MODEL FOR EVALUATING THE PARAMETERS OF CORNER REFLECTORS FOR AERIAL TARGETS

An important element of the target equipment of modern and prospective target drones is the means for simulating the radar cross-section (RCS) of various types of aerial targets in the microwave frequency band. The most common passive aerial target simulators are corner reflectors (triangular, square, circular, and biconical). Conducted research has shown that among corner reflectors for aerial targets, the square reflector provides the largest radar cross-section. However, it also has the narrowest backscattering patterns in both planes and a less robust structure. Triangular corner reflectors for aerial targets provide the widest monostatic backscattering patterns in both planes, which defines their advantages in use, despite their relatively low RCS value. Compared to others, corner reflectors are simple in design, manufacturable, possess high mechanical rigidity, and provide sufficiently good RCS values over wide ranges of illumination aspects with relatively small physical dimensions. A model for evaluating the parameters of corner reflectors for aerial targets has been developed. It allows for calculating their values based on input data about the target's radar cross-section and the frequency of the illuminating electromagnetic wave. The obtained simulation data confirm the prospects of using the developed model for evaluating corner reflector parameters when creating targets for air attack means
