“…W dostępnych publikacjach naukowych dotyczących omawianego zagadnienia przedstawiane są elementy strategii unikania kolizji z różnymi przeszkodami [8]. Rozważane są sposoby określenia wykrycia zagrożenia kolizji [1,6] oraz metody sterowania manewrami omijania przeszkód dla wybranych scenariuszy [5,9]. Powstające rozwiązania i metody matematycznego podejścia do omawianego zagadnienia różnią się: przyjętymi geometrycznymi reprezentacjami przeszkód, rodzajem obiektu biorącego udział w ruchu, rodzajem przeszkody, sposobem uzyskiwania informacji o przeszkodzie itp.…”

“…This results from growing requirements for flight safety of piloted and unmanned flying objects. The proposed solutions and mathematical methods focused on the problem differ one from another due to geometrical representations of obstacles (Graffstein, 2012a;Park et al, 2012), types of moving objects, types of obstacles, methods of getting information about obstacles (Ariyur et al, 2005;Higuchi et al, 2012), etc.…”

In the paper, mathematical relationships which are used to describe kinematic variables of the aircraft-obstacles configuration and motion of the aircraft are presented. These define the base for the set of conditions enabling determination of the possibility and threat of collision. The second important aim of such a definition is creation of prerequisites for selection of an appropriate anti-collision manoeuvre, computation of reference signals and inequalities used as limitations on these signals in the automatic flight control process. Theoretical analysis is illustrated by an example of computer simulation of the flight of aircraft. Two anti--collision manoeuvres are studied in this experiment. The first one, performed in a vertical plane, consists in emergency climbing. The second one, performed in the horizontal plane, is shaped by three turns, each one of small radius, to go around the obstacle and then return to the previously realised flight path.

“…However, it is not used in small scale UAV due to its weight and size. Some of the research conducted in this field can be found in (Kumar & Ghose, 2001;Hyeon-Cheol & In-Kyu, 2004;Ariyur et al, 2005;Tatkeu et al, 2006;Kwag & Chung, 2007;Kemkemian et al, 2009). An efforts toward extracting radar parameters for continuous and interrupt driven data acquisition techniques were covered by Albaker and Rahim (Albaker & Rahim, 2009a;Albaker & Rahim, 2011b).…”
