<title>Advanced Infrared Sensors And Radar Systems For Tactical Target Acquisition</title>

Abstract

Current Army tactics are placing greater emphasis on extended engagement ranges and improved adverse visibility performance. Two candidates for providing enhanced capability, in these areas, are (1) the far infrared high density focal plane technology and (2) the millimeter wave technology. The Army is currently exploiting both of these technologies for providing an improved target acquisition capability. Recent technical advances in infrared detector materials and focal plane signal processing have provided the impetus for high performance infrared imaging systems. Focal plane array candidates are available in both hybrid and monolithic structures which can provide single line video outputs. Charge coupled device technology is used extensively in these arrays to provide on-focal-plane time-delay-and-integration (TDI), multiplexing, and signal conditioning functions. Image processing research has evolved to the stage where implementation is feasible both on and off the focal plane. Recent advances in solid state millimeter wave devices have made it practical to consider multispectral tactical systems. Millimeter wave radars can provide an enhanced target acquisition capability and tracking to augment current infrared devices under heavy smoke or fog conditions. A millimeter wave system, using state-of-the-art signal processing can provide adequate resolution for both target detection and tracking using moderate antenna apertures. This paper will discuss current ongoing Army efforts in these technologies, their synergism, and effective utilization in tactical application.© (1977) COPYRIGHT SPIE--The International Society for Optical Engineering.
