[0001] The present application relates to the field of software radio communication, especially the wireless communication, navigation and identification device of civil aircraft, and is a comprehensive radio frequency transceiver system for time-sharing multiplexing of spectrum resources, which realizes radiation control and receiving locking method of airborne radio frequency transceiver system in the same / adjacent frequency band. BACKGROUND

[0002] Radio frequency management is one of the key technologies of airborne comprehensive radio frequency transceiver system. The comprehensive scheme of airborne comprehensive radio frequency transceiver system mainly includes aperture synthesis and radio frequency synthesis. Aperture synthesis refers to that two airborne devices working in the same / adjacent frequency band share a set of antennas for transmission and reception, and aperture resource multiplexing can reduce the number of installed antennas, save aircraft skin resources, optimize aircraft antenna layout and improve aircraft electromagnetic compatibility performance; radio frequency synthesis refers to that two airborne devices working in the same / adjacent frequency band multiplex the receiving channel and power amplifier circuit for radio frequency transmission and reception, and radio frequency channel multiplexing can reduce the number of installed devices, universalize radio frequency transmission and reception resources, optimize system reconstruction and improve the reliability of airborne devices.

[0003] The essence of comprehensive airborne comprehensive radio frequency transceiver system is the universalization of aperture and radio frequency channel and its time-sharing multiplexing to multiple different functions. Therefore, when different functions multiplex the same hardware transceiver link, the radiation management and locking mechanism of its function become the key to the success of radio frequency synthesis. SUMMARY

[0004] The purpose of the present application is to provide a radiation control and receiving locking method of civil airborne comprehensive radio frequency transceiver system, which realizes the radio frequency management of the same / adjacent frequency band.

[0005] The purpose of the present application is achieved by the following technical solutions:

[0006] A radiation control and receiving locking method of civil airborne comprehensive radio frequency transceiver system, comprising the following contents:

[0007] Link state parameter definition:

[0008] (1) For each waveform function signal processing module, three state parameters need to be defined:

[0009] 1) Transmit locking output: when the signal processing module outputs a signal, the transmit locking output should be valid;

[0010] 2) Receive locking input: when the receive locking input is valid, the signal processing module is prohibited to process the received signal;

[0011] 3) Transmit locking input: when the transmit locking input is valid, the signal processing module is prohibited to output a signal;

[0012] (2) For the radio frequency transmitting channel, two state variables need to be defined:

[0013] 1) Transmit switch input: when the transmit switch input is valid, the radio frequency transmitting channel enables each stage of the power amplifier, and has the condition of radiating pulse signals;

[0014] 2) Power amplifier mode n input: n is the number of the signal processing module, when the power amplifier mode input of the signal processing module n is valid and the power amplifier mode input of the remaining signal processing modules is invalid, the radio frequency transmitting channel receives and processes the output signal of the signal processing module n;

[0015] (3) For the radio frequency receiving channel, one state variable needs to be defined

[0016] 1) Receive lock input: when the receive lock input is valid, the radio frequency receiving channel prohibits processing the received signal;

[0017] State variable association logic:

[0018] (1) When the transmit lock output of the current signal processing module is valid, the receive lock input and the transmit lock input of the remaining signal processing modules are simultaneously valid;

[0019] (2) When the transmit lock output of the current signal processing module is valid, the transmit switch input and the corresponding power amplifier mode n input of the radio frequency transmitting channel are simultaneously valid;

[0020] (3) When the transmit lock output of the current signal processing module is valid, the receive lock input state variable of the radio frequency transmitting channel is simultaneously valid.

[0021] Further, the signal processing module also needs to define one state variable:

[0022] Transmit switch: when the signal processing module outputs a signal, the transmit switch is valid;

[0023] When any of the transmit switches of the signal processing modules is valid, the transmit switch input of the radio frequency transmitting channel is valid, enabling the radio frequency transmitting path; when the transmit switches of the signal processing modules are all invalid, the transmit switch input of the radio frequency transmitting channel is invalid, disabling the radio frequency transmitting path.

[0024] Further, when the transmit switch of the current signal processing module is valid and the transmit switches of the remaining signal processing modules are invalid, the power amplifier mode n input corresponding to the current signal processing module is valid and the power amplifier mode n input corresponding to the remaining signal processing modules is invalid, so that the power amplifier module performs power amplification according to the mode of the current signal processing module;

[0025] When the transmit switches of all signal processing modules are invalid, the power amplifier module does not work;

[0026] When the transmitting switch of each signal processing module is valid, the power module does not work.

[0027] Further, the radiation control and receiving lock method of the civil airborne integrated radio frequency transceiver system further comprises a radiation control mechanism based on transmission competition:

[0028] If the transmission lock output of a signal processing module is valid, wait for a state parameter flip time slot Δt, and then execute the validity judgment of the transmission lock input state parameter, if the transmission lock output state parameter of other signal processing modules is valid within the state flip time slot Δt, a "transmission competition" is generated, and the transmission behavior of the signal processing module is terminated, and the transmission lock output is invalid.

[0029] Further, the radiation control and receiving lock method of the civil airborne integrated radio frequency transceiver system further comprises a state parameter flip time slot Δt determination and state parameter association scheme selection method:

[0030] ① According to the performance index requirements of the civil airborne integrated radio frequency transceiver system, the state flip time is determined;

[0031] ② Select a suitable state parameter transmission interface to meet the time slot requirement shown in ①.

[0032] Preferably, a differential discrete quantity is selected for state parameter transmission, and FPGA is used for state parameter management and logical operation.

[0033] The beneficial effects of the present application are:

[0034] The present application proposes an integrated radio frequency management method for hardware resource multiplexing of the navigation and identification functions of the integrated radio frequency transceiver system based on time-sharing multiplexing of spectrum resources, which has low time delay, high resource utilization rate, high reliability, effective radiation control and receiving lock, and meets the design expectation.

[0035] The receiving lock idea based on decentralized state parameter association solves the mutual interference problem of communication, navigation and identification functions working in the same frequency or similar frequency bands, realizes the time-sharing cooperative work of various functions of the integrated system, and has high reliability.

[0036] The radiation control idea based on transmission competition and later priority solves the potential conflict of the radiation control of the receiving-transmitting and transmitting-receiving systems, and has high safety. DETAILED DESCRIPTION

[0047] The application will be further described below in conjunction with the accompanying drawings and embodiments.

[0048] Referring to Figure 1 as shown, a typical civil airborne integrated radio transceiver system such as Figure 1 as shown, contains signal processing modules with various waveform functions, radio transmission channels, radio receiving channels, integrated apertures, and combiners, power dividers, circulators, etc.

[0049] The signal processing modules mainly have the functions of receiving, filtering, down-converting, sampling, and data processing of intermediate frequency signals; and have the functions of data processing (encoding), DA conversion, up-conversion, amplification, filtering, etc. of intermediate frequency transmission signals.

[0050] The radio transmission channels mainly have the functions of power amplification, filtering, etc.

[0051] The radio receiving channels mainly have the functions of power amplification, filtering, etc.

[0052] The integrated apertures mainly have the function of electromagnetic signal radiation.

[0053] Among them, the signal processing modules are cross-linked to each other to transmit state parameters; the power amplifier modules, the radio receiving channels, and each signal processing module are cross-linked respectively to transmit state parameters.

[0054] This embodiment takes an airborne long wave radio transceiver system as an example for illustration, referring toFigure 2 As shown in the figure, the signal processing module includes an ATC / ADS-B OUT function signal processing module and a DME function signal processing module, and the performance indicators of the ATC / ADS-B OUT function and the DME function are shown in Table 1:

[0055] Table 1 ATC / ADS-B OUT, DME, TCAS function indicators

[0056] ATC / ADS-B OUT DME Transmit frequency 1090 MHz 1025 MHz ~ 1150 MHz Receive frequency 1030 MHz 960 MHz ~ 1215 MHz Transmit power ≥ 54 dBm ≥250W Receive sensitivity -74 dBm -10 ~ -83 dBm

[0057] As can be seen from Table 1, the ATC / ADS-B OUT function signal processing module and the DME function signal processing module both work in the long wave band, and the ATC / ADS-B OUT function signal processing module and the DME function signal processing module both use omnidirectional antennas for signal transmission and reception, thereby determining that the ATC / ADS-B OUT function signal processing module and the DME function signal processing module can share the same set of transceiver links, and have integrated design conditions.

[0058] The radiation control and reception locking method of the civil airborne integrated radio frequency transceiver system shown in the embodiment includes the following contents:

[0059] 1. Link state parameter definition:

[0060] (1) For each waveform function signal processing module, 3 state parameters need to be defined:

[0061] 1) Transmit locking output: When the signal processing module outputs a signal, the transmit locking output should be set to be valid;

[0062] 2) Receive locking input: When the receive locking input is set to be valid, the signal processing module is prohibited from processing the received signal;

[0063] 3) Transmit locking input: When the transmit locking input is set to be valid, the signal processing module is prohibited from outputting a signal.

[0064] (2) For the radio frequency transmission channel, 2 state parameters need to be defined:

[0065] 1) Transmit switch input: When the transmit switch input is set to be valid, the radio frequency transmission channel enables the power amplifier at each stage, and has the condition of radiating a pulse signal.

[0066] 2) Power amplifier mode n input: n is the number of the signal processing module, when the power amplifier mode input of the signal processing module n is set to be valid and the power amplifier mode input of the remaining signal processing modules is set to be invalid, the radio frequency transmission channel receives and processes the output signal of the signal processing module n.

[0067] (3) For the radio frequency reception channel, 1 state parameter needs to be defined

[0068] 1) Receive Latch In: When the receive latch in is asserted, the RF receive channel is disabled from processing the signals it receives.

[0069] In the example of an airborne long wave radio transceiver system, the ATC / ADS-B OUT function signal processing module state variable definitions are:

[0070] ① ATC Transmit Latch Out: When the ATC / ADS-B OUT function signal processing module outputs a signal, the transmit latch out should be asserted;

[0071] ② ATC Receive Latch In: When the receive latch in is asserted, the ATC / ADS-B OUT function signal processing module is disabled from processing the signals it receives;

[0072] ③ ATC Transmit Latch In: When the transmit latch in is asserted, the ATC / ADS-B OUT function signal processing module is disabled from outputting a signal;

[0073] ④ ATC Transmit Switch: When the ATC / ADS-B OUT function signal processing module outputs a signal, the ATC transmit switch should be asserted;

[0074] ⑤ ATC Up / Down Antenna Select: When the ATC / ADS-B OUT function signal processing module outputs a signal, the ATC up / down antenna select should be asserted;

[0075] (2) DME function signal processing module state variable definitions:

[0076] ① DME Transmit Latch Out: When the DME function signal processing module outputs a signal, the transmit latch out should be asserted;

[0077] ② DME Receive Latch In: When the receive latch in is asserted, the DME function signal processing module is disabled from processing the signals it receives;

[0078] ③ DME Transmit Latch In: When the transmit latch in is asserted, the DME function signal processing module is disabled from outputting a signal;

[0079] ④ DME Transmit Switch: When the DME function signal processing module outputs a signal, the DME transmit switch should be asserted;

[0080] ⑤ DME Up / Down Antenna Select: When the DME function signal processing module outputs a signal, the DME up / down antenna select should be asserted;

[0081] ⑥ DME Transmit Trigger: When the DME function signal processing module outputs a signal, the DME transmit trigger should be asserted;

[0082] (3) L-band interface unit state variable definition:

[0083] ① Up-down antenna selection: ATC / ADS-B OUT function signal processing module, DME function signal processing module to avoid the antenna pattern distortion caused by the body shielding, ensure the performance of each direction in space, set up the up-down antenna for the full coverage of the spatial pattern. The up-down antenna selection realizes the selection of the radiating antenna for RF signal transmission;

[0084] ② Transmit switch input: ATC / ADS-B OUT function signal processing module, DME function signal processing module share 1 power amplifier circuit, and only in the waveform pulse transmission power amplifier circuit into effect, the transmission switch realizes the enable of the power amplifier circuit in the transmission link.

[0085] ③ Transmit trigger: ATC / ADS-B OUT function signal processing module, DME function signal processing module modulation mode is different, the transmission trigger realizes the modulation of DME waveform function double clock pulse;

[0086] ④ Power amplifier mode selection: ATC / ADS-B OUT function signal processing module, DME function signal processing module modulation mode is different, the power amplifier mode selection realizes the power amplifier circuit working in the working mode corresponding to a waveform function when transmitting a waveform function;

[0087] ⑤ Receive lock input: ATC / ADS-B OUT function signal processing module, DME function signal processing module transmission frequency and receiving frequency overlap, when the receive lock input is valid, the L-band antenna interface unit stops receiving RF signals.

[0088] 2. Decentralized state variable association logic:

[0089] (1) The transmission lockout output state variable of the signal processing module is associated with the receive lock input and the transmission lock input of the remaining signal processing modules.

[0090] When the transmission lockout output of the signal processing module is valid, the receive lock input and the transmission lock input of the remaining signal processing modules are simultaneously set to valid.

[0091] (2) The transmission lockout output state variable of the signal processing module is associated with the transmission switch input state variable of the RF transmission channel and the power amplifier mode input state variable of the corresponding function of the RF transmission channel.

[0092] When the transmission lockout output of the signal processing module is valid, the transmission switch input and the power amplifier mode n input of the corresponding function of the RF transmission channel are simultaneously set to valid.

[0093] (3) The transmit latch output state parameter of this signal processing module is related to the receive latch input state parameter of the radio frequency receiving channel.

[0094] When the transmit latch output of this signal processing module is valid, the receive latch input status parameter of the RF transmit channel is simultaneously set to valid.

[0095] In an example of an airborne longwave radio frequency transceiver system described in this embodiment:

[0096] (1) Transmitter switch state logic association:

[0097] like Figure 3 As shown, the ATC / ADS-B OUT function signal processing module and the DME function signal processing module output discrete values ​​for "ATC transmit switch" and "DME transmit switch" respectively to the main control interface module. The main control module performs an AND operation. When either "ATC transmit switch" or "DME transmit switch" is valid, the main control module's "transmit switch input" is valid, enabling the L antenna interface unit's transmit path. When both "ATC transmit switch" and "DME transmit switch" are invalid, the main control module's "transmit switch input" is invalid, closing the L antenna interface unit's transmit path. The transmit latching output state parameter of this signal processing module is associated with the receive latching input and transmit latching input state parameters of other signal processing modules.

[0098] (2) Logical association of the launch trigger state:

[0099] like Figure 4 As shown, the DME function signal processing module outputs the discrete value of "DME transmit trigger" to the main control interface module. When "DME transmit trigger" is valid, the main control module's "transmit trigger" is valid, enabling the DME waveform modulation function; when "DME transmit trigger" is invalid, the main control module's "transmit trigger" is invalid, making the DME waveform modulation function of the L antenna interface unit invalid.

[0100] (3) Logical association of transmit latching state:

[0101] like Figure 5 As shown, the ATC / ADS-B OUT function signal processing module outputs the discrete value of "ATC transmit latch-up output" to the main control interface module. When the ATC / ADS-B OUT function signal processing module transmits an RF signal, "ATC transmit latch-up output" is valid, and the "DME transmit latch-up input" of the main control module is set to valid. At this time, ATC occupies the transmit path resources until the waveform RF signal transmission ends, at which point "ATC transmit latch-up output" becomes invalid, and the transmit link resources are released.

[0102] The DME function signal processing module outputs a "DME transmission lockout output" discrete quantity to the main control interface module. When the DME waveform function transmits a radio frequency signal, the "DME transmission lockout output" is valid, the main control module "ATC transmission lockout input" is valid, at this time the DME occupies the transmission path resource, until the DME waveform radio frequency signal transmission ends, the "DME transmission lockout output" is invalid, and the transmission link resource is released.

[0103] (4) Power amplifier mode selection state logic association:

[0104] As shown in Figure 6 , the ATC / ADS-B OUT function signal processing module and the DME function signal processing module respectively output an "ATC transmission switch" discrete quantity and a "DME transmission switch" discrete quantity to the main control interface module. When the "ATC transmission switch" is valid and the "DME transmission switch" is invalid, the main control module "power amplifier mode 1 input" is valid and the "power amplifier mode 2 input" is invalid, so that the L antenna interface unit transmission path power amplifier circuit amplifies the ATC waveform radio frequency signal.

[0105] When the "ATC transmission switch" is invalid and the "DME transmission switch" is valid, the main control module "power amplifier mode 1 input" is invalid and the "power amplifier mode 2 input" is valid, so that the L antenna interface unit transmission path power amplifier circuit modulates and amplifies the DME waveform radio frequency signal.

[0106] When the "ATC transmission switch" and the "DME transmission switch" are both invalid, the main control module "power amplifier mode 1 input" and "power amplifier mode 2 input" are both invalid, and the L antenna interface unit transmission path power amplifier circuit does not work.

[0107] When the "ATC transmission switch" and the "DME transmission switch" are both valid (abnormal situation), the main control module "power amplifier mode 1 input" and "power amplifier mode 2 input" are both valid, and the L antenna interface unit does not work in this state. Transmission path power amplifier circuit.

[0108] (5) Signal processing module acceptance lockout input state logic association:

[0109] As shown in Figure 7 , the ATC / ADS-B OUT function signal processing module and the DME function signal processing module respectively give "ATC transmission lockout output" discrete quantity and "DME transmission lockout output" discrete quantity:

[0110] When the "ATC transmission lockout output" is valid, the main control module "DME reception lockout output" is valid, and the DME waveform function reception is locked out.

[0111] When the "DME transmit lockout output" is valid, the master module "ATC receive lockout output" is valid, and the ATC waveform function receives is locked out.

[0112] (6) L antenna interface unit receives lockout state logic association

[0113] As shown in the figure, the ATC / ADS-B OUT function signal processing module, DME function signal processing module respectively give "ATC transmit lockout output" discrete quantity, "DME transmit lockout output" discrete quantity: Figure 8

[0114] When either "ATC transmit lockout output", "DME transmit lockout output" is valid, the master module does "or" logic, the master module "receive lockout input" is valid, and the L antenna interface unit receives is locked out.

[0115] 3. Radiation control mechanism based on transmission competition:

[0116] From the state variables and state variable association logic, it can be deduced that the shortest time interval of the radiation control and receive lockout method of the civil airborne integrated long wave radio transceiver system is the time of state variable execution state flip. In the state flip time slot (defined as Δt), each state variable of the system is in an uncontrollable state. Therefore, the invention provides a radiation control idea of transmission competition and later priority.

[0117] As shown in the figure, each signal processing module is in a transmission competition relationship. If the transmit lockout output of a certain signal processing module is valid, it should wait for a state variable flip time slot (Δt) and then execute the transmit lockout input state variable validity judgment of itself. When other signal processing modules place the transmit lockout output state variable valid within the state flip time slot Δt, "transmission competition" is generated, and the signal processing module terminates its own transmission behavior, and the transmit lockout output is invalid. Figure 9 In the example of the certain airborne long wave radio transceiver system in this embodiment, the state variable association timing of the example system is as shown in the figure:

[0118] Figure 10 When the ATC / ADS-B OUT function radiates a signal:

[0119] First, judge whether the ATC transmit lockout input is valid. If not, set the ATC transmit lockout output valid.

[0120] Second, wait for 200ns, and judge again whether the ATC transmit lockout input is valid. If valid, terminate transmission; if not, execute ATC signal transmission.

[0121] Second, wait for 200ns, and judge again whether the ATC transmit lockout input is valid. If valid, terminate transmission; if not, execute ATC signal transmission.

[0122] ​​Third step, ATC signal radiation is completed, the ATC transmission lockout output is invalid, and the radiation is ended.

[0123] The same is true when the DME function signal processing module radiates signals.

[0124] 4. Determination of state parameter flip time slot (Δt) and state parameter association scheme selection method:

[0125] ① According to the performance index requirements of civil airborne integrated radio frequency transceiver system, the state flip time should be no more than:

[0126] For the receive interrogation-response system: 1 / 2 (the end time of receiving - the start time of initiating);

[0127] For the probe-receive echo system: 1 / 2 (the end time of receiving - the start time of transmitting);

[0128] In addition, in order to improve the reliability of the system, a certain time slot redundancy is usually used, such as when the time slot between receiving and transmitting in the radio frequency transceiver system is 5us, the longest state flip time is theoretically 2.5us, and the state flip time is recommended to be no more than 250ns in engineering implementation.

[0129] ② The state parameter flip time of the state parameter flip time slot (Δt) depends on the reading, analysis speed, transmission medium, etc. of the state parameter. A suitable state parameter transmission interface (port, cable, transmission mechanism) should be selected to meet the time slot requirements shown in ①.

[0130] Δt>>t (parameter sampling) + t (parameter analysis) + t (logic operation) + t (transmission delay)

[0131] In this embodiment example of a certain airborne long wave radio frequency transceiver system:

[0132] (1) Selection of state parameter flip time slot (Δt)

[0133] According to the performance index requirements of long wave band airborne equipment, the state flip time should be no more than:

[0134] For ATC / ADS-B OUT function: 1.5us±0.25us;

[0135] For DME function: 3us±0.5us;

[0136] This example system uses 10 times time slot redundancy, and the state flip time is no more than 150ns.

[0137] (2) Selection of state parameter association scheme

[0138] The state variable flip time slot (Δt) of the state variable depends on the reading, analysis speed, transmission medium, etc. of the state variable. In the example system, the differential discrete quantity is selected for state variable transmission, and the FPGA is used for state variable management and logical operation, which can satisfy that the state variable flip time is not greater than 50 ns.

[0139] Δt >> t (parameter sampling) + t (parameter analysis) + t (logical operation) + t (transmission delay) = 50 ns

[0140] It can be understood that, for those skilled in the art, equivalent replacements or changes can be made according to the technical solutions and inventive concepts of the present application, and all such changes or replacements shall fall within the protection scope of the appended claims of the present application.
