Abstract: A method and apparatus for identifying behavior of a target, and a radar system applied to an automated driving scenario include receiving a radar echo signal from a target, processing the radar echo signal to obtain time-frequency domain data, processing the time-frequency domain data to obtain signal attribute feature data representing a first feature of a radar echo signal attribute and linear prediction coefficient (LPC) feature data representing a second feature of the radar echo signal, inputting the signal attribute feature data and the LPC feature data into a behavior identification model, and outputting behavior information of the target.
