Description

Technical Field

[0001] This invention relates to a radar echo signal simulation method and system for information agile control, belonging to the field of radar signal simulation technology. Background Technology

[0002] Information metamaterials and liquid metals, as emerging artificial electromagnetic materials, can perform agile information control of electromagnetic signals. Their core lies in achieving dynamic control of unit structures through digital information encoding, utilizing digital characterization methods to perform real-time, precise, and multi-dimensional control of the amplitude, phase, and polarization parameters of incident electromagnetic waves. With their outstanding flexibility and adjustability, the agile information control capabilities of these materials have spurred a series of cutting-edge applications in the radar field, significantly expanding the functionality and application scope of radar systems.

[0003] The digital characterization of information-agile control materials and the digital signal processing technology of radar systems have a natural theoretical fit. However, current research on information-agile control mainly focuses on the electromagnetic field level analysis of materials, especially electromagnetic properties such as scattering parameters and radiation modes. While these studies have revealed the basic performance of materials in achieving information-agile control to some extent, they differ significantly from the echo signal level analysis required for radar system design and verification. For example, in radar target detection applications, to evaluate the impact of information-agile control on radar signal processing, it is necessary to simulate and verify its specific mechanism of action from the perspective of the echo signal. In addition, the radar echo experimental verification of information-agile control generally requires the design, preparation, indoor and outdoor testing of information-agile control materials, which is characterized by high cost and low efficiency.

[0004] Traditional radar echo simulation methods have formed a relatively mature system, typically including target scattering modeling based on electromagnetic calculations, radar wave propagation models, and time-domain and frequency-domain analysis of target echo signals. These methods mainly focus on the electromagnetic wave interaction between the target and the radar, but systematic echo simulation and analysis methods are still lacking for the signal-level modulation characteristics introduced by information-agile modulation materials, especially their application and impact in complex electromagnetic environments.

[0005] Therefore, how to equivalently integrate the electromagnetic properties of information-agile control materials into the radar echo simulation framework and conduct signal-level simulation and evaluation has become a key issue that urgently needs to be addressed in the intersection of radar technology and information-agile control materials. This will not only help further promote the application of information-agile control materials in radar systems, but also provide important theoretical basis and technical support for the design and optimization of new radars.

[0052] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present invention.

[0053] The present invention will be further described below with reference to specific embodiments.

[0054] Example 1:

[0055] This embodiment introduces a radar echo signal simulation method for information-agile control, such as... Figure 1 As shown, it includes the following steps:

[0056] Step 1: Set the simulation parameters for radar and information agile control materials.

[0057] The radar simulation parameters include: radar transmit signal carrier frequency, radar transmit signal model, radar transmit signal pulse width, radar transmit signal bandwidth, number of simulated range gate points, number of echo simulation frames, number of echo simulation pulses, radar pulse transmission period, fast time sampling frequency (fast time sampling period), and radar echo amplitude.

[0058] Simulation parameters for information-agile control materials include: number of information-agile control array elements, information-agile control frequency (information-agile control period), length of information-agile control coding sequence, information-agile control amplitude, information-agile control phase, initial radial distance of information-agile control material, and initial radial velocity of information-agile control material.

[0059] Step 2: Construct information-sensitive, all-time control signals.

[0060] Among them, information metamaterials and liquid metals possess the ability to rapidly control information. These artificial materials are arranged into arrays of units (the smallest repeating structures), and the control state of each unit is controlled through FPGA bit encoding. Considering arbitrary numbers of bits... In this situation, for a person with The array has 100 cells, and the state code for each cell is 100. The set of defined unit state codes is: Then the formation's first The state code set of each unit is of length [length missing]. Information agile control coding sequence All elements in the sequence are taken from the set. The selection can be repeated, and the sequence expression can be written as:

[0061] ψ k = [ φ 1 , k , φ 2 , k ,..., φ n , k ,..., φ N , k ] (1)

[0062] In the formula, sequence elements For the first The first unit Each control state corresponds to an information agile control phase, and the duration of each control state is one information agile control cycle. , It is the number of elements in the sequence, and .

[0063] For example, when Sometimes, , length is The information agile control coding sequence can be written as ψ k = [ 0 , 0 , 1 ] Based on the arrangement of the phases in information agile control, information agile control methods can be further classified into phase periodic control and phase random control.

[0064] Taking the center moment of the first control cycle of information agile control as the simulation zero moment, the information agile control coding sequence is converted into the form of a control signal. At this time, the first... The information agile, all-time control signal for each unit is:

[0065] (2)

[0066] In the formula, For rectangular window signals, t ∈ [ 0 , N ⋅ T m , k ] For all-day time control, For the first Information agility control cycle of each unit For the first Information on the agile adjustment range of each adjustment cycle It is the imaginary unit.

[0067] To ensure that the constructed information-agile control signal can cover the entire radar echo simulation period, the total time of the general expression (2) is... It must exceed the total time required for radar echo simulation.

[0068] Step 3: Sample the information agile full-time control signal with echo timing alignment to obtain the information agile discrete control signal matrix.

[0069] To describe the real-time nature of the information-agile control signal, the moment the radar-transmitted signal arrives at the information-agile control material is considered the start time of control. For the first... Information agility and all-time control signal of each unit The method for calculating the timing-aligned sampled sequence after echo timing alignment is as follows:

[0070] τ a , b [ n ] = t ′ [ n ] + a ⋅ B ⋅ PRT + ( b − 1 ) PRT − R a , b c (3)

[0071] In the formula, For the first Frame number The radial distance between the radar and the information-agile control material during pulse echo simulation. This refers to the frame number in the echo simulation. The pulse number is used for echo simulation. The initial radial distance and initial radial velocity of the information-agile control material were calculated. At the speed of light, t ′ [ n ] To achieve the set fast sampling frequency Time series of sampled radar echo signals The total number of simulated echo pulses, This refers to the radar pulse transmission cycle.

[0072] In order to obtain the information-agile discrete modulation signal corresponding to each radar echo signal during the simulation time... S IM , k ( τ a , b [ n ] ) First, the continuous information-agile all-time control signal is subjected to information-agile control frequency. Pre-sampling is performed to obtain pre-sampling results. Each point in the pre-sampling results corresponds to an information agile control phase. Then, based on the time-aligned sampling sequence, nearest neighbor interpolation is performed on the pre-sampling results to obtain the information agile discrete control signal. Finally, the obtained information agile discrete control signal is sorted according to dimension [echo simulation pulse number]. Radar echo signal time series length Echo simulation frame count They are combined into an information-agile discrete control signal matrix.

[0073] Figure 2 A schematic diagram illustrating the implementation of steps two through three is provided: assuming... ,have The corresponding information agile control phase is and , Figure 2 One unit is of length The “information agile control coding sequence” is written as ψ k = [ 1 , 0 , 0 , 1 , 0 , 1 , 1 , 0 , 1 , 0 ] Based on the "information agile control coding sequence", a full-time information agile control signal with a constant information agile control amplitude of 1 is constructed. The portion aligned with the radar echo signal in time is... Figure 2 The "time-aligned information agile control signal" refers to sampling the information agile control signal across all time periods with echo time alignment. Figure 2 The elongated "pre-sampling points" (intervals equal to the information agile control period, where the information agile control period and the information agile control frequency are reciprocals of each other) represent the pre-sampling results based on the information agile control frequency. The short and thick "time-aligned sampling sequence" (intervals equal to the fast time sampling period, where the fast time sampling period and the fast time sampling frequency are reciprocals of each other) performs nearest-neighbor interpolation on the pre-sampling results to obtain the information agile discrete control signal.

[0074] Step 4: Generate the original radar echo signal matrix.

[0075] Based on radar transmission signal time series and transmission signal model Generate the radar transmitted signal matrix based on the radar transmitted signal carrier frequency in the simulation parameters. Radar echo amplitude and the radial distance of each simulated pulse Generates the raw radar echo signal in baseband form for each pulse. S a , b [ n ] The calculation method is as follows:

[0076] S a , b [ n ] = E a , b S ( t ′ [ n ] − 2 R a , b / c ) exp ( − 4 π f c R a , b / c ) (4)

[0077] Finally, the original radar echo signal was sorted by dimension [number of simulated echo pulses]. Radar echo signal time series length Echo simulation frame count These are combined to form the original radar echo signal matrix.

[0078] Step 5: Generate the radar echo signal matrix for information agility control.

[0079] Radar echo signals for information agility control S ′ a , b [ n ] Equivalent digital domain modeling involves multiplying the information-agile discrete control signal matrix generated in step three with the original radar echo signal matrix generated in step four, and then adjusting the matrix based on the simulated range gate number. The radar echo signal matrix for information agility modulation is generated by intercepting the signal. The calculation method for each information agility modulation radar echo signal is as follows:

[0080] S ′ a , b [ n ] = S a , b [ n ] ⋅ ∑ k = 1 K S IM , k ( τ a , b [ n ] ) + n 0 [ n ] (5)

[0081] In the formula, n 0 [ n ] This is a noise or clutter signal.

[0082] Step Six: Perform signal analysis and processing on the simulated echo.

[0083] The echo signal obtained from the simulation in step five is subjected to digital signal processing. The specific operations include range-dimensional matched filtering and Doppler frequency analysis for narrowband radar systems, and two-dimensional imaging for broadband systems, in order to observe the impact of information agile modulation on radar echo signal processing.

[0084] Example 2:

[0085] This embodiment describes a computer-readable storage medium storing a computer program that, when executed by a processor, implements a radar echo signal simulation method for information agile control as described in any of Embodiment 1.

[0086] Example 3:

[0087] This embodiment describes a computer device, including:

[0088] Memory is used to store instructions.

[0089] A processor is configured to execute the instructions, causing the computer device to perform the operation of a radar echo signal simulation method for information agile control as described in any of Embodiment 1.

[0090] Example 4:

[0091] This embodiment constructs a virtual radar detection scenario, in which the radar beam is aimed at the information metamaterial and transmits a signal. The information metamaterial is in motion relative to the radar. The information metamaterial modulates the signal transmitted by the radar. The radar receives the echo signal after information agility modulation and performs signal processing.

[0092] According to step one, the main simulation parameters of the radar and information metamaterial in this embodiment are shown in Table 1. All units of the information metamaterial use the same control method.

[0093] Table 1 shows the main simulation parameters for radar and information metamaterials.

[0094] parameter Value (unit) parameter Value (unit) radar transmission signal carrier frequency 10 (GHz) Fast sampling frequency 20 (MHz) Radar transmission signal bandwidth 10 (MHz) Radar pulse transmission period 1 / 6000（s） Radar transmission signal pulse width 10（µs） Initial radial distance of information metamaterial 15 (km) (MHz) Radar transmission signal model Linear frequency modulation signal Initial radial velocity of information metamaterial -20 (m / s) Simulated distance gate points 1024 Information-based agile control methods Phase periodic modulation Echo simulation frame count 1 Information agile phase control 0 or 180 (°) Echo Simulation Pulse Count 64 Information agile control frequency 5 (MHz)

[0095] Taking the first pulse of the first frame as an example: Based on the information agile all-time control signal constructed in step two, simulation parameters show that the information metamaterial uses a control frequency of 5MHz to alternately encode and achieve 0° and 180° phase shifts, such as... Figure 3 As shown. Subsequently, according to the information agile full-time control signal timing sampling and echo timing alignment method in step three, the constructed information agile control signal is sampled. Since the time for the first pulse to arrive at the information metamaterial is... s, the time-aligned information agile control signal, such as Figure 4 As shown. After generating the original radar echo signal according to step four, step five involves multiplying the original echo signal by the information agile control signal to obtain the final information agile control radar echo signal, as shown. Figure 5 As shown, to more clearly demonstrate the results of information agility control, the following is presented: Figure 5 Intercepted Figure 6 The image shows the modulated radar transmit signal. The result of matched filtering on the radar echo signal with information agility modulation is shown below. Figure 7 As shown, the results of moving target detection on the first frame echo are as follows: Figure 8 As shown. For the information metamaterial in this embodiment, theoretically, the uncontrolled original echo has only one focused peak after matched filtering and moving target detection. After information agile modulation, multiple focused peaks are formed in the range dimension and Doppler dimension. Therefore, the method proposed in this invention can complete the radar echo simulation of information agile modulation.

[0096] Specifically, the innovative aspects of this invention include:

[0097] (1) Timing alignment method for information agile control signals under long-term simulation:

[0098] To address the challenges of programming information-agile control signals and sampling them according to radar echo timing during long-term simulations, this invention proposes a timing alignment method that pre-samples the control signal at the control frequency and then performs nearest-neighbor interpolation. This method first samples the discrete control code using the control frequency of the information-agile control material to generate a control signal sequence. Then, it precisely aligns this sequence to the radar system's echo time sequence using nearest-neighbor interpolation, ensuring accurate correspondence between the control signal and the radar waveform at every moment.

[0099] (2) Equivalent digital domain modeling of radar echo signals with information agile control:

[0100] This invention establishes a complete digital domain equivalent echo simulation model. This model multiplies the original radar echo signal with the information agile control signal to synthesize a radar echo signal with information agile control characteristics. This model realizes the digital simulation from "control coding" to "radar echo".

[0101] Based on the above-mentioned innovations, this invention covers the universality of the method itself, its core steps, and its application scenarios, specifically including:

[0102] (1) Wide applicability of the method: It is required that the simulation method described herein be applicable to any radar transmission signal, including but not limited to waveforms of different systems such as narrowband signals, broadband signals, pulse signals, and frequency-modulated continuous wave signals.

[0104] (3) Exclusivity of core steps: It is required to protect the core step of “information agile control signal timing sampling and echo timing alignment”, especially the specific implementation scheme of sampling at the control frequency and combining nearest neighbor interpolation to achieve synchronization with the echo timing.

[0105] (4) Coverage of application scenarios: It is required to protect the application of this method in complex scene echo simulation, that is, to be able to simulate the radar echo generation process after information agile control, including single target, multi-target and distributed scenes.
