System for processing signal from radar sensor for tracking object by using artificial intelligence and method implementing the same

A radar signal processing (RSP) object tracking system adapted to recognize an object in conjunction with an autonomous driving sensor, the system comprising:

• at least one autonomous driving sensor;
• at least one processor;
• and
• at least one memory storing computer program instructions that, based on being executed by the at least one processor, perform artificial intelligence (AI)-based operations of recognizing an object in a surrounding environment based on multiple point data input from the at least one autonomous driving sensor, the operations comprising:
• obtaining the multiple point data from the at least one autonomous driving sensor;
• performing preprocessing of detection points from the multiple point data to generate preprocessed data;
• performing clustering on the preprocessed data to generate a plurality of clusters each comprising one or more points;
• generating cluster information from each of the plurality of clusters;
• generating a current prediction for a track that has been updated up to a previous time point but has not been updated to the current time point;
• performing association between (i) current time point cluster information among the cluster information and (ii) the current prediction of the track that has been updated up to the previous time point, to generate an association result;
• and
• performing tracking of multiple objects based on the association result.
