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

Abstract

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.

GNSS‐based passive UAV monitoring: a feasibility study

“…This results in a very unique time–frequency signature that can be used to separate them from other targets. In [33], a general signal model for UAV micro‐Doppler was discussed. Here, the same framework is employed to investigate the feasibility of micro‐Doppler signature extraction using GNSS‐based PBR.…”
