American scientists from Ohio State University have proposed a new way to detect forest fires using synthetic aperture radar (SAR). It allows you to remotely analyze the situation of the region in any weather conditions and time of day. The study was published on: Web site American Geophysical Union (AGU).
Synthetic aperture radars use many small antennas or perform many soundings, changing their positions and then combining the radar results into a single image; as if the research were carried out by a single installation with a large antenna. This method allows you to accurately measure the geophysical, hydrological and meteorological characteristics of the region.
Unlike laser radars and other optical systems, SARs work day and night, in cloudy conditions, and can also “see” through smoke, which is important in wildfire conditions.
Scientists noted that SAR has great potential to detect forest fires and monitor their life cycle and consequences. This will help identify fire-prone areas by analyzing moisture levels and identifying the types of vegetation found there.
The team hopes to use the data to create their own wildfire prediction algorithms.
Previously in Russia was created Drone with ground-penetrating radar to search for mines from the air.
