Abstract
Disclosed are methods, systems, and computer-readable medium to perform operations to classifying airfield debris. The operations include generating a series of frequency-modulated chirps having respective frequencies across a frequency range and directed toward a location of an object in an airfield. The operations can include receiving a series of reflections corresponding to a plurality of frequency-modulated chirps in the series of frequency-modulated chirps and generating a two-dimensional frequency-swept spectral signature representing properties of the plurality of received reflections across a frequency range. The operations can include providing the two-dimensional frequency-swept spectral signature as input to a machine learning classifier that is trained to predict characteristics of objects from frequency-swept spectral signatures and receiving an output representing a predicted classification of the object as airfield debris or not airfield debris.
