Abstract
A range/intensity mapping algorithm suitable for displaying active infrared radar images in real-time using pseudocolor is discussed. The availability of range as well as intensity in an active system requires the development of a multidimensional signal processing technique. The high resolution of an optical imaging system combined with conventional radar techniques provide a unique real-time image unattainable using microwave radar. By mapping range information into hues and intensity information. into different apparent brightness levels of each hue, a three-dimensional quality can be imparted to infrared imagery. Examples of its implementation, using data generated by an infrared radar testbed system, are given. Finally, a potential hardware implementation of this technique is described.
