In-cabin occupancy detection has become increasingly important due to incidents involving children left in vehicles under extreme temperature conditions. Frequency modulated continuous wave (FMCW) radars are widely used for non-contact monitoring and

Abstract A robust method for ultra‐wideband (UWB) imaging of buried shallow objects based on time gating, Wiener filtering, as well as constant false alarm rate (CFAR) is proposed. Moreover, it is demonstrated that Wiener filtering can be used as a

The detection of targets under the ground is an important procedure that is typically performed by a human non-automatically. Recent studies have automated this process using artificial intelligence (AI) based on radar images. There are three main st

Imaging algorithms can make the detection of buried objects easier. These algorithms use reflected power from different scatterers with different time delays. Reflected signals from almost perpendicular angles have a significant weight in the imaging

The backscatter signal analysis, as the landmine material could vary, has to be as much advanced as possible. One major problem with the conventional methods is that they are not able to detect new plastic landmines. In the recent research, the class
