A Survey on Radar Techniques for Detection,Tracking, and Classification
of Aerial Threats
Abstract
The use of unmanned aerial vehicles (UAVs) for different applications
has increased many folds in recent years. The UAVs are expected to
change the future air operations. However, there are instances where the
UAVs can be used for malicious purposes. The detection, tracking, and
classification of UAVs is challenging compared to manned aerial vehicles
(MAVs) mainly due to small size, complex shapes, and ability to fly
close to the terrain and in autonomous flight patterns in swarms. In
this survey, we will discuss current and future aerial threats, and
provide an overview of radar systems to counter such threats. We also
study the performance parameters of radar systems for the detection,
tracking, and classification of UAVs compared to MAVs. Finally,
limitations of radar systems and comparison with other techniques that
do not rely on radars for detection, tracking, and classification of
aerial threats are also provided.
