A passive magnetic detection and discrimination system and method having at least one sensing structure with a plurality of magnetic inductive sensors arranged on a rigid framework; at least one screening area defined by one or more sensing structures, including a plurality of magnetic inductive sensors structured to respond to a magnetized object passing thereby; and a processor and a memory operatively connected to the plurality of sensors and configured to receive data corresponding to amplitude waveforms created in each of the plurality of sensors by the magnetized object. Based on characteristic waveforms, the system detects and discriminates the magnetized object, alternatively or in addition the system utilizes an artificial intelligence or machine learning module to improve identification of a magnetized object based on the characteristic waveforms created by the magnetized object.

Passive magnetic detection and discrimination for security screening

A radio receiver is made much more immune to jamming signals. A vector EM sensor, in a 2-dimensional (3-axis sensor) or 3-dimensional (6-axis sensor) sensor configuration, is combined with a unique digital rotation to a preferred direction to create a new reference channel and, using an advanced frequency domain noise mitigation algorithm or other noise cancellation algorithm, can effectively reject jamming and other interference signals and improve the signal-to-noise ratio (20-40 dB) and the receiving performance of the receiver. The method can cancel both near-field and far-field interference and improve accuracy for various applications concerned with establishing the direction, or bearing, to a source. A communication receiver with the vector sensor and the cancellation algorithm has unique anti-jamming capabilities even for multiple jamming sources.
