Antenna-coupled microbolometer millimeter-wave focal plane array technology

摘要: To develop a useful, low cost, passive millimeter wave imaging system through batch processing of an integrated 2D antenna-coupled microbolometer focal plane array. achieve high array sensitivity sampling and post detection signal techniques adapted to this type A review will be given the thermal bridge bolometer combination that is being developed, rationale for choosing materials making up bridge. The material bias circuitry noise power consumption discussed. An antenna design also Each receiver must satisfy multiple requirements. It have large RF bandwidth, match feed from system, allow close packing on plane. overall geometry provide convenient vacuum environment bridges along with ready access ROIC signals. approach taken overview geometry, strategy, maximizing video dynamic platform.
