Abstract:
1. A detection system comprising: a forward looking infrared receiver that is operable to produce a first electrical signal indicative of thermal energy radiated by an improvised explosive device, the forward looking infrared receiver having a field of view with a first axis; a plurality of radio frequency receivers that are coupled to a corresponding plurality of directional antennas and operable to produce a plurality of second electrical signals indicative of electro-magnetic energy emitted by the improvised explosive device, each of the plurality of directional antennas having a field pattern with a second axis that is aligned at a specified angular orientation relative to each other and to the first axis; and a signal processing circuit coupled to the thermal imaging camera and the plurality of radio frequency receivers, the signal processing circuit being operable to:
