Sažetak
The object detection is a rather general process often performed in the field of landscape remote sensing. The possibility of detection of objects that are lost in some area is of great importance for enabling more reliable modern communications through elimination of consequences of possible failures. Here we discuss the possibility of small object detection using the Synthetic Aperture Radar (SAR). Starting points are the possibilities of real-time analysis (RTA) performed in SAR applications, low dependence of results obtained on the atmospheric conditions as well as a finite resolution of the pictures obtained during recording and a finite level of fluctuations, i.e. noise, intrinsically present in the records. Further evaluation of this properties is done using physical properties of matter-radar wave interaction and the radar signal processing (RSP). The interplay among the characteristic distances of an object that is looked for, the surrounding vegetation or other forms in landscape and the radar wave wavelength is discussed.
