Investigation of UAV Detection by Different Solid-State Marine Radars

Abstract

The development of unmanned aerial vehicle (UAV) technologies provides not only benefits but also threats. UAV technologies are developing faster than means of detecting and neutralizing them. Radar technology is one of the means of UAV detection which provides the longest detection range. Today’s market provides low-cost solid-state marine radar working on FMCW and pulse-compression principles of operation. Despite such radars having attractive features, they were not designed for UAV detection. Although they are not optimal, they could be used for UAV detection. The detection possibility of UAVs by marine radars was investigated by using three types of radars and two types of small UAVs as targets. Radar cross-section measurements of the targets were made in laboratory conditions.

Exploring Radar Micro-Doppler Signatures for Recognition of Drone Types

“…Drones are known to produce micro-Doppler shifts in radar echoes due to the modulation of incident radar waves by their rotating blades [13]. These shifts are unique radar signatures that can aid in the detection and classification of drones from other clutter, such as birds and humans [14][15][16][17][18][19][20]. Drones can be classified into three types based on the relative direction between the rotating plane of blades and the ground plane.…”

FPGA-Based Pulse Compressor for Ultra Low Latency Visible Light Communications

“…Chirp coding and pulse compression represents a well-known technique for transmitting and recovering the data from noisy signals. Chirp coding has been developed especially in radar and applied for improving its penetration [18], but it is now exploited in many other fields like, for example, biomedical investigations [19] or sonar [20].…”
