Dbsm radar cross section
WebFeb 16, 2024 · dBsm, dB(m 2) – in radar, decibel relative to one square meter: measure of the radar cross section (RCS) of a target. The power reflected by the target is … レーダー反射断面積(レーダーはんしゃだんめんせき、英語: Radar cross-section, RCS)は、レーダーから電波の照射を受けたときにアンテナの方向に電波を反射させる能力の尺度。幾何学的な断面積、反射率、指向性の関数であり 、その反射波と等しい強度の電波を反射させることができる等方向性反射体の面積(完全導体で作られた球の断面積)で表される 。

WebDisplay the radar cross section (RCS) pattern as a function of azimuth and elevation for an elliptical cylinder whose semi-major axis is 12.5 cm and whose semi-minor axis is 9 cm. The cylinder height is 1 m. The operating frequency is 4.5 GHz. Specify the cylinder geometry and signal parameters.
WebThe units of radar cross section are square meters; however, the radar cross section is NOT the same as the area of the target. Because of the wide range of amplitudes typically encountered on a target, RCS is frequently expressed in dBsm, or decibels relative to one square meter. The RCS is the projected area of a metal sphere that is large ... manor house hotel stoke on trent reviewWebApr 10, 2024 · A new idea is proposed for a radar cross section (RCS) reduction metasurface, which consists of three types of artificial magnetic conductor (AMC) units. Using resonance circuit and transmission line theory, the reactance expression of an ideal AMC unit with a destructive phase difference is derived.
