Obstacle Avoidance onboard MAVs using a FMCW RADAR [article]

Nikhil Wessendorp, Raoul Dinaux, Julien Dupeyroux, Guido de Croon
2021 arXiv   pre-print
While extensively used in autonomous driving, miniature FMCW radars on MAVs have been relatively unexplored.  ...  the potential for the sensor to provide a more robust sense and avoid function in fully autonomous MAVs.  ...  that the FMCW radar can reliably detect obstacles and determine when a collision is imminent, thus allowing the MAV to safely avoid damage or injury to the MAV or environment.  ...

Evolved neuromorphic radar-based altitude controller for an autonomous open-source blimp [article]

Marina González-Álvarez, Julien Dupeyroux, Federico Corradi, Guido de Croon
2022 arXiv   pre-print
In this paper, we propose an evolved altitude controller based on an SNN for a robotic airship which relies solely on the sensory feedback provided by an airborne radar.  ...  By mimicking the biological process for transferring information between neurons using spikes or impulses, spiking neural networks (SNNs) allow for low power consumption and asynchronous event-driven processing  ...  Finally, a fast chirp frequency-modulated continuous wave (FMCW) radar module from Infineon with a resolution of ±20 cm is used as a ranging sensor for the closed-loop control.  ...

Radar-based detection and identification for miniature air vehicles

Allistair Moses, Matthew J. Rutherford, Kimon P. Valavanis
2011 2011 IEEE International Conference on Control Applications (CCA)  
By contrast, this paper describes the design of a light weight, X-Band (10.5GHz) radar system for use on a small-scale (< 25 kg) rotorcraft.  ...  in a laboratory setting.  ...  Furthermore, the overall reaction time is decreased by the use of Doppler mode since a target's presence and velocity can be acquired from a single sample window, whereas FMCW must use multiple sample  ...
