A COUNTING ALGORITHM FOR MULTIPLE OBJECTS USING AN IR-UWB RADAR SYSTEM

In this paper, a counting algorithm is proposed based on the signal's local maximum values of power signals and positions. After background subtraction process to eliminate clutter signals, several positions and values of the signal's local maximum values are searched for some prefixed number of frames. After sufficient values are stored in a buffer, an average of the values is calculated. Among the values, the number of values exceeding the thresholds is counted and stored as 1-st decided targets' number. To improve the performance we vote with some 1-st decided targets' number. We prove this algorithm's performance by some experiments. Simulation results are included experimented in the 6 m by 6 m indoor environment.
