1. A threat detection system comprising:

  • a processor;

    a memory coupled to the processor and having a plurality of image data buffers;

    a display coupled to the processor;

    a plurality of integrated passive sensors coupled to the processor; and

    the processor configured toreceive image data in a format of a plurality of pixels from the plurality of integrated passive sensors operating within at least two spectral bands,store the image data in the plurality of image data buffers, each image data buffer storing the image data of a different spectral band,transmit a synchronized representation of the image data from the plurality of integrated passive sensors to the display,detect relative differences between image contrast values of the plurality of pixels within each image data buffer,assign a particular status as a result of detecting the image contrast values within a portion of the image data exceeding a threshold indicating a probability of a concealed object, andselect an alarm signal to transmit to an alarm based on the particular status defined by the probability of the concealed object.
