Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the scope of protection of the present application.

[0040] In the current context, the availability, integrity and reliability of radar need to have higher requirements, otherwise unexpected collisions or abnormal trajectories during vehicle driving may occur. However, due to the lack of existing research, many manufacturers do not have safety detection technology, resulting in uneven safety levels of radar products, which are difficult to evaluate. As can be seen from the above, in the process of radar safety detection, how to avoid the uneven safety level of radar products, so as to increase the reliability and accuracy of radar safety detection is a problem to be solved in the field.

[0041] Referring to Figure 1 The embodiments of the present application disclose a radar safety detection method, which can specifically include:

[0042] Step S11: determining a target radar type, and determining a target radar safety detection method from the preset radar safety detection method library based on the target radar type.

[0043] In the embodiment, after the target radar type is determined, the target radar safety detection material information is determined from the preset detection material information library according to the target radar type, and the radar detection tool is configured according to the target radar safety detection material information to obtain the target radar detection tool. The target radar type includes but is not limited to laser radar, millimeter wave radar and ultrasonic radar.

[0044] It can be understood that after the target radar type is determined as laser radar, millimeter wave radar and ultrasonic radar, the safety detection material information of the laser radar, millimeter wave radar and ultrasonic radar is determined from the detection material information library. For example, the laser radar safety detection material information includes that the wave absorbing material is laser absorbing paint / resin, the interference material is a laser emitter matrix, a mirror and a mirror surface reflecting paint, etc. The radar detection tool is configured according to the laser radar safety detection material information, and finally the target radar detection tool is obtained. Then the target radar detection tool is powered on, and the laser radar safety detection method is determined from the preset radar safety detection method library. For example, the laser radar detection item includes detecting whether the laser radar is resistant to strong light interference. At this time, the laser radar blur test tool is needed to directly emit strong light and observe the response of the laser radar.

[0045] Step S12: acquiring a radar signal and analyzing the radar signal to obtain a radar signal wavelength and a radar signal frequency.

[0046] In the embodiment, the local signal receiver is used to acquire the radar signal, and then the signal receiver sends the radar signal to the local core board. The core board automatically analyzes the radar signal to obtain the radar signal wavelength and the radar signal frequency.

[0047] Step S13: generating a target signal based on the radar signal wavelength and the radar signal frequency, and performing radar safety detection on the target radar by using the target radar safety detection method and the target signal.

[0048] In the embodiment, the core board is used to send the radar signal wavelength and the radar signal frequency to the local frequency modulation signal generator. The frequency modulation signal generator generates a signal corresponding to the radar signal wavelength and the radar signal frequency, and then the frequency modulation signal generator sends the signal to the local signal transmitter. The local core board controls the signal by using a matrix point to obtain a target signal. After obtaining the target signal, the laser radar safety detection method is determined from the preset radar safety detection method library, and the target radar is detected by using the target signal.

[0049] In this embodiment, the target radar type is determined, and a target radar security detection method is determined from the preset radar security detection method library based on the target radar type; a radar signal is acquired, and the radar signal is analyzed to obtain a radar signal wavelength and a radar signal frequency; a target signal is generated based on the radar signal wavelength and the radar signal frequency, and the target radar is subjected to radar security detection by using the target radar security detection method and the target signal. The application is applied to a target radar detection tool, and the target radar security detection method is determined from the preset radar security detection method library, so that the situation that radar product security levels are uneven and difficult to evaluate can be effectively avoided. The radar signal is analyzed to obtain the radar signal wavelength and the radar signal frequency, the target signal is generated based on the radar signal wavelength and the radar signal frequency, and the target radar is subjected to radar security detection by using the target signal, so that the reliability and accuracy of radar security detection are increased.

[0050] Referring to Figure 2 The embodiment of the application discloses a radar security detection method, which can specifically include:

[0051] Step S21: A target radar type is determined, and a target radar security detection method is determined from the preset radar security detection method library based on the target radar type.

[0052] Step S22: A radar signal is acquired, and the radar signal is analyzed to obtain a radar signal wavelength and a radar signal frequency.

[0053] Step S23: A target signal is generated based on the radar signal wavelength and the radar signal frequency, and the target radar is subjected to radar security detection by using all the target radar security detection methods in the radar security detection method library and the target signal, so as to obtain radar security detection sub-results.

[0054] In this embodiment, after the target radar is subjected to radar security detection by using all the target radar security detection methods in the radar security detection method library and the target signal, a radar security detection picture is displayed by using a preset human-computer interaction interface of the target radar, so as to determine radar security detection sub-results based on the radar security detection picture.

[0055] Step S24: All the radar security detection sub-results are analyzed according to a preset radar security detection sub-result analysis rule, so as to obtain a radar security detection result.

[0056] It can be understood that after determining the target radar safety detection method from the preset radar safety detection method library, for example, determining that the target radar type is a millimeter wave radar, a millimeter wave radar safety detection method is determined from the preset radar safety detection method library, wherein the millimeter wave radar safety detection method includes detecting whether the millimeter wave radar can judge the high-speed running obstacle, at this time, the millimeter wave radar fuzzy test tool needs to be used, after receiving the electromagnetic wave signal, the electromagnetic wave generator directly generates the electromagnetic wave, and the signal emission time of the electromagnetic wave emitter is controlled through the delay, the millimeter wave radar disposal is observed, and whether the millimeter wave radar sensitivity is resistant to signal absorption is detected, at this time, the magnet needs to be placed in the near field of the radar, and the millimeter wave radar is operated. Obtain the radar signal, and analyze the radar signal to obtain the wavelength and frequency of the radar signal, and then generate a target signal based on the wavelength and frequency of the radar signal, and use the above millimeter wave radar safety detection method and the target signal to perform radar safety detection on the target radar to obtain a radar safety detection sub-result, for example, when detecting whether the millimeter wave radar can judge the high-speed running obstacle, if the millimeter wave radar judges that there is no obstacle, the radar safety detection sub-result is unsafe, and if the millimeter wave radar can detect the obstacle, the radar safety detection sub-result is safe. After performing radar safety detection on the target radar by using the target radar safety detection method respectively, all radar safety detection sub-results are obtained, and then all radar safety detection sub-results are analyzed according to a preset radar safety detection sub-result analysis rule to obtain a radar safety detection result.

[0057] In this embodiment, the target radar detection tool is applied, and the vehicle-mounted radar safety fuzzy test tool is taken as an example. As shown in a system architecture diagram of the vehicle-mounted radar safety fuzzy test tool, Figure 3 The application layer includes a notebook computer upper computer program, a radar upper computer and a fuzzy test conclusion. The detection engine includes a signal calculation model, an information input template and a 3D modeling algorithm model. The database includes a fuzzy test rule library and a historical test record. The signal input template is used to configure necessary parameters of the rule, such as signal delay, absorption of consumables use guide, interference intensity, high-speed simulation model and the like. The signal calculation model is used to realize signal delay control and laser emitter matrix point array control and the like.

[0058] In this embodiment, the target radar detection tool is applied, and the vehicle-mounted radar safety fuzzy test tool is taken as an example. As shown in a system architecture diagram of the vehicle-mounted radar safety fuzzy test tool, Figure 4As shown, the vehicle-mounted radar safety fuzzy testing tool consists of five hardware components: a laptop-based host computer program, a core board, a signal receiver, a frequency modulation (FM) signal generator, and a signal transmitter. The laptop-based host computer program contains a template for inputting detection rules and coordinates the signal scheduling of the core board during fuzzy testing. It can also control the addition and modification of the 3D modeling algorithm. The signal receiver receives radar signals. The core board receives the signals transmitted by the receiver and automatically analyzes the signal wavelength and frequency. It also controls the FM signal generator and the signal transmitter. The FM signal generator generates signals corresponding to the wavelength and frequency of the receiver. The signal transmitter transmits radar signals, classifying LiDAR transmitter matrices, millimeter-wave radar transmitters, and ultrasonic radar transmitters. The core board centrally manages the signal wavelength, frequency, delay, and dot matrix recursion generated after signal reception. It interacts with the user via a laptop computer, providing fuzzy testing templates for easy parameter configuration of different detection rules. A signal generator produces radar signals, which the core board then schedules for transmission. The radar host computer's response, combined with fuzzy testing criteria, leads to a conclusion. This effectively solves the current problem of inconsistent security levels and difficulty in assessing radar products.

[0059] For example, such as Figure 4 As shown, the specific process of radar security detection applied to the vehicle radar security fuzzy testing tool is as follows: First, the target radar type is determined, for example, the target radar type is lidar, millimeter-wave radar and ultrasonic radar. Then, the target radar security detection material information is determined from the preset detection material information database, as shown in Table 1.

[0060] Table 1

[0061]

[0062] The host program on the notebook computer configures the vehicle-mounted radar security fuzzy test tool according to Table 1 to obtain a target vehicle-mounted radar security fuzzy test tool, determines a target radar security detection method from the preset radar security detection method library according to the target radar type, and the specific target radar security detection method is shown in Table 2. Then, the radar is turned on and starts to work. After the signal receiver obtains the radar signal, the radar signal is sent to the core board. Then, the core board automatically analyzes the received radar signal to obtain the radar signal wavelength and the radar signal frequency. Then, the core board sends the radar signal wavelength and the radar signal frequency to the frequency modulation signal generator. The frequency modulation signal generator generates a signal corresponding to the radar signal wavelength and the radar signal frequency, and then sends the signal to the signal transmitter. The core board controls the signal by using a matrix point to obtain a target signal, and sends the target signal to the radar. The target radar is detected for radar security by using the laser radar security detection method determined from the preset radar security detection method library and the target signal. For example, the target radar is detected for radar security according to 7 laser radar detection items, the detection methods in Table 2, and the judgment basis. Then, a radar security detection screen is displayed through the man-machine interface of the radar host computer. Then, 7 laser radar security detection sub-results are determined according to the radar security detection screen and the judgment basis. When the target radar type is a laser radar, 7 radar security detection sub-results are obtained. Then, according to the target radar type being a millimeter wave radar, the notebook computer host program configures the vehicle-mounted radar security fuzzy test tool again according to Table 1. According to Table 2, the millimeter wave radar detection items are 5. The above steps are repeated. Finally, 5 millimeter wave radar security detection sub-results are obtained. Correspondingly, the ultrasonic radar finally obtains 4 ultrasonic radar security detection sub-results. Then, all the radar security detection sub-results are analyzed, that is, 16 sub-results are analyzed. Finally, the vehicle-mounted radar security detection result is obtained.

[0065]

[0066] For example, taking a laser radar as an example, detecting whether the laser radar can judge the high-speed running obstacle, detecting the availability, first, the notebook computer host program needs to be configured according to the above table 1 to obtain the target vehicle-mounted radar safety fuzzy test tool, and then the hardware circuit is powered on, the laser radar is turned on, the delay t1 of the first column of the laser signal transmitter matrix and the vertical surface signal transmission delay recursion value x in the notebook computer host program are set, and the obstacle dot matrix generated by the laser signal transmitter matrix is configured, wherein the delay t1 of the first column of the laser signal transmitter matrix is used to simulate the distance of the obstacle, and each vertical surface signal transmission delay recursion value is used to simulate the moving speed of the obstacle, and the delay time of the nth column is t1+x×(n-1). In addition, the recursion value x<0 indicates that the obstacle is close, and the recursion value x>0 indicates that the obstacle is far away, then the laser radar starts to work, after the radar signal is received by the laser signal receiver, the wavelength and frequency of the radar signal are transmitted to the core board, the core board automatically analyzes the wavelength and frequency of the signal, and sends the wavelength and frequency to the laser signal generator. The laser signal generator generates a signal, the core board combines the values set in the notebook computer host program to dispatch the dot matrix of the laser signal transmitter matrix, calculates the signal transmission delay t1+x×(n-1) by using the recursion value of each vertical surface, simulates the high-speed running obstacle, and observes the imaging result of the laser radar host computer. If the laser radar judges that there is no obstacle, it is unsafe, and if the laser radar can detect the obstacle, it is safe. Taking a millimeter wave radar as an example, detecting whether the millimeter wave radar exists object deception, detecting the reliability, first, the notebook computer host program needs to be configured according to the above table 1 to obtain the target vehicle-mounted radar safety fuzzy test tool, and then the hardware circuit is powered on, the millimeter wave radar is turned on, and the delay t of the electromagnetic wave signal transmitter in the notebook computer host program is set. The delay t of the electromagnetic wave signal transmitter is used to simulate the distance of the obstacle, then the millimeter wave radar starts to work, after the radar signal is received by the electromagnetic wave signal receiver, the wavelength and frequency of the radar signal are transmitted to the core board, the core board automatically analyzes the wavelength and frequency of the signal, and sends the wavelength and frequency to the electromagnetic wave signal generator. The electromagnetic wave signal generator generates a signal, the core board combines the values set in the notebook computer host program to dispatch the electromagnetic wave signal transmitter, transmits the signal according to the signal transmission delay t, simulates the obstacle, and then observes the disposal result of the millimeter wave radar host computer. If the millimeter wave radar misreports that there is an obstacle, it is unsafe, and if the millimeter wave radar does not misreport, it is safe.
