The paper deals with issues of object detection in conditions of smoke, dust curtains and fog in the IR-THz ranges of electromagnetic wavelengths. It is shown that remote detection of objects and determination of their movement direction under conditions of real interference in the atmosphere is provided with high accuracy and reliability in the IR-THz ranges. The results of experimental measurements and the performed calculations show that to reduce the attenuation of the signal received from the object under conditions of smoke, dust curtains and fog, it is necessary to use IR and THz methods together.
