1. At least one non-transitory computer-readable storage medium having instructions stored thereon that, responsive to execution by at least one computer processor, cause the computer processor to:

  • receive type-specific raw data representing a reflection signal caused by movement of an object within a type-specific radar field, the reflection signal comprising a superposition of reflections of a plurality of points of the object;

    transform the type-specific raw data into a type-agnostic signal representation that is independent of parameters of the type-specific radar field, the transformation according to a model of the object as a set of scattering centers, each of the scattering centers corresponding to one of the points of the object; and

    determine, based on the type-agnostic signal representation, a gesture or action performed by the object.
