Abstract—In this paper, performance analysis of the object behavior using mmwave radar is proposed. The AWR1642 mmwave radar with frequency 77 GHz that has advantages over the other sensors, especially in penetrate materials and high accuracy, is utilized in this research. The paper presents an analysis of object behavior in the experimental method in the indoor environment. The radar will detect an object by sending a chirp signal and receiving it again after it is reflected. The mmwave radar shows the performances in the distance, number of objects, radiation pattern, and velocity. The measurement results show that the object can be detected up to 3 m in the indoor environment with a high level of accuracy and stability. Then, the radar can detect multiple objects in the Line-of-Sight (LOS) condition, where the received power level would be attenuated by about 10 dB after penetrating the first object. The research results showed the beamwidth of the radar is 140 degrees with a directional radiation pattern from 20 degrees to 160 degrees. In this system, radar has been able to identify the velocity of the object accurately. It appears that increasing the speed will affect the Central Processing Unit (CPU) usage on the radar too. The proposed system showed excellent performance in object behavior analysis, and it can be utilized in Synthetic Aperture Radar (SAR) applications.
