“…As a case study, the Aveillant Gamekeeper 16U is used with the chosen parameters being summarised in Table I. Most of the parameters have been drown from [17]- [19] while others have been fixed to offer a maximum detectable range of approximately 5km [18]. The transmitter gain is calculated as G T = 10 log 10 N T , where N T = 8 is the number of transmitting elements [19].…”

Unarmed Aerial Vehicle (UAV) systems are very challenging targets due to their small size and ability to fly in low altitudes and speed. Particularly, in radar systems UAVs can exhibit similar radar cross section and Doppler parameters to clutter returns such as birds and trees. For this reason, often the micro-Doppler signature of the detected target is employed as discriminative characteristic. This work aims to examine micro-Doppler jamming solutions that could be implemented on board of miniature UAV platforms in order to deploy electronic countermeasures to radar sensors, with the aim to provide useful information to the radar community to counter these.

“…Radarbased detection represents a significant direction of the current research and development works. A number of papers present specially developed system architectures that are capable of detecting small-sized UAVs [1]. Stephen Harman in [2] made efforts to examine the Doppler signature and estimate the RCS variation of the rotating propellers on multi-rotor UAVs.…”

“…Beyond detection, distinction from other flying objects (e.g., birds) and the classification of such devices is of great importance. In [1], measurements are shown regarding the Doppler characteristics of small sized UAVs investigated in the L-band. In their results, reflection from the rotating propellers can be clearly identified.…”

Electromagnetic scattering from propellers of smallsized Unmanned Aerial Vehicles (UAVs) is studied in this work. Previous works have shown that rotating propeller blades produce significant fluctuations of the Radar Cross Section (RCS) in the case when the propeller length is about half a wavelength of the illuminating wave. To some extent, this facilitates both the measurement of the RCS in anechoic chamber and the detection of small-sized UAVs. In the present contribution, these studies are extended to the case of multiple propellers, between which an electromagnetic coupling is expected. The scattered field and the RCS is calculated by means of electromagnetic simulation using an integral equation formulation, and the theory is validated against anechoic chamber measurements.
