Claim 10:
11. A system comprising:
a first support comprising a magnetic field transmitter configured to generate a first magnetic field;
a second support comprising a plurality of magnetic field receivers including magnetic sensors, the plurality of magnetic field receivers configured to generate samples based on a combination of the first magnetic field and a second magnetic field resulting from interaction of the first magnetic field and an object;
a base plate comprising an inclinometer and being coupled to the first support and the second support; and
at least one data processor configured to at least:
receive data characterizing the samples obtained by the plurality of magnetic field receivers;
determine a distortion component of the samples obtained by the plurality of magnetic field receivers based on signals generated by the inclinometer;
determine motion compensated samples by at least removing, from the samples obtained by the plurality of magnetic field receivers, the distortion component;
classify, using the motion compensated samples, the object as a threat or a non-threat; and
providing the classification.
