A detection and tracking system based on MIMO Doppler radar sensor

We describe a system that can track a moving object in the range of 40 meters by using two MIMO Doppler radar sensors. Due to the low computing capability of the sensor node, it is impossible to exactly determine the target´s position. So we divide the sensing range into 4 10-meter long sections and develop a real-time tracking algorithm called Advanced Tracking Algorithm for Doppler Radar Sensors (ATAD) to point out which section the moving target is in. The algorithm automatically determines the threshold for detection at the initial period, adjusts this value during running time, and determines the relative location of the target in real-time.
