Millimeter-wave imaging of thermal and chemical signatures.

摘要: Development of a passive millimeter-wave (mm-wave) system is described for remotely mapping thermal and chemical signatures process effluents with application to arms control nonproliferation. Because large amount heat usually dissipated in the air or waterway as by-product most weapons mass destruction facilities, remote may be used detect concealed open facilities destruction. We have developed focal-plane mm-wave imaging investigate potential mapping. Results images obtained 160-GHz radiometer are presented different target scenes simulated laboratory. Chemical nuclear identified by measuring molecular airborne molecules emitted from these facilities. filterbank spectral measurements. Proof principle HDO line at 80.6 GHz 4-channel 77-83 radiometer.
