ABSTRACT:
A band analysis system for determining the optimal signal-to-noise ratio between the spectral emissions from an object of interest and the spectral emissions from background noise for a target detecting and tracking system. Known target and background spectra are applied to a band select system in order to select an initial choice of bands. These bands are then applied to a sensor model system which determines a template for each spectrum. The templates are applied to a noise generation system in order to generate a noise function indicative of the vibrational noise of the sensor and the electronic noise of the system. The noise function also includes a function of the integration time over each band. The noise function and the templates are then used to determine a signal-to-noise ratio based on a weighting function. The signal-to-noise ratio is applied to the band select system and the integration time select system in order to adjust the bands and their integrations time to the optimum value.
