Abstract: IR plume detection is employed in missile warning systems (MWS). Multinational cooperation with significant capital is invested in the development of two major Infra-Red (IR) based plume detection alternatives, single-color IR (SCIR) and dual-color IR (DCIR). IR natural clutter especially solar reflections cause significant false alarm rate. SCIR uses state-of-the-art technology and sophisticated algorithms to filter out threats from clutter. On the other hand, DCIR are aiming at using additional spectral band measurements, to allow the implementation of a robust approach for performing efficiently the plume detection.
We present the results of a thorough study that we conducted for exploiting the added value of the additional data available from the second spectral band. Here we consider the CO2 emission bands as well as off peak band that is used as a guard. The innovative filter that we propose is based on the properties of the Surface Plasmon Resonance (SPR) of nanorods. Using visible photons to change the sample resonance condition we affect the IR transmission parameters within microseconds.ere we consider the two CO2 The findings of this study refer also to missile warning systems efficacy, in terms of operational added value.
