Abstract-The capability of using illuminators of opportunity for target classification is of great interest to the radar community. In particular the alternative use of Global Navigation Satellite System (GNSS) has recently initiated a number of studies that aim to exploit this source of illumination for passive radar. We recently introduced the concept of a GNSS based passive radar for extraction of micro-Doppler signatures from helicopter rotor blades with the aim of identify these kind of targets. In this paper we present the experimental validation of our concept with real data from two different models of helicopter.

Passive Forward-Scattering Radar Using Digital Video Broadcasting Satellite Signal for Drone Detection

“…Many passive FSR approaches, other than DVB-S-based, addressed issues on airborne targets such as RCS verification of different aircraft in [19], detection and classification of helicopters in [20], a feasibility for PFSR implementation in [21][22][23]. Signal characterization and optimization was also presented in [24,25] to improve the detectability of airborne targets.…”

Understanding the potential of Self-Protection Jamming on board of miniature UAVs

“…As it can be seen in (8), the time delay is modelled slowtime. Additionally, no Doppler shift is accounted in the fast time as the target is not expected to noticeably change its location during the period of a single pulse [16].…”

“…Those secondary motions are generally periodical and introduce secondary Doppler components generally referred to as micro-Doppler effect [5]. Micro-Doppler has been widely used for classification in a variety of targets including ballistic and helicopter targets [6]- [8]. Through the last years, different techniques and system configurations exploiting micro-Doppler have been proposed in the literature for Drone detection and classification [2].…”

GNSS‐based passive UAV monitoring: a feasibility study

“…Furthermore, depending on the relative distance between the transmitter and receiver, radar systems can be categorised as monostatic or bistatic. In recent years, passive bistatic radar (PBR) systems have been widely suggested for a variety of applications [2–11]. While having more limitations compared to their active counterparts, PBR systems offer an attractive monitoring solution especially for low cost and low size, weight and power (SWaP) applications as they exhibit lower manufacturing and operational cost as well as SWaP requirements due to the lack of emitting elements.…”
