Abstract
A method and apparatus for separating or extracting a desired multispectral optical signal of interest from a background. Radiation is detected from a scene which includes the multispectral optical signal of interest and the background. A multiplicity of wavelength bands are selected from the detected radiation to generate a multispectral input spectrum. The multispectral input spectrum is processed to separate the multispectral optical signal of interest from the background.
