Problems solved by technology
However, with the development of information technology, the sampling rate of chip data has increased rapidly. With the help of high-sampling rate radio frequency storage and forwarding technology, hackers can copy and store the electromagnetic waves emitted by millimeter-wave radar, and quickly "clone" extremely similar False target echo signals, for this kind of man-made intentional interference, the existing radar anti-jamming methods are powerless
[0004] With the help of high-sampling-rate RF store-and-forward technology, rapid and "highly cloned" interference patterns such as "multi-interference source synchronous forwarding angle deception", "delay forwarding distance deception" and "frequency shift forwarding speed deception" are generated, resulting in In complex traffic scenes, the radar output target list has disadvantages and hidden dangers such as increased false alarm rate. Once hackers use the above-mentioned technical means to carry out "injection" electromagnetic soft attack on millimeter radar, it will seriously affect the "smart car based on millimeter wave radar". " driving safety will further cause social panic and affect the credibility and substantive implementation of smart cars

Embodiment Construction
[0031] Such as Figures 1 to 3 Shown, a kind of smart car millimeter-wave radar anti-hacking jammer attack device, comprising:
[0032] The radar interface module is used to complete the real-time reading of the radar target measurement data of the vehicle;
[0033] The radar networking interface module is used to complete real-time reading of target measurement data of other networking radars in the scene;
[0034] The distance-speed correlation module is used to calculate whether the "distance change rate" and "measurement speed" of the vehicle's radar measurement target match. If the distance change rate of a certain target does not match the speed, it is judged as a false interference target;
[0035] The target fusion module is used to fuse different radar measurement target parameters, that is, for the same target in the scene, the measurement results of each radar are extracted and summarized;
[0036] The distance correlation module is used to convert the "distance m...

Description
technical field [0001] The invention relates to the fields of intelligent transportation and intelligent automobiles, and relates to an intelligent automobile millimeter-wave radar anti-"hacker jammer" attack device. Background technique [0002] For a long time, in the field of smart cars and smart transportation security, researchers have mainly focused on and studied related issues centered on "network security", that is, to study and prevent hackers from attacking smart networks. However, in addition to the above-mentioned "network security" , For smart cars, the security issue of millimeter-wave radar has been neglected for a long time. Preventing hackers from interfering with millimeter-wave radar should be an area that has attracted great attention. [0003] When the existing smart car millimeter-wave radar detects and measures the target in the traffic scene, it is judged whether the target is detected by "whether the target echo energy is greater than the sensitivit...
