The wide circle of urgent ecological and economical problems includes one problem that is especially important for oil and gasproducing countries on whose territories trunk pipelines run. The timely detec tion of small leaks and their elimination helps to prevent large accidents, which are very harmful to the environment and lead to tremendous losses. The urgency of this problem is also confirmed by the fact that in order to test European gas pipelines the first rank European distributors of natural gas together with two European space agencies have created a consortium for the purpose of developing a satellite equipped with appropriate instruments and putting it in orbit. An infrared (IR) spectral radiometric device for probing gas main pipelines and detecting gas leaks is described. The engineering description and the operating principle of a universal IR spectroradiometer mounted in a helicopter are presented. IR scanning of pipelines was performed in the wavelength range 8-12 micron by a helicopter flying along the routes of pipelines. The technique for measuring IR fluxes from extended heat sources is also presented.
