Large scale drought in European part of Russia in 2010 summer caused disastrous forest and peat fires. It revived and intensified research and design works in developing effective instruments for early detection of fireplaces in forest and in peat bog environment which is typical for European Russia. Some of these works are based on experience that is originated from airborne exploration of forest and peat fires in Moscow region in 1972 conducted by authors' institutions. Presented work is aimed in scientific justification of application of airborne microwave complex which should enable early detection of forest and peat fires occurred in Russian forest conditions. To this end we developed model that describes features of fire observations from aircraft or helicopter based on microwave (MW) radiometric measurements in centimeter/decimeter waveband. This model allows us to study features of fire thermal radiation in MW band. As a result we can judge what MW radiometer allows us to detect fire in its early stage when it is covered by vegetation canopy. Based on these conclusions the design recommendations of MW radiometric complex are provided.
