WebPlot the radar cross section (RCS) pattern of a truncated cone as a function of elevation for a fixed azimuth angle of 5 degrees. The cone has a bottom radius of 9.0 cm and a top radius of 12.5 cm. The truncated cone height is 1 m. The operating frequency is 4.5. Define the truncated cone geometry and signal parameters. Webof 1 m2 then the RCS of the target is given by: RCStgt (dBsm) = RCSstd (dB) - RCStgt (dB) The data is expressed in dBsm, or decibels referenced to one square meter. Radar …
WebApr 16, 2024 · It doesn't take much to produce a radar reflection. -40 dBsm corresponds to a sphere just 1.4 cm in diameter. Anything that contains metal or water will reflect radar. Even small metal or flesh objects will produce a significant return. WebRadar cross section (RCS) is a measure of the electromagnetic energy intercepted and reradiated at the same wavelength by any object. The dimensions are those of an area, usually square meters (m 2) or decibels relative to a square meter (dBsm). The relationship between square meters and dBsm.
