Early warning position judgment system and method for vehicle-mounted radar

The invention discloses an early-warning position judgment system and method for a vehicle-mounted radar, and the system comprises a data collection module, a data processing module, an obstacle classification module, an obstacle positioning module and a collision early-warning module which are matched with one another. Filtering, time domain and frequency domain processing is carried out on the collected signals to obtain data with readability and operability, then classification of movable obstacles and immovable obstacles is carried out according to the obstacle classification module, and position and distance confirmation is carried out on the obstacles through the obstacle positioning module; in this way, movable obstacles and immovable obstacles can be effectively classified, and different early warning signals are sent to a driver through the collision early warning module, so that the driver can flexibly take corresponding measures according to the types of the obstacles. And convenience is brought to
