Ferromagnetic detector and threat analysis

A system for detecting ferromagnetic objects and analyzing the threat of said objects becoming projectiles as they pass through a passageway, the system comprising:

• a first sensor array comprising one or more magnetic field sensors configured to secure to one or more portions of the passageway, wherein the first sensor array is configured to:
• generate a first signal in response to detecting a magnetic field indicating the presence of a ferromagnetic object in proximity to the first sensor array;
• and
• output said first signal;
• a second sensor group configured to secure to a portion of the passageway, and wherein the second sensor group is further configured to:
• generate a second signal in response to an object moving relative to the passageway and in proximity to the passageway;
• and
• output said second signal, wherein said second signal comprises information relating to a velocity of the object and a direction of motion of the object relative to the first sensor array;
• and
• a processor in communication with the first sensor array and second sensor group, the processor configured to:
• receive the first signal from the first sensor array;
• determine a magnitude of the first signal;
• receive the second signal from the second sensor group;
• determine the velocity of the object relative to the passageway and the direction of motion of the object relative to the passageway;
• and
• generate an alert indicating a threat level of the object passing through the passageway, wherein the threat level is based, at least in part, on the magnitude of the first signal, the velocity of the object and the direction of motion of the object.
