<p> 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. </p>

“…The concept of using 5G signals as an illumination source is a new one, still at the feasibility study and demonstrator level -far from the finished product [15], [22]. The 5G illuminator signal structure requires further research on its characteristics and structures to confirm that this illumination can be used in future for passive radar technology [23]. This paper proposes a novel approach to the processing which has been validated using simulated signals as well as real measurements performed in an operational 5G network.…”

This paper presents an alternative processing chain for the passive radar using fifth-generation (5G) standard technology for broadband cellular networks as illuminators of opportunity. The proposition is to use a 5G synchronization signal block's (SSB) periodically transmitted modulated pulse in 5G-based passive coherent location (PCL) system processing. Although the SSB periodicity limits the velocity ambiguity, the paper describes a solution to tackle this problem in a single target scenario. The method is advantageous when there is a lack of transmission in the telecommunication channel, and the 5G SSB is the only existing signal. The paper proposes a signal processing pipeline for 5G-based PCL that is inspired by passive radars using non-cooperative pulse radar as an illumination source. The method has been validated using simulated and real-life 5G data measurements. The results presented in the paper show the possibility of detecting a moving target with a lack of data transmission in the 5G network, using only the SSB when the classical passive radar signal processing fails. The presented results prove the possibility for a significant increase of 5G network-based PCL utilization in short-range applications.
