Web29 de dez. de 2024 · The process of the measurement of the radar cross section of objects using a test range is described in this recommended practice. The term radar cross section (RCS) is defined, and the characteristics of different types of test ranges are given. The responsibilities of the test range operators are shown to involve test and calibration of the …
Web16 de abr. de 2024 · Extrapolating light aircraft RCS down to a glider, my best guess for the lowest-RCS gliders would be on the order of -10 to -5 dBsm, and no less than -12 dBsm or 0.05 m² due to the pilot. The reason is that a glider still contains a lot of non-radar-transparent parts, which will reflect radar frequencies and produce a sizable RCS. WebIN RADAR CROSS SECTION MEASUREMENTS* Lorant A. Muth National Institute of Standards and Technology Boulder, CO 80303 Abstract - Standards for radar cross section measure- ments are being developed cooperatively by NIST and DoD scientists.
