Abstract: A method of processing a remotely sensed multispectral or hyperspectral image captured in respect of an area of interest including a body of water so as to identify a submerged target, the method comprising obtaining (206), from hydrographic LiDAR measurements, data representative of water depth in respect of said body of water in said area of interest, performing (210) geo-rectification in respect of said hyperspectral image and said water depth data, applying a hydrologic radiative analysis process (211) to said multispectral or hyperspectral image so as to calculate, using said water depth data obtained from said hydrographic LiDAR measurements, data representative of (i) scattered solar radiation and (ii) spectral transmission between a surface of said body of water and a submerged target and subtracting (212) data representative of said scattered solar radiation from said multispectral or hyper spectral image and multiplying a resultant image by data representative of said spectral transmission so as to

Abstract: A method and apparatus for monitoring the movement and activity of targets is provided. The method comprises the steps of initially detecting electromagnetic (EM) radiation reflected by the target and recording spectral information relating to it and detecting EM radiation reflected by a target at a later time and again recording spectral information relating to it. The spectral information relating to the initially detected and later detected targets is then compared, so as to establish whether the initially detected and later detected targets are the same.

Abstract: A system and method are disclosed for detecting a target within a scene. The system comprises a sensor for acquiring hyperspectral image data of the scene, a repository for storing a set of target spectra and a processor for processing spectra generated from locations within the scene with the known set of target spectra. The processor is further arranged to generate a probability that the spectra generated from locations within the scene correspond with one or more target spectra based on the comparison between the spectra generated from locations within the scene with the target spectra.
