This technical note describes the design of a tactical near-all- weather infrared airborne radar IRAR. The requirements for this radar include both 1 wide field MTI search for target detection against a cluttered terrain background and 2 narrow field high angular resolution imagery for target recognition and identification. The principal new technology issues identified and techniques proposed include a heterodyne detection antennareceiver in an array configuration, compact Maksutov-Cassegrain telescope optics design, MTI pulse integration signal processing, and real time image processing for speckle and glint reduction. Expected weather penetration capability for this radar is assessed with the aid of a recent analysis of real weather data from a number of locations in Central Europe.
