PROBLEM TO BE SOLVED: To provide an action detection system capable of detecting the actions of respective targets by discrimination by estimating the position coordinates of respective targets by discrimination even when multiple targets exist within an observation area.SOLUTION: An action detection system associates respective Doppler signals concerning arbitrary targets between respective sensors on the basis of temporal characteristics of Doppler signals of respective targets (step S7), calculates the relative speeds of the respective targets with the respective sensors on the basis of associated respective Doppler signals (step S8), and estimates the positions of the respective targets on the basis of the calculated relative speeds (step S9). |
