A dual-band infrared sensor package for use in radar system applications is provided. The package includes two detector arrays, an InSb photodiode array sensitive in the mid-wave infrared radiation range and a HgCdTe photodiode array sensitive in the long-wave infrared radiation range. The package further includes integrated circuits which provide electrical control to and data output from the detector arrays. A three dimensional arrangement of the detector arrays, integrated circuits, and ceramic interconnecting substrates is used to provide a relatively small sensor package suitable for radar system applications so that radar signals are not obscured. |
