Electro-optical and radar technologies are being merged in the form of coherent infrared radars. In this paper we discuss the potential military applications of these devices. We begin by reviewing the factors favoring coherent infrared radars over alternatives such as conventional radars or electro-optical sensors. These include increased resolution, adequate weather penetration, and signature stability. Next we outline the military applications of existing sensors and indicate those applications where coherent infrared radars offer the potential of improved performance. Finally, the state-of-the-art in coherent infrared radar technology is indicated by a brief summary of several current development programs.
