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.
