Recent development of monolithic millimeter -wave integ rated circuit s ( MMIC) technolo gy has led to the employment o f focal plane arr ay receivers in passive millimeter-w av e imag ing sy stems. We describe ty pical focal plane array receivers, and make a further analysis on the performance o f bo th mixer and dir ect detect ion radiomet ric receiver. T he IF amplification of the former is easier to achieve, w hile the sensit ivity of the lat ter is bet ter . T he sig nal-to-noise rat io characteristics o f focal plane array imag ing sy stem are also discussed in details. T he r esult s w ill benef it design consider ations and perfo rmance evaluat ions of mill imeter- wave focal plane ar ray imaging system.
