Range-Doppler, Target-Referencing Imaging Systems (RD-TRIMS)

Abstract

RD-TRIMS (Range-Doppler Target-Referencing, Optical-Imaging Systems) is a new imaging concept that enjoys pulsed, visible laser illumination. It differs from conventional microwave and infrared range-Doppler (RD) imaging radars in that the return wave is self-referenced rather than referenced to a local oscillator. This results in enormously reduced coherence requirements for the source and permits visible Doppler systems to be implemented, with the advantage of increased reflectivity, resolution, and illumination efficiency. In this program, analytic and computer models of an RD-TRIMS system were developed to explore the feasibility of the proposed concept. For the simple models we investigated, excellent images and signature information were obtainable.
