The work demonstrates the results of aircraft detection using Sentinel-1 synthetic aperture radar (SAR) images. The resolution of Sentinel-1 images is, in general, insufficient for aircraft monitoring. Nevertheless, the presented examples of processing show that in some cases large airplane types can be detected applying change detection technique. While using change detection methods we need to take into account the problem of detection of objects that are located at the same places in two or several images. This problem was eliminated using a reference image formed by minimum pixels of entire image series. The results of processing in many cases clearly correspond to the number of targets that can be detected in the image manually. The estimated probability of correct detection of an aircraft located in the airfield was about 0.76 using a series of 15 Sentinel-1 SAR images (GRD products) acquired in the same observation conditions within the period from January to November 2017.
