Study of the frequency distribution of secondary radiation resonances of small-sized pilotless vehicles.

Computer simulation of a typical small-sized pilotless vehicle is carried out. Three-dimensional diagrams of the secondary radiation (scattering diagrams) of the vehicles are derived. Frequency dependences of the secondary radiation in the range 50 MHz-4 GHz are plotted. The possibilities of the object model simplification are discussed. The polarization features of object detection are studied. The possibility of object recognition against the bird's background is evaluated. [ABSTRACT FROM AUTHOR]
