WebThe present paper addresses the question of monostatic radar cross section (RCS) measurements. Circular disk monostatic RCS was experimentally investigated at different frequencies. Achieved experimental results were used for calibration of scaled model monostatic and bistatic RCS measurements. Measurement technique was realized by the …
WebMar 20, 2013 · Based on the study of the radiation and scattering of the circularly polarized (CP) antenna, a novel radar cross-section (RCS) reduction technique is proposed for CP antenna in this paper. Quasi-fractal slots are applied in the design of the antenna ground plane to reduce the RCS of the CP antenna. Both prototype antenna and array are … Webunit area in a plane wave incident on the scatterer from a specified direction. where σ is the RCS of the target, R the range between radar and target, E s the scattered electric field, and E o the incident electric field.
