Experimental results of DVB-T2 passive coherent location radar

Toward 3D passive radar exploiting DVB-T2 transmitters of opportunity

“…The detection capabilities were investigated during experimental campaign under different scenarios [15]. The detection ranges are represented in Table 2 by equivalent monostatic values obtained for the effective radiated power of 5 kW and signal-to-noise ratio (SNR) of 13 dB under the assumption that the receiver and transmitter are allocated at the same position.…”

“…The detection and recognition of drones is a challenging task for the radar due to their small size, low radar cross-section, ability to fly slowly at low altitudes. Despite this, the 2D passive radar exploiting DVB-T2 transmitters for illumination demonstrate good performance for drone detection [15]. In order to estimate and prevent a potential risk of drone collision with aircrafts, or its use for terrorist attacks, espionage activities, and others, it is important to have information about the target altitude.…”

Simulation and Detection Performance Evaluation of a UAV-mounted Passive Radar

“…• Global Navigation Satellite Systems (GNSS) [6] • Wi-Fi [7] • Digital Video Broadcasting-Terrestrial (DVB-T(2)) [8], [9] • Global System for Mobile communications (GSM) [10] and Long-Term Evolution (LTE) [11], [12], GNSS-based techniques have some advantages since the signals are available globally and they do not interfere as in cellular type systems. Theoretical range resolution is about 15 m, but due to the low signal strength, the detected target should have large radar cross-section (RCS) (about 50 m 2 [6]), which is not the case for a typical UAV.…”
