Description

Technical Field

[0001] This application belongs to the field of vehicle-mounted radar technology, and relates to a radar continuous interference detection device, method, equipment and medium based on alternating transmission. Background Technology

[0002] Millimeter-wave radar is widely used in modern automotive active safety and autonomous driving systems due to its advantages such as high resolution, all-weather operation, and strong environmental adaptability. With the popularization of Advanced Driver Assistance Systems (ADAS) and intelligent connected vehicles, vehicles are commonly equipped with millimeter-wave radar to achieve functions such as adaptive cruise control, blind spot monitoring, automatic emergency braking, and lane change assist. However, with the rapid increase in the installation rate of automotive millimeter-wave radar, the number of radar devices operating simultaneously on the road has increased significantly, leading to easy mutual interference between radars of different vehicles. Specifically, the millimeter-wave signal emitted by one radar may be received by radars of neighboring vehicles operating in the same or adjacent frequency bands, forming interference signals. This interference can seriously affect the target detection performance of radar, leading to false alarms, missed detections, or errors in ranging and speed measurement, thereby threatening driving safety.

[0003] Currently, research on millimeter-wave radar interference primarily focuses on suppression techniques at the signal processing and algorithm levels, such as waveform design, filtering algorithms, or time-frequency domain signal separation. However, the research and practical application of these methods depend first and foremost on the thorough acquisition and analysis of real interference signals. Existing interference data acquisition mainly relies on real-vehicle road testing. However, in real traffic scenarios, interference events are random and sporadic, making it difficult to efficiently and controllably reproduce specific interference patterns. This results in long data acquisition cycles, high costs, and a lack of systematic coverage of various interference scenarios. Furthermore, road testing is limited by various external factors such as weather, traffic conditions, and test safety, further increasing the difficulty of data acquisition. Therefore, while real-vehicle testing can reflect real interference phenomena, it has significant limitations in terms of the systematic nature, repeatability, and convenience of data acquisition.

[0004] Although millimeter-wave radar interference has attracted industry attention, there is currently no publicly available standardized testing device specifically designed for the acquisition and reproduction of interference signals from vehicle-mounted millimeter-wave radar. Existing testing methods largely rely on the entire vehicle or individual radar units passively waiting for interference events in complex open road environments. There is a lack of an integrated device capable of simulating multi-radar interaction scenarios, controllably generating interference signals, and conveniently acquiring and recording them. This technological gap hinders efficient and reliable data support for interference feature analysis, anti-interference algorithm development, and system verification, thus delaying the practical implementation and optimization of vehicle-mounted radar interference suppression technologies.

[0030] The following specific examples illustrate the implementation of this application. Those skilled in the art can easily understand other advantages and effects of this application from the content disclosed in this specification. This application can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this application. It should be noted that, unless otherwise specified, the following embodiments and features in the embodiments can be combined with each other.

[0031] It should be noted that the illustrations provided in the following embodiments are only schematic representations of the basic concept of this application. Therefore, the drawings only show the components related to this application and are not drawn according to the actual number, shape and size of the components in the actual implementation. In the actual implementation, the form, quantity and proportion of each component can be arbitrarily changed, and the layout of the components may also be more complex.

[0032] The following embodiments of this application provide a radar persistent interference detection device, method and equipment based on alternating transmission, which solves the problems of long acquisition cycle, high acquisition difficulty and high cost in the prior art when collecting interference data.

[0033] The technical solutions in the embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0034] like Figure 1 As shown, this embodiment provides a radar persistent interference detection device based on alternating transmission. The device 100 includes:

[0035] The first bracket 110 is used to fix and install the first jamming radar 111 and the second jamming radar 112.

[0036] The second bracket 120 is used to fix the target detection radar 121; the first bracket 110 and the second bracket 120 are arranged opposite to each other.

[0037] The first jamming radar 111 and the second jamming radar 112 are used to alternately transmit the first frequency modulated continuous wave signal. When the first jamming radar 111 is working, the second jamming radar 112 is in a non-transmitting state, and when the second jamming radar 112 is working, the first jamming radar 111 is in a non-transmitting state. The working timing of the two is synchronized and does not overlap.

[0038] The target detection radar 121 is used to transmit a second frequency-modulated continuous wave signal and receive echo signals within its operating frequency band, so as to collect detection data under the alternating interference of the first jamming radar 111 and the second jamming radar 112.

[0039] This application employs a configuration where a first jamming radar 111 and a second jamming radar 112 alternately transmit a first frequency-modulated continuous wave signal. Specifically, when the first jamming radar 111 is operational, the second jamming radar 112 is in a non-transmitting state (e.g., a dormant state, only powered, not transmitting waves), and vice versa. Their operational timings are synchronized and do not overlap. This alternating cycle ensures that at least one jamming radar transmits a jamming signal at any given time. The target detection radar 121 operates continuously throughout the process, and its received signal is subjected to alternating coverage interference from the first jamming radar 111 and the second jamming radar 112.

[0040] Since the transmission frequency bands (f1 to f2) of the first jamming radar 111 and the second jamming radar 112 completely cover the operating frequency band (f3 to f4) of Radar3, and their alternating transmissions have no time gap, the target detection radar 121 will be unable to obtain an effective echo signal in the normal frequency band, thus achieving continuous jamming of the target. At the same time, each jamming radar is in a heat dissipation state for about 50% of the time, avoiding overheating of the equipment.

[0041] It should be noted that the first jamming radar 111, the second jamming radar 112 and the target detection radar 121 in this application are all millimeter-wave radars, but this application is not limited thereto.

[0042] Figure 2 The diagram shown illustrates a practical application of the radar persistent interference detection device based on alternating transmission described in this application. Figure 2 As shown, the radar continuous jamming detection device based on alternating transmission includes a first bracket (bracket 1) and a second bracket (bracket 2). The first bracket is used to fix and install a first jamming radar (Rader 1) and a second jamming radar (Rader 2); the second bracket is used to fix and install a target detection radar (Rader 3); the first bracket and the second bracket are arranged opposite to each other.

[0043] In this embodiment, the first jamming radar (Rader1), the second jamming radar (Rader2), and the target detection radar (Rader3) are all millimeter-wave radars, and all three radars transmit frequency-modulated continuous waves.

[0044] Considering that continuous emission of millimeter-wave radar can cause it to overheat and crash, this application prepares two jamming radars that emit waves alternately to achieve continuous jamming. The two jamming radars are Radar1 and Radar2, with emission frequency bands from f1 to f2. Radar1 and Radar2 are set to normal working mode, but they are synchronized in timing. When Radar1 emits waves, Radar2 rests, and vice versa.

[0045] One of the jammed radars is Radar3. Radar3 is also in normal operating mode, with the transmission frequency band from f3 to f4. The range from f1 to f2 includes f3 to f4.

[0046] Will Figure 2 In the diagram, bracket 1 (which is an isosceles triangle) and bracket 2 are placed face to face, and Radar1 and Radar2 are mounted on... Figure 2 Radar1 and Radar2 can be used normally once connected to a power source on bracket 1. Radar3 is installed... Figure 2 On bracket 2, Radar3 is connected to a power source and connected to a computer via a debugging interface to collect data.

[0047] The distance between the two supports can be within the radar detection range. During the identification process, the positions of the two supports can be moved, as long as they remain within the radar detection range.

[0048] The distance between the two supports depends on how far the radar can detect, which is related to the radar's radio frequency chip (how far the radar can detect depends on the waveform configuration and antenna energy).

[0049] In one embodiment of this application, the first bracket is an isosceles triangular bracket, and the first jamming radar and the second jamming radar are respectively installed on two sides of the isosceles triangular bracket.

[0050] In one embodiment of this application, the distance between the first bracket and the second bracket is within the detection range of the first jamming radar, the second jamming radar, and the target detection radar, and the distance is adjustable.

[0051] In some embodiments, this application designs the first support as an isosceles triangular support, and installs the first jamming radar and the second jamming radar on the two sides of the isosceles triangular support respectively. The target detection radar is set on the second support. The first support and the second support are placed face to face, and the distance between them can be adjusted, as long as the distance between the first support and the second support is kept within the detection range of the first jamming radar, the second jamming radar, and the target detection radar.

[0052] In one embodiment of this application, the frequency band of the first frequency-modulated continuous wave signal is a first frequency band, the frequency band of the second frequency-modulated continuous wave signal is a second frequency band, and the first frequency band covers the second frequency band.

[0053] In some embodiments, the frequency band range of the first frequency-modulated continuous wave signal includes the frequency band of the second frequency-modulated continuous wave signal. For example, the first frequency band f1 to f2 is 76 GHz to 81 GHz, and the second frequency band f3 to f4 is 76.5 GHz to 77.5 GHz.

[0054] In one embodiment of this application, both the first frequency-modulated continuous wave signal and the second frequency-modulated continuous wave signal are linear frequency-modulated continuous wave signals.

[0055] In some embodiments, the first jamming radar, the second jamming radar, and the target detection radar all transmit frequency-modulated continuous waves.

[0056] Figure 3 The diagram shows the waveforms of the first and second jamming radars described in the embodiments of this application. Figure 4 The image shown is a waveform diagram of the target detection radar described in an embodiment of this application. Figure 3 and 4 As shown, both the first and second frequency-modulated continuous waves use linear frequency-modulated continuous waves, and the corresponding generated signals (i.e., the first frequency-modulated continuous wave signal and the second frequency-modulated continuous wave signal) are linear frequency-modulated continuous wave signals.

[0073] In one embodiment of this application, the target detection radar is further provided with a debugging interface for connecting to an external data processing device to transmit the detection data.

[0074] In some embodiments, after the target detection radar is connected to a power source, it connects to an external data processing device (e.g., an external electronic device) via a debugging interface to collect and transmit detection data.

[0075] The radar interference detection device based on alternating transmission provided in this application is used to simulate a data acquisition scenario under continuous radar interference. By using the radar interference detection device provided in this application to acquire detection data and perform interference identification on the acquired data, this solves the problem that "the randomness of interference phenomena generated by millimeter-wave radar installed on a vehicle during actual driving is relatively large, making data acquisition inconvenient." The above embodiments of this application provide a simple and fast radar interference detection device for data acquisition, which is simple to operate, convenient, fast, and low in cost.

[0076] The working principle of the radar persistent interference detection device based on alternating transmission provided in this application is as follows:

[0077] First, the first jamming radar 111 and the second jamming radar 112 are configured to transmit signals alternately. That is, when the first jamming radar 111 is operating, the second jamming radar 112 is in a non-transmitting state (e.g., sleep state, only powered, not transmitting signals), and when the second jamming radar 112 is operating, the first jamming radar 111 is in a non-transmitting state (e.g., sleep state). Their operating timings are synchronized and do not overlap. This alternating cycle ensures that at least one jamming radar transmits a jamming signal at any given time. The target detection radar 121 operates independently and continuously throughout the process, and its received signal will be subject to alternating coverage interference from the first jamming radar 111 and the second jamming radar 112.

[0078] Next, place the first bracket, which houses the first jamming radar 111 and the second jamming radar 112, and the second bracket, which houses the target detection radar 121, in a specific location, such as a corner of an office or on a desk. As long as the two brackets are facing each other, detection can be performed. The operation is simple, convenient, quick, and low-cost. Then, connect each of the three radars to a power source.

[0079] The target detection radar is connected to the CAN box (CAN bus interface box) via a debugging interface. The other end of the CAN bus interface box is connected to the computer via USB. The CAN box, short for CAN bus interface box, is a communication bridge device between the computer and the CAN bus.

[0080] Open the data acquisition host computer on the computer, collect detection data through the target detection radar, and transmit the detection data to the computer through the CAN bus interface box for subsequent analysis.

[0081] The collected detection data is analyzed using a data parsing program, and the resulting data is used to identify interference with the target detection radar (see [reference]). Figure 5 and Figure 6This invention addresses the problem that "the randomness of interference generated by millimeter-wave radar installed on a vehicle during actual driving is relatively high, making data collection inconvenient." The embodiments described above provide a simple and quick radar interference detection device for data collection, which is easy to operate, convenient, and cost-effective.

[0082] Figure 5 The diagram shown is a schematic representation of the data waveform in the undisturbed state as described in the embodiments of this application. Figure 6 The diagram shown illustrates the data waveform under interference conditions as described in the embodiments of this application. Figure 5-6 As shown, when the data waveform is normal, that is, when there is no fluctuation, it means that the detection data is normal data under undisturbed conditions. If the data waveform fluctuates, it means that the detection data is abnormal data under undisturbed conditions.

[0083] This application utilizes a radar continuous jamming detection device based on alternating transmission for data acquisition. This device can be placed in any convenient location, not necessarily in a moving vehicle, and is easy and quick to operate, facilitating subsequent data jamming analysis. Simultaneously, this application employs a first and second jamming radar that alternately transmit a first frequency-modulated continuous wave signal, with synchronized and non-overlapping operating times. This alternating cycle ensures that at least one jamming radar transmits a jamming signal at any given time. The target detection radar operates continuously throughout the process, its received signal subjected to alternating coverage interference from the first and second jamming radars, preventing the target detection radar from obtaining effective echo signals in the normal frequency band, thus achieving continuous target jamming. Furthermore, each jamming radar spends approximately 50% of its time in a heat dissipation state, preventing overheating.

[0084] This application also provides a radar persistent interference detection method based on alternating transmission. The radar persistent interference detection device based on alternating transmission can implement the radar persistent interference detection method based on alternating transmission described in this application. However, the implementation device of the radar persistent interference detection method based on alternating transmission described in this application includes, but is not limited to, the structure of the radar persistent interference detection device based on alternating transmission listed in this embodiment. All structural modifications and substitutions of the prior art made in accordance with the principles of this application are included within the protection scope of this application.

[0085] like Figure 7 As shown, this embodiment provides a radar persistent interference detection method based on alternating transmission, which is used in the radar persistent interference detection device based on alternating transmission as described above. The method includes the following steps S701 to S703.

[0086] Step S701: Control the first jamming radar and the second jamming radar to alternately transmit the first frequency modulated continuous wave signal, wherein when the first jamming radar is working, the second jamming radar is in a non-transmitting state, and when the second jamming radar is working, the first jamming radar is in a non-transmitting state, and the working timing of the two is synchronized and does not overlap.

[0087] Step S702: Control the target detection radar to transmit a second frequency modulated continuous wave signal and receive the echo signal within its operating frequency band.

[0088] Step S703: In response to the echo signal, control the target detection radar to collect detection data under the alternating interference of the first jamming radar and the second jamming radar.

[0089] In one embodiment of this application, the first bracket is an isosceles triangular bracket, and the first jamming radar and the second jamming radar are respectively installed on two sides of the isosceles triangular bracket.

[0090] The distance between the first support and the second support is within the detection range of the first jamming radar, the second jamming radar, and the target detection radar, and the distance is adjustable.

[0091] In one embodiment of this application, the frequency band of the first frequency-modulated continuous wave signal is a first frequency band, the frequency band of the second frequency-modulated continuous wave signal is a second frequency band, and the first frequency band covers the second frequency band.

Any solution implemented by adding, subtracting, or replacing steps in the prior art based on the principles of this application is included within the scope of protection of this application.

[0108] As described above, the radar persistent interference detection device, method, and apparatus based on alternating transmission described in this application have the following beneficial effects:

[0109] This application provides a radar persistent interference detection device based on alternating transmission, comprising: a first bracket for fixing a first jamming radar and a second jamming radar; a second bracket for fixing a target detection radar; the first and second brackets are arranged opposite to each other; the first and second jamming radars are used to alternately transmit a first frequency-modulated continuous wave signal, wherein when the first jamming radar is working, the second jamming radar is in a non-transmitting state, and when the second jamming radar is working, the first jamming radar is in a non-transmitting state, and their working timing is synchronized and does not overlap; the target detection radar is used to transmit a second frequency-modulated continuous wave signal within its operating frequency band and receive echo signals to collect detection data under the alternating interference of the first and second jamming radars. This application uses the provided radar persistent interference detection device based on alternating transmission for data acquisition. This device can be placed in any convenient location, not necessarily in a moving vehicle, is simple and convenient to operate, and has low cost, facilitating subsequent data interference analysis. It solves the problems of long acquisition cycles, high acquisition difficulty, and high cost in existing technologies when collecting interference data.

[0110] This application employs a system where a first jamming radar and a second jamming radar alternately transmit a first frequency-modulated continuous wave signal, with their operating timing synchronized and non-overlapping. This alternating cycle ensures that at least one jamming radar transmits a jamming signal at any given time. The target detection radar operates continuously throughout the process, its received signal subjected to alternating interference from the first and second jamming radars, preventing it from obtaining effective echo signals in the normal frequency band, thus achieving continuous target jamming. Simultaneously, each jamming radar spends approximately 50% of its time in a heat dissipation state, preventing overheating.

[0111] The descriptions of the processes or structures corresponding to the above figures each have their own emphasis. For parts of a process or structure that are not described in detail, please refer to the relevant descriptions of other processes or structures.

Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this application should still be covered by the claims of this application.
