Description

Technical Field

[0001] The present invention relates to the field of multifunctional radio frequency integrated processing, and in particular to a frequency fully arranged agile photonics synaesthesia integrated device and a working method thereof. Background Art

[0002] With the continuous development and research of 5G and 6G, more and more technologies have emerged, bringing people unprecedented convenience and experience. In the civilian field, these technologies include vehicle networking based on 5G high-frequency positioning, indoor positioning and activity recognition based on WiFi, and drone synaesthesia integration. In the military field, these technologies mainly include radar-assisted low probability of intercept communication and passive radar. Compared with traditional civilian technologies, military applications focus more on the security and reliability of information. These applications undoubtedly put forward higher requirements for communication and perception functions: larger communication capacity, higher resolution perception images, more stable signal transmission, etc.

[0003] The emergence of synaesthesia integrated system and microwave photonic technology provides a feasible method to solve these problems. The advantage of synaesthesia integrated system is that it highly integrates dual functions, shares time domain, frequency domain, spatial domain and hardware resources, and effectively utilizes congested spectrum and hardware resources. The two functions can also enhance and assist each other, improving the performance of the integrated system. It is one of the important candidate solutions for future application fields; and microwave photonic technology has the advantages of anti-electromagnetic interference and large bandwidth, and it is easy to realize high-resolution radar.

[0004] At present, microwave photon synaesthesia integrated systems can be roughly divided into two categories: one is a system where perception and communication coexist, and the perception and communication functions share the system's hardware resources, spectrum resources or time resources through different multiplexing methods (time division multiplexing, frequency division multiplexing) to achieve the purpose of realizing both functions; the other is a dual-function synaesthesia integrated system, which uses a reasonable waveform design (for example, orthogonal frequency division multiplexing modulation (OFDM) waveform) to enable the signal to complete both the communication function and the radar detection function. However, these solutions cannot be applied in complex electromagnetic environments because their signals can be easily intercepted and cracked by the enemy. Summary of the invention

[0005] The present invention aims to provide a frequency-fully-arranged agile photonics synaesthesia integrated device and a working method thereof, so as to solve the problem that the existing method cannot be applied in a complex electromagnetic environment because its signal can be easily intercepted and cracked by the enemy.

[0006] The present invention provides a frequency-fully-arranged agile photonics synaesthesia integrated device, comprising a photonics agile frequency-synaesthesia integrated signal generating module, a dual-agile radar detection module and a large-information communication receiving module;

[0007] The photonics agile frequency conversion and interaceptive integrated signal generation module comprises a dual-wavelength laser, a dual-band agile integrated waveform generation module, a dual parallel light modulator, an optical filter, an optical coupler, a photodetector, a power amplifier and a transmitting antenna; the dual-band agile integrated waveform generation module is connected to the dual parallel light modulator; the output end 1 of the dual-wavelength laser is connected to the input end 1 of the optical coupler via the dual parallel light modulator and the optical filter in sequence, and the output end 2 of the dual-wavelength laser is connected to the input end 2 of the optical coupler; the output end of the optical coupler is connected to the photodetector, the power amplifier and the transmitting antenna in sequence;

[0008] The dual-agile radar detection module includes a receiving antenna 1, a low noise amplifier, an optical phase modulator, an optical power divider, a dual-channel photon radar de-skewing module and a digital signal processing module connected in sequence; the optical phase modulator is also connected to the output end of the optical coupler;

[0009] The large amount of information communication receiving module includes a receiving antenna 2 and an incoherent communication receiving module which are connected in sequence.

[0010] Furthermore, the dual-band agile integrated waveform generating module includes two multipliers, through which completely identical linear frequency modulation signals are divided into two paths, which are respectively multiplied with the N1-order frequency full-arrangement agile frequency modulation signal and the N2-order frequency full-arrangement agile frequency modulation signal to complete the up-conversion operation and obtain the agile band 1 linear frequency modulation signal and the agile band 2 linear frequency modulation signal with different initial frequencies.

[0011] Further, the N1-order frequency full-permutation agile frequency signal and the N2-order frequency full-permutation agile frequency signal are generated as follows:

[0012] Assuming that the effective length of the signal is N, obtain a random number k, and obtain the kth combination of the N-order full permutation through the Lehmer code. First, initialize, set x = k-1, y = 0, i = 1, and then judge the termination condition. When x is not equal to 1, assign the quotient of x divided by (N-1)! to x, y is equal to the remainder, i = i + 1, and enter the termination condition again for judgment until the condition is met. At this time, the corresponding Lehmer code sequence is deduced through the previous values ​​of x and N, and then the kth combination sequence is obtained. After multiplying by the same initial frequency, the frequency-agile signal is obtained.

[0013] Furthermore, the dual-wavelength laser consists of two lasers.

[0014] Furthermore, the dual-channel photon radar de-slant module is composed of an optical filter, a photodetector and an electrical filter.

[0015] Furthermore, the working method of the frequency-fully-arranged agile photonics synaesthesia integrated device comprises:

[0016] The dual-wavelength laser generates two optical carrier signals, one of which is input into a dual parallel optical modulator, and the other is input into an optical coupler; the dual-band agile integrated waveform generation module generates two agile band linear frequency modulation signals and inputs them into the dual parallel optical modulator; the dual parallel optical modulator modulates the two agile band linear frequency modulation signals on one optical carrier signal in a carrier suppressed double sideband manner, and then selects the two agile band linear frequency modulation signals of the upper sideband through an optical filter, and couples them with the other optical carrier signal; the coupled optical signal is divided into two parts, one part of which is input into the optical phase modulator of the dual agile radar detection module as a reference optical signal for radar de-skewing processing, and the other part of the optical signal is output to the photoelectric detector; the photoelectric detector obtains two agile band integrated signals by heterodyne beat frequency, amplifies the two agile band integrated signals by a power amplifier, and sends them to the transmitting antenna to transmit the agile band integrated signals to free space;

[0017] The receiving antenna of the dual-agile radar detection module receives the echo signal reflected by the target object; the echo signal is amplified by a low-noise amplifier to compensate for the free space path loss, and then drives the optical phase modulator to modulate the reference optical signal, and then enters the dual-channel photon radar de-slant module through an optical power splitter to obtain de-slant signals of two agile bands respectively; the de-slant signals of the two agile bands are processed by a digital processing module to obtain a super-resolution radar image;

[0018] The receiving antenna 2 receives the agile band integrated signal, amplifies it and sends it to the incoherent communication receiving module, directly beats the agile band integrated signal to generate an intermediate frequency signal, and demodulates it to obtain communication information.

[0019] Furthermore, the processing of the digital processing module includes:

[0020] After completing analog-to-digital conversion of the de-skewed signal of each agile band, time shift and coherence compensation are performed in the time domain to obtain a large bandwidth signal;

[0021] The wide-bandwidth signal is used to fill the missing frequency bands in the frequency domain through the full-pole model to obtain an equivalent wide-bandwidth signal covering two agile bands. Combined with the inverse synthetic aperture imaging algorithm, a high-resolution radar image is obtained.

[0022] Further, the processing of the incoherent communication receiving module includes:

[0023] The envelope detector is used to beat the two agile band integrated signals with the same slope to obtain a low-frequency, single-tone intermediate frequency signal;

[0024] The frequency of the intermediate frequency signal is directly observed using a spectrum analyzer. The information of this frequency at different times is represented as different coding combinations, so the information is transmitted through the full arrangement of different intermediate frequency signals.

[0025] In summary, due to the adoption of the above technical solution, the present invention has strong information hiding ability, can be applied in complex electromagnetic environments, and is particularly suitable for the generation and reception processing of radar and communication integrated signals with low interception and anti-interference. The specific advantages are as follows:

[0026] 1. The present invention can tune the center frequency of the transmitted signal by adjusting the center wavelength of the dual-wavelength laser to obtain an integrated signal of different frequencies.

[0027] 2. The present invention completes the generation and de-skewing of high-frequency signals in the optical domain, and the system cost is low.

[0028] 3. The present invention combines integer-order full permutation combination signals with Lehmer codes to obtain a frequency-agile signal sequence of the kth combination sequence, which has the advantage of a large amount of information.

[0029] 4. The signals of agile band 1 and agile band 2 of the present invention are disordered. Only when the signal sequence of agile band 1 is mastered can the required communication information be obtained by the beat frequency combination of the two agile band signals, so that the system has strong information hiding ability.

[0030] 5. The present invention achieves high-resolution radar imaging function through radar sub-band coherent synthesis algorithm. BRIEF DESCRIPTION OF THE DRAWINGS

[0043] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Generally, the components of the embodiments of the present invention described and shown in the drawings here can be arranged and designed in various different configurations.

[0044] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the invention claimed for protection, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0045] Example

[0046] Figure 1 The block diagram of a frequency-fully-arranged agile photonics synaesthesia integrated device is shown, comprising: a photonics agile frequency-synaesthesia integrated signal generating module 10, a dual-agile radar detection module 20 and a large-information communication receiving module 30.

[0047] The photonics agile frequency conversion and interaceptive integrated signal generating module 10 comprises a dual-wavelength laser 101, a dual-band agile integrated waveform generating module 102, a dual parallel light modulator 103, an optical filter 104, an optical coupler 105, a photodetector 106, a power amplifier 107 and a transmitting antenna 108; the dual-band agile integrated waveform generating module 102 is connected to the dual parallel light modulator 103; the output end 1 of the dual-wavelength laser 101 is connected to the input end 1 of the optical coupler 105 via the dual parallel light modulator 103 and the optical filter 104 in sequence, and the output end 2 of the dual-wavelength laser 101 is connected to the input end 2 of the optical coupler 105; the output end of the optical coupler 105 is connected to the photodetector 106, the power amplifier 107 and the transmitting antenna 108 in sequence;

[0048] The dual agile radar detection module 20 includes a receiving antenna 201, a low noise amplifier 202, an optical phase modulator 203, an optical power splitter 204, a dual-channel photon radar de-skewing module 205 and a digital signal processing module 206 connected in sequence; the optical phase modulator 203 is also connected to the output end of the optical coupler 105;

[0049] The large amount of information communication receiving module 30 includes a receiving antenna 2 301 and a non-coherent communication receiving module 302 which are connected in sequence.

[0050] like Figure 2 As shown, the dual-band agile integrated waveform generation module 102 includes two multipliers. Through the two multipliers, the completely identical linear frequency modulation signal is divided into two paths, and after being multiplied with the N1-order frequency full-permutation agile frequency modulation signal and the N2-order frequency full-permutation agile frequency modulation signal, the up-conversion operation is completed to obtain the agile band 1 linear frequency modulation signal and the agile band 2 linear frequency modulation signal with different initial frequencies. The two agile band linear frequency modulation signals have the same slope, pulse width, and frequency modulation slope, and the information is transmitted by organizing the initial frequency in the form of integer full permutation. When the unit is bit, the amount of information is expressed as: I(x i )=-log 2 P(x i ), where i∈[1,D], D is the number of possible situations in the event, x i For a specific situation, P(x i ) is x i The probability of occurrence, I(x i ) is x i The corresponding amount of information. From the expression, we can see that the amount of information in the message is closely related to its probability of occurrence. The smaller the probability of the message, the greater the amount of information contained in the message. When the two agile bands each have 10 different initial frequencies to choose from, the corresponding total number of permutations is 10! = 3628800. After the two are de-skewed, the corresponding number of permutations is 10! × 10!. Therefore, the amount of information carried by each permutation is Far greater than the amount of information transmitted by conventional communication signals.

[0051] like Figure 3 As shown, the generation of the N1-order frequency full permutation agile frequency signal and the N2-order frequency full permutation agile frequency signal is as follows: Assuming that the effective length of the signal is N, obtain a random number k (i.e., the information to be transmitted), and obtain the kth combination of the N-order (N1-order or N2-order) full permutation through the Lehmer code. First, initialize, set x=k-1, y=0, i=1, and then judge the termination condition. When x is not equal to 1, assign the quotient of x divided by (N-1)! to x, y is equal to the remainder, i=i+1, and enter the termination condition again for judgment until the condition is met. At this time, the corresponding Lehmer code sequence is deduced through the previous values ​​of x and N, and then the kth combination sequence is obtained, and the agile frequency signal is obtained after multiplying by the same initial frequency.

[0052] The working method of the frequency-fully-arranged agile photonics synaesthesia integrated device is as follows:

[0053] The dual-wavelength laser 101 generates a center frequency of f 1 Continuous optical carrier (such as Figure 4 C) and input into the dual parallel optical modulator 103; the dual-wavelength laser 101 is composed of two lasers, and the generation of millimeter-wave or even terahertz signals is realized in the optical domain by combining and beating the two lasers, eliminating the expensive devices of high-cost and high-complexity harmonic mixing in the electrical domain, and adjusting the center wavelength of the second laser to achieve free tuning of the center frequency of the integrated signal; the center frequencies generated by the dual-band agile integrated waveform generation module 102 loaded by the dual parallel optical modulator 103 are f A 、f B The agile band 1 linear frequency modulation signal (such as Figure 4 A) and agile band 2 chirp signal (such as Figure 4 Then, by properly adjusting the bias point, the power of the optical carrier is suppressed, leaving only the +1st and -1st order sidebands of the signal (such as Figure 4 Medium D and Figure 4 Then, the optical filter 104 selects the two agile band linear frequency modulation signals of the upper sideband (such as Figure 4 At the same time, the dual-wavelength laser 101 generates a center frequency of f 2 A continuous optical signal (such as Figure 4 G), and then the optical coupler 105 couples the two optical signals together (such as Figure 4In H), a part of it is injected into the optical phase modulator 203 of the dual agile radar detection module 20 as a reference optical signal for radar de-skewing processing, and the other part is output to the photodetector 106, and the center frequency is obtained by heterodyne beat frequency. 1 -f 2 +f A and f 1 -f 2 +f B The two agile band integrated signals (such as Figure 4 I), by adjusting f 2 The two agile band integrated signals with different center frequencies are realized; then the two agile band integrated signals are amplified by the power amplifier 107 and sent to the transmitting antenna 108 to transmit the agile band integrated signals;

[0054] In the dual-agile radar detection module 20, the receiving antenna 1 201 receives the echo signal reflected by the target object, compensates for the free space path loss through the low noise amplifier 202, and then drives the high-speed optical phase modulator 203 to modulate the reference optical signal, and the optical signal is divided into two paths at a ratio of 50:50 through the optical power splitter 204, and injected into the dual-channel photon radar de-slant module 205 (such as Figure 4 K), realize two agile band radar pulse compression processing, and obtain two de-slanted signals (respectively as Figure 4 L and M in 4), wherein the dual-channel photon radar de-slant module 205 is composed of an optical filter, a photodetector and an electrical filter; through the digital signal processing module 206, after completing the analog-to-digital conversion of the de-slant signal of each agile band, time shift and coherence compensation are performed in the time domain to obtain a large-bandwidth signal, and then the large-bandwidth signal is filled with the missing frequency band in the frequency domain through the full-pole model to obtain an equivalent large-bandwidth signal covering two agile bands, and a high-resolution radar image is obtained by combining the inverse synthetic aperture imaging algorithm;

[0055] In the large information volume communication receiving module 30, the receiving antenna 2 301 captures the agile band integrated signal after wireless transmission, amplifies it and sends it to the incoherent communication receiving module 302 (such as Figure 4 In the process of J, two agile band integrated signals with the same slope are beat by an envelope detector to obtain a low-frequency, single-tone intermediate frequency signal. The frequency of the intermediate frequency signal is then directly observed using a spectrum analyzer. The information of this frequency at different times is represented as different coding combinations, so information can be transmitted through the full arrangement of different intermediate frequency signals.

[0056] An example is as follows:

[0057] Firstly, the signal parameters of the dual-band agile integrated signal generating module with full frequency permutation are set as follows: the initial frequency of the reference band LFM signal is 1 GHz, the bandwidth B is 1 GHz, and the pulse period is 1 μs; the interval band bandwidth dB is 1 GHz; the bandwidth and pulse period of the agile band LFM signal are the same as those of the reference band, and the agile step frequency df is 1 GHz; the effective length N of the communication information carried is 10, the random number k is 1000000, and the obtained Lehmer code sequence is: 3-8-9-4-10-2-6-5-7-1.

[0058] Then, the center frequency of the single tone signal driving the dual parallel optical modulator is 40 GHz. Therefore, a millimeter-wave dual-band agile integrated signal is generated, and its spectrum and time-frequency diagram are shown in Figure 5a , Figure 5b It can be seen that the frequency coverage range of the agile integrated signal is 81 GHz to 93 GHz.

[0059] Finally, the two functions are demonstrated through the large amount of information communication receiving module. The results are as follows: Figure 6a and Figure 6b shown.

[0060] This scheme can provide a feasible solution for low-cost, anti-interference, and high-spectrum-efficiency radar communication integrated signal generation for future multifunctional integrated RF systems.

[0061] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
