Dual Colour MAWS system operates in the mid IR band for identifying the approaching missiles of all generations. The spectral information of two colors is used to discriminate efficiently between sunlight reflections, background radiation and the radiation from the missile. The DCMAWS consists of a set of up to six dual color IR sensors installed on the platform, which samples the space in accordance with the defined spatial coverage and integrated with advanced processor running state-of-the-art clutter rejection and tracking algorithms to declare the oncoming missile threat with a very good false alarm rate.
