Description
Summary:For many years, Passive radar have been studied and their capability for enabling target detections at low altitude is now quite well known. Since a couple of years, recent works began to experiment UAV detection by using DVB-T passive component [1], [2], [3], [4] or Wi-Fi illuminator [5], [6]. In this article, we are presenting some experimental results about UAV detection with DVB-T illuminator. According to the configuration, the UAV may be detected directly (due to UAV main body kinematic), by its blade modulation [7] or by both. The last section of this paper will analyze the blade modulation fluctuations according to the UAV trajectory in order to illustrate one potential benefit of such a 'blade modulation detection'.
