“…In recent years, algorithms based on machine learning have been used to detect faults in machine functioning and control [50][51][52][53][54][55][56][57][58]. First, acoustic measurements were performed in an anechoic chamber and then these were analyzed to characterize the phenomenon [59][60][61][62][63][64][65]. An appropriate number of observations were then extracted, and these data were pre-processed.…”

“…Here, an active imaging device with a very narrow field of view could counter these challenges and could be used to gate out the background, increase resolution and signal-to-noise ratio, and be independent from lighting conditions. Our team has access to a shortwave-infrared laser gated-viewing system as presented by Christnacher et al 10 In the near future, we will perform tests to investigate the pose estimation approach in operational conditions. Lighting conditions and observing MUAV flight behavior at a larger range can reduce the ranging accuracy of the proposed pose estimation approach due to an expected smaller scaling effect of the MUAV with the range at narrower observation angles.…”

“…Detection and tracking of MUAVs have been studied using single millimeter-wave RADAR, 8 optical (VIS/SWIR) 9 sensors or within a multisensor approach using passive/active imaging, acoustics, and RADAR in various field trials. [10][11][12][13] Further, classification of MUAV has been investigated using image-based deep-learning and high-level data-fusion approaches. [14][15][16] Classification can also be used to distinguish MUAVs from, e.g., birds.…”

“…To increase UAV detection reliability, in [9], algorithms-based template matching and morphological filtering were adopted to improve the ability to recognize UAV within a wide range of relative distances. In Reference [10], acoustic and optical detectors were combined to improve UAV detection and tracking through active imaging.…”
