[0002] With the rapid development of radar detection technology, millimeter-wave detectors are widely used in military, aviation, maritime, and automotive fields. Currently, the application of millimeter-wave detectors in the military field mostly employs discrete designs, primarily used in large-caliber missile-borne systems. This approach suffers from problems such as susceptibility to environmental interference, poor ranging accuracy, and large size and weight. Furthermore, their resistance to high overload under high-speed carrier motion, miniaturization, and wide drop angle adaptability still face technical bottlenecks, failing to meet the requirements for application on diverse missile-borne platforms. Therefore, research on millimeter-wave detectors is necessary.

Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0051] like Figure 1 As shown in the figure, this application provides a millimeter-wave detector that integrates target detection and firing control, including: an antenna array, a radio frequency processing unit, a signal processing unit, a power supply unit, a housing 2, a cover plate 3, and an antenna radome 4.

[0052] The antenna array, the radio frequency processing unit, and the signal processing unit are integrated on the circuit board 1 through three-dimensional stacking.

[0053] The power supply unit is integrated on circuit board 1.

[0054] The circuit board 1 is fixedly disposed in the cavity formed by the outer shell 2 and the cover plate 3.

[0055] The outer shell 2 is fixedly connected to the cover plate 3.

[0061] The signal processing unit is also used to analyze the echo digital signal and determine whether to send an ignition signal to the carrier's control module based on the analysis results.

[0062] The power supply unit is used to supply power to the antenna array, the radio frequency processing unit, and the signal processing unit.

[0063] Specifically, in this embodiment, the power supply unit consists of a DC-DC power chip JW5263SL, a linear regulator AP2125K-3.3TRG1, and their peripheral circuitry, integrated on circuit board 1, and is used to power the antenna array, radio frequency processing unit, and signal processing unit. The power supply unit is connected to an external power source via wires.

[0064] In this embodiment, the entire circuit board 1 is only φ18mm*4.5mm in size. The circuit board 1 is placed in the housing 2, and then the cover plate 3 is placed on top. Screws are used to fix the housing 2, circuit board 1, and cover plate 3 together. The circuit board 1 uses the IWR6843 millimeter-wave sensor chip. By integrating the antenna array, radio frequency processing unit, and signal processing unit in three dimensions, the structure of the entire circuit board 1 is very lightweight, achieving the purpose of weight reduction and optimization.

[0065] In this embodiment, the radome 4 is located at the very front of the entire millimeter-wave detector. From front to back, the components are radome 4, cover plate 3, circuit board 1, and outer shell 2. The outer shell 2 has threads, and the inner side of the radome 4 also has threads. The radome 4 and the outer shell 2 are connected by threads.

[0066] In this embodiment, the radio frequency processing unit performs radio frequency processing on the continuous triangular wave signal, including up-conversion, filtering, and power amplification on the continuous triangular wave signal in sequence to obtain a millimeter wave signal.

[0067] The radio frequency processing unit performs radio frequency processing on the echo signal, including converting the echo signal into an electrical signal and then performing low-noise amplification, down-conversion, filtering, and power amplification in sequence, before converting it into a digital signal, namely the echo digital signal.

[0068] like Figure 2 The diagram shows the bottom structure of the outer casing 2. It can be seen that the bottom of the outer casing 2 has a cable outlet 21 and a software upgrade port 22.

[0069] For example, the signal processing unit is equipped with a wide-area adaptive ranging algorithm and a dynamic Doppler compensation algorithm.

[0070] The wide-area adaptive ranging algorithm is used to analyze the echo digital signal, calculate the signal-to-noise ratio and target distance, dynamically adjust the transmission power of the continuous triangular wave signal and the sampling rate of the echo signal according to the signal-to-noise ratio and target distance, and determine whether to send an ignition signal to the control module of the carrier based on the target distance.

[0071] The dynamic Doppler compensation algorithm is used to perform dynamic Doppler compensation on the echo digital signal.

[0072] For example, the wide-domain adaptive ranging algorithm includes: The signal-to-noise ratio is calculated based on the echo digital signal.

[0073] The target distance is calculated using a dynamic Doppler compensation algorithm.

[0075] The system dynamically adjusts the transmission power of the continuous triangular wave signal and the sampling rate of the echo signal based on the signal-to-noise ratio and the target distance, and determines whether to send an ignition signal to the carrier's control module based on the target distance.

[0076] Specifically, in this embodiment, the formula for calculating the signal-to-noise ratio (SNR) based on the echo digital signal is as follows: .

[0077] A sliding window statistical noise basis was used, and the mean of 1024 sampling points was taken as the noise estimate P. 噪声 Signal power P 信号 The peak energy is calculated using FFT, as shown in the following formula: .

[0078] Where N is the number of FFT points.

[0080] The target distance R is calculated by extracting the difference frequency signal using the dynamic Doppler compensation algorithm, as shown in the following formula: .

[0081] Where c is the speed of light, T is the modulation period, B is the bandwidth, and f peak This is the peak frequency of the FFT (difference frequency signal frequency).

[0082] Output target distance R (accuracy ±0.5m).

[0083] Based on the short-time Fourier transform (STFT) analysis of the time shift characteristics of the difference frequency signal, the Doppler frequency shift is extracted. Calculate the radial velocity vradial As shown in the following formula: .

[0084] in =c / B is the wavelength (at 64GHz). ≈4.7mm).

[0085] The acceleration is calculated using the Doppler frequency shift difference between adjacent frames, as shown in the following formula: .

[0086] Where Δt is the frame interval.

[0087] Output radial velocity v radial (Accuracy ±0.1m / s) and acceleration a radial (Accuracy ±0.05m / s) 2 ).

[0088] If SNR < 15dB or R > 50m, increase the transmit power: P 发射new =P 发射old +ΔP (15-SNR), (ΔP=0.5dB / step).

[0089] If SNR > 25dB or R < 15m, then reduce the transmit power: P 发射new =P 发射old -0.2dB / step, with a minimum sensitivity threshold.

[0090] If R > 50m (long distance), reduce the bandwidth to 100MHz, and reserve 10% redundancy for the sampling rate to match the signal bandwidth. s =1.1×2B, which is 220MS / s.

[0091] If R < 15m (close distance), increase the bandwidth to 500MHz, and reserve 10% redundancy for the sampling rate to match the signal bandwidth. s =1.1×2B, which is 1.1GS / s.

[0092] Finally, when the target distance R = 10m ± 1m, the signal processing unit continuously sends an ignition signal to the carrier's control module.

[0093] For example, the dynamic Doppler compensation algorithm includes: After the short-time Fourier transform, the Doppler factor is calculated.

[0094] A frequency domain compensation matrix is ​​constructed based on the Doppler factor.

[0095] A frequency domain compensation matrix is ​​used to compensate the spectrum of the echo digital signal.

[0098] Kalman filtering is used to track the target motion state, the Doppler factor is updated in real time, the recovered time domain signal is output, and accurate time delay information is extracted.

[0099] Specifically, in this embodiment, after the short-time Fourier transform, the Doppler factor α is calculated for subsequent signal compensation: .

[0100] Constructing the frequency domain compensation matrix C based on the Doppler factor: .

[0101] Where A is the Doppler frequency matrix and B is the discrete-time Fourier transform matrix.

[0102] The frequency domain compensation matrix is ​​used to compensate the spectrum of the echo digital signal as follows: .

[0103] Where X(k) is the original spectrum and Y(k) is the compensated spectrum.

[0104] The time-domain signal is recovered from the compensated spectrum using an IFFT operation as follows: .

[0105] Calculate the residual between the recovered time-domain signal and the theoretical echo model, and adjust the Doppler factor using the minimum mean square error: .

[0106] Kalman filtering is used to track the target motion state, the Doppler factor is updated in real time, the recovered time domain signal is output, and accurate time delay information is extracted.

[0107] For example, the cover plate 3 has a trapezoidal slot, which is used to expose the antenna array.

[0108] For example, the cover plate 3 is provided with a filling port and an exhaust port.

[0109] The filling port is used to fill the cavity formed by the outer shell 2 and the cover plate 3. After the filling is completed, there is no cavity in the cavity formed by the outer shell 2 and the cover plate 3.

[0110] The vent is used to release air during potting.

[0111] Specifically, in this embodiment, the cover plate 3 is provided with three φ3mm holes, one of which serves as a filling port and the other two as venting ports.

[0112] For example, the potting material used is epoxy resin adhesive.

[0113] Specifically, in this embodiment, the epoxy resin adhesive is type 150B, which has good fluidity and can ensure that no cavities are generated inside after potting.

[0114] For example, both the outer shell 2 and the cover plate 3 are made of aluminum alloy composite material.

[0115] Specifically, in this embodiment, the aluminum alloy composite material is 7075 aluminum alloy.

[0116] For example, the radome 4 is made of polyphenylene sulfide material.

[0117] Specifically, by using an aluminum alloy composite material shell 2, a cover plate 3, and a polyphenylene sulfide material antenna radome 4, the weight of the millimeter-wave detector is reduced while also achieving impact resistance and high-temperature resistance.

[0118] For example, the signal processing unit is provided with an anti-false triggering mode and a continuous triggering mode.

[0119] The anti-false triggering mode includes: when the speed of the carrier is less than a preset speed threshold, the signal processing unit does not send an ignition signal to the carrier's control module.

[0120] The continuous triggering mode includes: when the speed of the carrier is greater than or equal to a preset speed threshold and the correction distance is less than a preset distance threshold, the signal processing unit continuously sends an ignition signal to the control module of the carrier.

[0121] Specifically, the purpose of the anti-false triggering mode is to prevent false triggering during production and debugging by providing an ignition signal. The target relative speed must be greater than or equal to 1 m / s to send an ignition signal to the control module via the data line. The continuous triggering mode is designed to ensure a high success rate in sending an ignition signal to the control module when the carrier is at a given distance.

[0122] Specifically, in this embodiment, the operation of the millimeter-wave detector is as follows: Ranging phase: Once the carrier reaches the millimeter-wave detection range, a wide-area adaptive ranging algorithm is used to analyze the echo digital signal, calculate the signal-to-noise ratio and target distance, and dynamically adjust the transmission power of the continuous triangular wave signal and the sampling rate of the echo signal based on the signal-to-noise ratio and target distance.

[0123] Compensation stage: The dynamic Doppler compensation algorithm is used to perform dynamic Doppler compensation on the echo digital signal. The distance error is corrected based on velocity estimation. The minimum ranging accuracy for high-speed flying missiles can reach 0.15m.

[0124] Output phase: Based on the target distance, determine whether to send an ignition signal to the carrier's control module to ultimately achieve the detonation operation.

[0125] In one possible embodiment, the millimeter-wave detector of this application is applied to a certain type of 120mm mortar grenade. When the projectile's rotational speed is 0-8 revolutions per second, its impact velocity is 100m / s-400m / s, its impact angle is 25°-65°, and its altitude above the ground target is 3±1 meters, a proximity ignition signal is output, achieving an integrated application of target detection and ignition control.

[0126] In another possible embodiment, the millimeter-wave detector of this application is applied to a certain type of rocket. When the rocket's rotational speed is 0-300 rpm, its impact velocity is 100 m / s-600 m / s, its impact angle is 20°-70°, and its altitude above the ground target is 10±1 meters, a proximity ignition signal is output, achieving an integrated application of target detection and ignition control.

[0127] This application embodiment integrates the antenna array, radio frequency processing unit, and signal processing unit through three-dimensional stacking. Combined with the structural design of the entire millimeter-wave detector, it achieves both target detection and firing control in one unit while being lightweight and miniaturized, thus meeting the application requirements of diverse missile-borne platforms.

[0128] The proposed signal processing unit incorporates a wide-domain adaptive ranging algorithm and a dynamic Doppler compensation algorithm, improving the accuracy and reliability of target range estimation. It issues a firing signal at a set distance to maximize lethality.

[0129] The proposed cover plate 3 has trapezoidal slots, which are used to expose the antenna array. Together with the antenna cover, it can meet the detection range of a large angle when approaching the target, and can adapt to the angle of impact range of 20° to 70°.

[0130] The proposed cover plate 3 is equipped with a filling port and an exhaust port. The filling port is used to fill the cavity formed by the outer shell 2 and the cover plate 3. After filling, the cavity formed by the outer shell 2 and the cover plate 3 has no empty space, which can ensure that it functions well under high overload conditions during transmission. The filled millimeter-wave detector can withstand overloads of over 32,500g.

[0131] The proposed signal processing unit is equipped with an anti-false triggering mode and a continuous triggering mode. The anti-false triggering mode avoids false triggering during production and debugging, while the continuous triggering mode ensures the success rate of the carrier sending an ignition signal to the control module at a given distance.

[0132] The millimeter-wave detector of this application has a final weight of ≤40g after potting, which is at least 500% lighter than existing millimeter-wave detectors used on missiles, and is suitable for missile diameters ranging from 50mm to 300mm.
