“…The bandwidth and the signal power (or range) are exchangeable due to the dependence of both on the PW. Ultra-wideband (UWB) radars are popular due to their large bandwidth (high range resolution) [40]. The multipath components from a UWB radar can be resolved in the order of centimeters, therefore, fine details of the aerial vehicle or image can be obtained.…”

<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>

“…M-sequence), stepped frequency, pulse compression, random noise, and other signal formats that have high effective bandwidths [20]. UWB technology in radar allows for a very high accuracy ranging, rigidity to multi-path propagation and external EMI [26]. With regard to these properties, UWB radars have become very popular for military, rescue, automotive, and medical applications as well as for material characterization in recent years.…”

In this paper, imaging method for moving target tracking by a multistatic ultra-wideband radar system is described. The task of moving target tracking consists in estimation of a target trajectory based on processing of raw radar data obtained from all receiving channels of a radar system. Then, the imaging method applied for target tracking consists of such signal processing phases as raw radar data pre-processing, background subtraction, fusion of the data obtained by receiving antennas of a radar, detection, localization and tracking itself. The performance of the imaging method described in this paper is demonstrated by signal processing obtained by M-sequence UWB radar for a scenario represented by through wall tracking of a single moving target. The obtained results confirm the excellent performance of the discussed method.
