1. A computer-implemented method comprising:

  • obtaining, by a transceiver, multiple radar signals, each radar signal associated with a frequency;

    generating, by a processor, a representation of a space that comprises a barrier that defines an interior region and an object in the interior region, the generated representation being based on a known location and orientation of the barrier relative to the object;

    determining, by the processor and using the generated representation, a modeled parameter that defines reflections by the object of a radar signal that propagates through the barrier and into the interior region and irradiates at least a portion of the barrier and at least a portion of the object;

    accessing, by the processor, a parameter of a candidate detection of the object, wherein the parameter of the candidate detection is determined from the multiple radar signals received by the transceiver;

    comparing, by the processor, the modeled parameter that defines the reflections by the object of the radar signal to the accessed parameter of the candidate detection; and

    classifying, by the processor, the candidate detection as an actual detection or a false alarm based on the comparison.
