Розглянуто задачу знаходження дрібних предметів на фоні навколишнього ландшафту за допомогою радара із синтезованою апертурою. Відправними точками є можливість аналізу в реальному масштабі часу та забезпечення точності, надійності, швидкості оцінки.

Object detection is a very broud process belonging to many very different areas. Among them detection of objects that are lost or hidden in some landscape is the problem of great civil and military importance. Here we combine the nowadays very useful and applicable system, the Synthetic Aperture Radar (SAR) and investigate the possibilities for the object detection using SAR recordings. The starting points are the possibility of real-time analysis (RTA) performed in SAR applications and the very low dependence of the SAR recording on the atmospheric conditions. On the other side, starting points include also the finite resolution of the pictures obtained during recording as well as the finite level of fluctuations, i.e. noise, intrinsically present in the records. Further evaluation of these 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-length are discussed. Such an approach would have a long standing objective of improving airborne instruments used in different purposes and could help in some of situations where processes done should be precise, reliable and fast.
