Abstract: The present disclosure relates to a system and method for detecting an object abnormality symptom based on a radar micro-Doppler. The system for detecting an object abnormality symptom based on a radar micro-Doppler includes a multiple input multiple output (MIMO) system configured to determine whether an object has a suspicious abnormality symptom by collecting information of the object and a beamforming antenna system configured to form an antenna radiation beam toward the object based on a result of the determination for the object having the suspicious abnormality symptom and to obtain three-dimensional (3D) micro-Doppler information.
