattern envelope data under the corresponding electromagnetic pulse device. After dividing the directional pattern data into equal segments, taking the maximum value of the directional gain in each segment and the corresponding angle value to form the directional pattern envelope can effectively remove the resonance points in the directional pattern data, thereby facilitating the effectiveness of the subsequent calculated compatible working boundary results of the radio frequency system and each electromagnetic pulse device.

[0067] Preferably, the directional pattern data may be a two-column multi-row array, wherein one column may be an angle value, and the other column may be a directional gain value corresponding to the angle. It should be understood that The value will affect the removal of resonance points in the pattern data and the applicability of the pattern envelope. When the value is small, the resonance point may not be effectively removed; When the value is large, the gain jump in the directional pattern data may be large. The preferred range is .

[0068] In step S2, in order to improve the accuracy of the subsequent calculation of the compatible working boundary results of the radio frequency system and each electromagnetic pulse device, in step S2, when determining the directional pattern data of the radio frequency system receiving antenna in the working frequency band of each electromagnetic pulse device, the angle of the radio frequency system receiving antenna is adjusted within 360° according to the following formula: Of course, The value will affect the accuracy of the final compatible working boundary calculation results. The smaller the value of is, the higher the accuracy of the calculation is, but the cost will also be higher. The preferred range is .

[0069] Preferably, considering economic cost, result accuracy and reliability, The value range is as well as The value range is When , the comprehensive benefit is the greatest. For example, the directional pattern data can be an array of 2 columns and 361 rows. The first column is the angle value of the change in the direction of the RF system receiving antenna, ranging from -180° to 180° and taking values ​​at equal intervals of 1°; the second column is the directional gain value of the corresponding angle. The directional pattern data can be divided into equal-width data segments every 5°. In each data segment, the maximum value of the directional gain in the segment and the angle value corresponding to the maximum value are taken to form an array of 2 columns and 73 rows.

[0070] S3, determining interference threshold data of each electromagnetic pulse device to the radio frequency system receiver, and generating an electromagnetic pulse interference threshold curve of the radio frequency system receiver according to the determined interference threshold data.

[0071] When determining the interference threshold data of each electromagnetic pulse device to the radio frequency system receiver, first determine the maximum interference threshold of each electromagnetic pulse device to the radio frequency system; then combine the N electromagnetic pulse devices in pairs, and in each combination, reduce the power of the maximum interference threshold of one of the electromagnetic pulse devices to the radio frequency system in stages, and test the interference threshold of another electromagnetic pulse device in the combination at each power value; then divide and combine the N electromagnetic pulse devices into N-1 and 1, and in each combination, reduce the power of the maximum interference threshold of the N-1 electromagnetic pulse device to the radio frequency system in stages, and test the interference threshold of another electromagnetic pulse device in the combination at each power value. That is, when the N electromagnetic pulse devices are divided into N-1 and 1, a total of Preferably, when the power of the N-1 electromagnetic pulse devices in each group to the maximum interference threshold of the radio frequency system is reduced in batches, the power of the N-1 electromagnetic pulse devices is reduced in the same manner each time.

[0072] like Figure 2 As shown, when the electromagnetic pulse interference threshold curve of the radio frequency system receiver is generated by the obtained interference threshold data, it can be obtained by performing spline interpolation on the interference threshold data, so as to make the generated electromagnetic pulse interference threshold curve of the radio frequency system receiver smoother.

[0073] For the sake of simplicity, when the coordinated deployment design is performed between the radio frequency system equipment, the electromagnetic pulse equipment 1 and the electromagnetic pulse equipment 2, and when determining the interference threshold data of each electromagnetic pulse equipment to the radio frequency system receiver,

[0074] First determine the interference threshold P of the electromagnetic pulse device 1 to the radio frequency system 1-MAX , the interference threshold P of the electromagnetic pulse device 2 to the radio frequency system 2-MAX ; Then the electromagnetic pulse device 1 is tested to have an injection power of P 1-MAX -3dB corresponding to the electromagnetic pulse device 2 interference threshold P 1-3dB ; The test shows that the injection power of electromagnetic pulse device 1 is P 1-MAX The corresponding electromagnetic pulse device 2 interference threshold P at -6dB 1-6dB ; The test shows that the injection power of electromagnetic pulse device 1 is P 1-MAX The corresponding electromagnetic pulse device 2 interference threshold P at -10dB 1-10dB ; The injection power of electromagnetic pulse device 1 is P 1-MAX / 2 corresponds to the electromagnetic pulse device 2 interference threshold P 1 / 2Of course, when determining the interference threshold data of the electromagnetic pulse device to the radio frequency system receiver, the interference threshold P of the electromagnetic pulse device 1 to the radio frequency system 1-MAX There is no limit on the number of times the power can be reduced, and it can be selected according to actual conditions.

[0075] Furthermore, in order to more accurately generate the electromagnetic pulse interference threshold curve of the RF system receiver through the obtained interference threshold data, in step S3, after the N electromagnetic pulse devices are combined in pairs, the power of each electromagnetic pulse device in each combination to the maximum interference threshold of the RF system is reduced in batches, and the interference threshold of another electromagnetic pulse device under the power value of each electromagnetic pulse device is obtained.

[0076] For the sake of simplicity, when the coordinated deployment design is performed between the RF system equipment, the electromagnetic pulse equipment 1 and the electromagnetic pulse equipment 2, and when determining the interference threshold data of each electromagnetic pulse equipment to the RF system receiver, the interference threshold P of the electromagnetic pulse equipment 1 to the RF system is included. 1-MAX , the interference threshold P of the electromagnetic pulse device 2 to the radio frequency system 2-MAX , the injection power of electromagnetic pulse device 1 is P 1-MAX -3dB corresponding to the electromagnetic pulse device 2 interference threshold P 1-3dB , the injection power of electromagnetic pulse device 1 is P 1-MAX The corresponding electromagnetic pulse device 2 interference threshold P at -6dB 1-6dB , the injection power of electromagnetic pulse device 1 is P 1-MAX The corresponding electromagnetic pulse device 2 interference threshold P at -10dB 1-10dB , the injection power of electromagnetic pulse device 1 is P 1-MAX / 2 corresponds to the electromagnetic pulse device 2 interference threshold P 1 / 2 ;as well as

[0077] When determining the interference threshold data of the electromagnetic pulse device to the radio frequency system receiver, it also includes the injection power of the electromagnetic pulse device 2 as P 2-MAX -3dB corresponding to the electromagnetic pulse device 1 interference threshold P 2-3dB , the injection power of electromagnetic pulse device 2 is P 2-MAX The corresponding electromagnetic pulse device 1 interference threshold P at -6dB 2-6dB , the injection power of electromagnetic pulse device 2 is P 2-MAX The corresponding electromagnetic pulse device 1 interference threshold P at -10dB 2-10dB , the injection power of electromagnetic pulse device 2 is P 2-MAX / 2 corresponds to the electromagnetic pulse device 1 interference threshold P 2 / 2Of course, the power value of the electromagnetic pulse device 2 for reducing the power of the maximum interference threshold of the radio frequency system in stages can be the same as or different from the power value of the electromagnetic pulse device 2 for reducing the power of the maximum interference threshold of the radio frequency system in stages. For example, it can be tested that the injection power of the electromagnetic pulse device 2 is P 2-MAX The corresponding electromagnetic pulse device 1 interference threshold P at -4dB 2-4dB .

[0078] More specifically, when the coordinated deployment design is performed between the RF system equipment, the electromagnetic pulse equipment 1 and the electromagnetic pulse equipment 2, and when the interference threshold data of each electromagnetic pulse equipment to the RF system receiver is determined, the interference threshold of the electromagnetic pulse equipment 1 to the RF system can be 50dBm, the interference threshold of the electromagnetic pulse equipment 2 to the RF system can be 40dBm, the interference threshold of the electromagnetic pulse equipment 2 corresponding to the injection power of the electromagnetic pulse equipment 1 is 47dBm, the interference threshold of the electromagnetic pulse equipment 2 corresponding to the injection power of the electromagnetic pulse equipment 1 is 2dBm, the interference threshold of the electromagnetic pulse equipment 2 corresponding to the injection power of the electromagnetic pulse equipment 1 is 44dBm, and the interference threshold of the electromagnetic pulse equipment 1 corresponding to the injection power of the electromagnetic pulse equipment 1 is 40dBm. m, the corresponding interference threshold of electromagnetic pulse device 2 is 13dBm, the corresponding interference threshold of electromagnetic pulse device 2 is 18dBm when the injection power of electromagnetic pulse device 1 is 25dBm, the corresponding interference threshold of electromagnetic pulse device 1 is 1dBm when the injection power of electromagnetic pulse device 2 is 37dBm, the corresponding interference threshold of electromagnetic pulse device 1 is 1dBm when the injection power of electromagnetic pulse device 2 is 34dBm, the corresponding interference threshold of electromagnetic pulse device 1 is 3dBm when the injection power of electromagnetic pulse device 2 is 30dBm, the corresponding interference threshold of electromagnetic pulse device 1 is 6dBm when the injection power of electromagnetic pulse device 2 is 20dBm, and the corresponding interference threshold of electromagnetic pulse device 1 is 12dBm when the injection power of electromagnetic pulse device 2 is 20dBm. The electromagnetic pulse interference threshold curve of the radio frequency system receiver is obtained by performing cubic spline interpolation on the interference threshold data of the electromagnetic pulse device to the radio frequency system receiver.

[0080] In step S4, in order to further ensure the reliability of the compatible working boundary calculation, when determining the compatible working boundary between the radio frequency system and each electromagnetic pulse device, a safety margin value K is also introduced in step S4 of this embodiment 1, and the compatible working boundary calculation model is,

[0087] It should be understood that the calculation results obtained by the compatible working boundary calculation model are is a range value, and the set of range values ​​is the working compatibility boundary of the coordinated deployment of radio frequency systems and electromagnetic pulse equipment.

[0088] To simplify the description, when the coordinated deployment design is performed between the radio frequency system equipment, the electromagnetic pulse equipment 1 and the electromagnetic pulse equipment 2, the coordinated deployment design model is:
