Sažetak
The Search and Rescue (SAR) mission, a set of procedures for airplane and/or other accident location precise determination, is officially recommended by International Civil Aviation Organisation. The search part is conducted in various ways, all of which have characteristic duration, equipment involved, expenses, and quantitative measure of success. Among the characteristics, the search part duration minimisation is a permanent task. Although in many cases in searching the survival beacon signal, originating from the accident location, is used, in a general case the searching should be performable without any precise information about the accident place location. The reasons for this occur even when the survival beacons are present because they could fail to work properly, or could be separated and dislocated from the majority of accident remainings. In this article it is argued that incorporation of the synthetic aperture (SA) radar in the SAR mission enables the mission improvement. The crucial properties of the SA radar it brings into the SAR missions is the complete mission independence on survival beacons, and its all-day all-weather capability. Therefore, the process of searching can be performed much faster and SAR mission made more efficient. The possibility of using the SA radar for fast and precise localization of places of small objects is mathematically modelled. The existing models for generation of the realistic vegetation layer and soil configuration properties are used in a combination with the representative small object models. Using modelling, the realistic SA radar images are generated and analysed from the point of view of the object image extraction.
