Description

Technical Field

[0001] The present invention relates to the technical field of non-cooperative signal detection, and in particular to a high-performance data acquisition and analysis and broadband receiving method and device. Background Art

[0002] The raw data acquisition of radiation source signals is one of the important functions in the field of non-cooperative signal detection and analysis. In order to obtain the rich intra-pulse modulation information and subtle features of broadband signals, the high-fidelity acquisition of broadband signals by the detection equipment is particularly important. At the same time, with the development of phased array systems, the use of multi-beam forming technology has solved the contradiction between the higher the antenna gain and the narrower the coverage space, so the development of wide space and high-gain raw data acquisition technology is imperative.

[0003] In order to improve the signal interception probability, effective range and azimuth measurement accuracy of non-cooperative detection systems, large-scale antenna arrays are increasingly widely used, and multi-beam synthesis is used to achieve wide airspace and long-distance detection capabilities. Analog beamforming technology uses time delay or phase control methods to achieve multi-beam synthesis, but its wide-band operation has a degradation in beam performance and is rarely used in wide-band, wide airspace, and high-precision detection fields. The frequency domain digital beamforming system has convenient channel calibration, flexible beam pointing adjustment, and high direction finding accuracy. The hardware resources required when multiple beams cover a wide airspace at the same time are relatively less than those of time domain digital beamforming, so it is widely used.

[0004] When using frequency domain digital beamforming for signal detection, discrete Fourier transform (DFT) processes intermediate frequency signals in segments, and after beamforming, multiple frames are spliced ​​to restore pulses and measure them. However, the original data after DFT segment processing cannot be restored with high fidelity, resulting in data distortion and inability to perform accurate analysis. At the same time, in the field of array signal processing, the wider the signal frequency bandwidth, the higher the data transmission requirements, and the more difficult the hardware implementation is. Summary of the 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.

[0041] Example

[0042] like Figure 1 As shown, this embodiment provides a high-performance data acquisition and analysis and broadband receiving device, including:

[0043] Antenna array, RF front end, integrated RF module, signal acquisition module, frequency domain digital beamformer, signal processor, analog beamforming network, broadband acquisition module, storage array and signal fusion device;

[0044] The antenna array is connected to the input end of the RF front end; the first output end of the RF front end is connected to the signal fusion device via the integrated RF module, the signal acquisition module, the frequency domain digital beam former and the signal processor in sequence; the second output end of the RF front end is connected to the storage array via the analog beam forming network and the broadband acquisition module in sequence; the broadband acquisition module is also connected to the signal fusion device; the signal processor is also connected to the analog beam forming network.

[0045] The functions of each module in the device are as follows:

[0046] The antenna array and the RF front end realize the reception, amplification and filtering of the spatial radiation source signal. The size of the antenna array is related to the demand for receiving the signal, and the RF front end generally corresponds to the antenna array.

[0047] The integrated RF module realizes amplification, filtering, combining or frequency conversion of multi-channel RF signals, and the functional composition of the integrated RF module can be adjusted according to the specific system configuration; the signal acquisition module realizes analog-to-digital conversion of the signal modulated by the integrated RF module.

[0048] The frequency domain digital beamformer realizes Fourier transform of array multi-channel signals, forms multi-beam synthesis covering a wide spatial domain through the control of beam weighting coefficients, and outputs the synthesized signal to the signal processor.

[0049] The signal processor detects multiple signals, obtains the azimuth, frequency, time, bandwidth, amplitude and phase of the spatial signal, and forms parameter description information of the radiation source signal. For the signal to be collected, the azimuth and frequency information are used to look up the table or calculate the amplitude and phase required for the simulation beamforming. If multiple signals are collected, multiple sets of beamforming parameters need to be generated.

[0050] The analog beamforming network controls the beamforming network beam synthesis output according to the input channel signal. Here, the multi-beam includes two design methods, one is that the beamforming network simultaneously outputs multiple beams with relatively fixed directions, and the other is that multiple beamforming networks form flexible multiple beams.

[0051] The broadband acquisition mainly realizes the frequency conversion and high-fidelity acquisition of broadband signals, or direct RF sampling, and its main characteristics are high sampling rate, large number of effective bits, and large spurious-free dynamic range.

[0052] The storage array is used to store the original data of the radiation source signal, and has the functions of pipeline storage and offline downloading.

[0053] The signal fusion device includes two functions: one is the synthesis of pulse signals, and the other is the fusion of the acquisition branch and the detection branch signals, and outputs the pulse signal after statistics. When the wide and narrow bands are used in combination, the result after the wide and narrow band signal fusion processing is adopted.

[0054] In some optional schemes, the device also includes a broadband signal processor; the broadband acquisition module is connected to the storage array via the broadband signal processor; the broadband signal processor is also connected to the signal fusion device. The broadband signal processing mainly realizes broadband signal detection and raw data guided storage. The broadband signal processor outputs the pulse parameters, intra-pulse modulation information and waveform characteristic parameters of the broadband signal, which can be used for the generation of high-fidelity parameters of broadband signals, and can also be used for the broadband and narrowband combined system to realize wide spatial domain, wide frequency domain and high gain reception. If there is no signal detection requirement, the broadband signal processor can be omitted.

[0055] Based on the above-mentioned high-performance data acquisition analysis and broadband receiving device, a high-performance data acquisition analysis and broadband receiving method can be implemented, including the following steps:

[0056] S1, the antenna array and the RF front end receive the spatial radiation source signal in amplitude and phase consistency; the RF front end divides the received signal into two groups, one group of signals is input into the analog beamforming network, and the other group of signals is input into the frequency domain digital beamformer via the integrated RF module and the signal acquisition module in turn;

[0057] S2, the frequency domain digital beamformer synthesizes the input signal into multiple beams covering a wide spatial domain, and its directional pattern expression is:

[0058]

[0059] Where M is the number of beams, m is the beam index, and θ is the angle of the radiation source. is the maximum directivity of the antenna beam, d is the element spacing of the antenna array, and λ is the wavelength of the operating frequency.

[0060] S3, the signal processor uses multiple beams synthesized by the frequency domain digital beam former to perform multi-beam, high-gain non-coordinated reception of the spatial radiation source signal. The received signal Y(t) is expressed as:

[0061]

[0062] Where W H is the weight vector, is the weight of the mth beam direction, S(t) represents the spatial radiation signal, s m (t) represents the radiation signal in the mth beam direction.

[0063] Then, after threshold detection, the parameter description information of the radiation source signal is formed. Among them, DOA i ,t i 、f i , BW i , A i , It represents the direction finding azimuth, interception time, carrier frequency, signal bandwidth, signal amplitude and phase of the i-th signal.

[0064] Then, the amplitude and phase control parameters of the analog beamforming network are obtained according to the parameter description information of the radiation source signal: (DOA i ,f i ) Table lookup or real-time calculation to obtain the amplitude and phase control parameters for controlling the analog beamforming network in Represents the amplitude and phase weighted information of the Nth channel required to form a beam, and then inputs it into the analog beamforming network;

[0065] S4, the analog beamforming network synthesizes the input signal into a signal of a specified direction according to the amplitude and phase control parameters; multiple sets of beamforming resources can be designed here to adapt to the simultaneous realization of multiple beam synthesis.

[0066] S5, the broadband signal acquisition module performs signal frequency conversion and high-fidelity acquisition, or RF direct acquisition, on the signal output by the analog beamforming network; preferably, in order to improve the acquisition performance, an AD or acquisition method with a large number of effective bits and a high spurious-free dynamic range is selected as much as possible while meeting the bandwidth. The acquired signal is input into the storage array for storage on the one hand, and into the signal fusion device on the other hand;

[0067] In some optional solutions, when the device has a broadband signal processor, the collected signal is processed by the broadband signal processor and then input into the storage array for storage and into the signal fusion device. Further, the broadband signal processor processes the collected signal:

[0068] On the one hand, boot storage is performed so as to be input into the storage array for storage;

[0069] On the other hand, broadband signal detection and intra-pulse feature and waveform feature extraction are performed, and the detection and extraction results are input into the signal fusion device.

[0070] S6, the signal fusion device combines the input signal with the parameter description information of the radiation source signal output by the signal processor The signal description words are generated and output.

[0071] Based on the above high-performance data acquisition analysis and broadband receiving device, a high-performance data acquisition analysis and broadband receiving method combining relatively narrowband frequency domain beamforming with broadband analog beamforming can also be implemented, including the following steps:

[0072] S1, the antenna array and the RF front end receive the spatial radiation source signal in amplitude and phase consistency; the RF front end divides the received signal into two groups, one group of signals is input into the analog beamforming network, and the other group of signals is input into the frequency domain digital beamformer via the integrated RF module and the signal acquisition module in turn;

[0073] S2, a frequency domain digital beamformer synthesizes the input signal into multiple beams covering a wide spatial domain;

[0074] S3, the signal processor uses multiple beams synthesized by the frequency domain digital beam former to perform multi-beam, high-gain non-coordinated reception and threshold detection on the spatial radiation source signal to form incomplete parameter description information of the radiation source signal Among them, DOA i ,t i , Tf i TBW i , A i , Indicates the direction finding azimuth, interception time, partial (or incomplete) carrier frequency, partial (or incomplete) signal bandwidth, signal amplitude and phase of the i-th signal; then obtains the amplitude and phase control parameters for controlling the analog beamforming network according to the incomplete parameter description information of the radiation source signal, and inputs them into the analog beamforming network;

[0075] S4, the analog beamforming network synthesizes the input signal into a signal of a specified direction according to the amplitude and phase control parameters;

[0076] S5, the broadband signal acquisition module acquires the signal output by the analog beamforming network; the acquired signal is input into the storage array for storage and into the signal fusion device;

[0077] S6, the signal fusion device converts the input signal Incomplete parameter description information of the radiation source signal output by the signal processor Fusion generates signal description words And output.

[0078] The above two high-performance data acquisition and analysis and broadband reception methods can be used in combination or separately, and the two do not conflict with each other. In addition, the frequency domain direction finding accuracy is generally between 1 / 5 and 1 / 10 of the beam width. The requirement for the beam pointing accuracy of the analog beamforming network is within 5 times of the direction finding accuracy, which meets the use requirements. For occasions where the signal-to-noise ratio requirement is not high, it can be relaxed to 10 times the direction finding accuracy to facilitate the design of the analog beamforming network.

[0079] Example:

[0080] according to Figure 1 A 60-element uniform antenna array is designed to cover frequencies from 1 GHz to 3 GHz. The frequency domain digital beamformer has an operating bandwidth of 100 MHz, forming 60 beams covering 100° in the spatial domain. The analog beamforming network instantly forms one beam for broadband signal acquisition and broadband signal processing. The instantaneous working bandwidth of broadband signal acquisition and broadband signal processing is 1 GHz. The center frequencies of the two signals radiated in space are 1.1 GHz and 2.5 GHz, respectively, with bandwidths of 150 MHz and 500 MHz, respectively, the pulse repetition periods are 1 ms and 1.2 ms, and the incident angles are 20° and 89°, respectively.

[0081] (1) The antenna array, RF front end, integrated RF module and signal acquisition module receive the signals from the space radiation source in amplitude and phase consistency, and output 60 channels of AD quantized digital signals. The RF front end divides the signals received by the antenna into two groups; one group of signals is input into the analog beamforming network, and the other group of signals is input into the frequency domain digital beamformer through the integrated RF module and signal acquisition module in turn;

[0082] (2) The frequency domain digital beamformer has an operating bandwidth of 100 MHz. It forms 60 beams within each operating bandwidth and searches the operating frequency band from 1 GHz to 3 GHz with a working cycle of 50 ms. The time required to complete the search of the entire frequency band is 1 s.

[0083] (3) Signal S is detected during the search process 1 , measure its direction, frequency and other parameters, and quickly guide the analog beamforming network to form a collection beam for the 1GHz to 2GHz frequency band. The digital beam and analog beam coverage are shown below: Figure 2 As shown, the solid line indicates the frequency domain beam, and the dotted line indicates the simulation beam.

[0084] (4) After analog beam synthesis, broadband acquisition completes the analog-to-digital conversion of one beam signal and sends it to the broadband signal processor, which completely measures its signal frequency and bandwidth, analyzes its intra-pulse modulation parameters, and outputs it to the signal fusion device, which realizes the fusion of wide-band and narrow-band signals and outputs a complete signal description word. At the same time, the broadband signal processor guides the high-fidelity raw data to be stored in the storage array.

[0085] (5) After the 50ms working cycle ends, continue scanning until the signal S is found 2 , repeat steps (3) and (4) to completely intercept the broadband signal.

[0086] Through the above implementation examples, it can be seen that the high-performance data acquisition analysis and broadband reception method and device of the present invention not only realizes the high-probability interception of wide spatial domain and high-gain frequency domain digital beamforming, but also realizes the broadband complete acquisition of multiple signals within the coverage spatial domain; at the same time, it realizes the broadband signal complete detection function of frequency domain narrowband low-cost guided broadband analog beamforming.

[0087] 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.
