1. A method for generating and displaying an image of a target object, including the steps of:
- receiving an infrared signal from an infrared sensor that is positioned to detect the target object;
receiving a radar signal from a radar sensor that is positioned to detect the target object;
processing the infrared signal to extract information concerning an interior portion of the target object, and generating a processed infrared signal representative of this extracted information;
processing the radar signal to extract information concerning the size and shape of the target object, and generating a processed radar signal representative of this extracted information;
generating a first wavelet transform by transforming the processed infrared signal into a wavelet domain;
generating a second wavelet transform by transforming the processed radar signal into the wavelet domain;
combining the first and second wavelet transforms to produce a combined wavelet signal;
inverse transforming the combined wavelet signal to produce an image; and
,displaying the image.
