Description
Technical Field
[0001] The present invention relates to the field of radar detection technology, and in particular to an intelligent collision detection method and system. Background Art
[0002] The field of radar detection technology covers the use of radar systems to detect and analyze objects in the environment. It has been developed from the military field and is widely used in civil fields such as aviation, maritime and traffic safety. Radar systems can determine the position, speed and characteristics of objects by emitting electromagnetic waves and receiving reflected waves. In modern applications, radar detection technology has evolved to achieve high-precision distance measurement and speed perception. It is an indispensable part of intelligent systems such as autonomous vehicles and collision warning systems. Radar technology is particularly suitable for external monitoring and warning systems due to its ability to work reliably in all weather conditions.
[0003] Among them, an intelligent collision detection method refers to the use of a radar system to continuously monitor obstacles in front of or around the vehicle, analyze potential collision risks in real time, and automatically take preventive measures such as adjusting the vehicle speed or issuing warnings to avoid or mitigate collisions. Its purpose is to enhance vehicle safety, reduce traffic accidents, and improve the protection level of drivers and passengers, especially at high speeds or in complex traffic environments.
[0004] Although existing radar detection technology has been widely used in military and civilian fields, it has problems with insufficient response speed and accuracy when processing real-time data in highly dynamic and complex environments. Existing technologies cannot effectively adapt to emergencies in rapidly changing traffic environments, especially in multi-target tracking and dynamic path prediction, resulting in delayed response or false alarms in the early warning system. Existing systems lack sufficient flexibility in radar coverage and signal optimization, and cannot adjust emission angles or scanning parameters according to real-time conditions. Technical limitations are particularly evident at high speeds or in severe weather conditions, resulting in reduced system performance and affecting overall safety assurance capabilities. The lack of a highly adaptive collision prevention mechanism is the main shortcoming of existing technologies in improving driving safety. In actual applications, it results in insufficient or inaccurate responses to potential dangers, and is unable to effectively prevent accidents. Summary of the invention
