W radiolokacji do opisu własności odbijających obiektów stosuje się pojęcie skutecznej powierzchni odbicia σ. Mimo że skuteczna powierzchnia odbicia σ rzeczywistych obiektów radarowych ma złożony przebieg w funkcji kąta obserwacji θ, w literaturze nierzadko przedstawia się ją za pomocą pojedynczej liczby rozumianej najczęściej jako wartość średnia lub mediana σ(θ). Takie podejście należy traktować jako uproszczone. Umożliwia ono jednak przeprowadzenie pewnych porównań i klasyfikacji obiektów. W drugim z serii artukułów, dotyczących skutecznej powierzchni odbicia, scharakteryzowano stosowane w praktyce metody określania skutecznej powierzchni odbicia σ, w tym: metody określania σ obiektu w locie, metody pomiaru σ na poligonach zewnętrznych oraz metody pomiaru σ na poliginach wewnętrznych, w tym na poligonach typu compact range.

In this paper practical methods of determination of radar cross section are described. In flight determination, farfield range and compact range determination methods are presented. Modern determination methods enable designers to calculate RCS at the design phase, which is important especially for stealth objects. An RCS image of the object created this way becomes very useful when different objects have to be compared at production stage and the influence of different modifications on RCS has to be evaluated. Prior knowledge of RCS (obtained through simulation) makes it possible to compare high resolution radar image with the calculated RCS image. This in turn enables modern radars to classify observed targets and, to some extent, recognize certain flying objects.
