Measurement and Analysis of Radar Signals Modulated by Flapping Wings of Birds

چکیده
There are arguments about the scattering mechanism of 10-dB periodic signal fluctuations posed by repetitive flapping motion in radar ornithology. We design a dynamic measurement system composed network analyzer and high-speed camera to track modulation on signals gaits birds within S-band, X-band, Ku-band. The results indicate that respiration contributes little bird’s signals, but wings contribute at least 10 dB fluctuation related echoes from flying birds, regarding different bands, observing angles bird species. Furthermore, contributions observed tests our theory time-varying wingbeat corner reflector (WCR) effect is correct explaining

NUMERICAL ANALYSIS OF MAVs FLAPPING WINGS IN UNSTEADY CONDITIONS
Today, Flapping Micro Aerial Vehicles (MAV) are used in many different applications. Reynolds Number for this kind of aerial vehicle is about 104 ~ 105 which shows dominancy of inertial effects in comparison of viscous effects in flow field except adjacent of the solid boundaries. Due to periodic flapping stroke, fluid flow is unsteady. In addition, these creatures have some complexities in kin...

15 صفحه اولCollective Flow Enhancement by Tandem Flapping Wings.
We examine the fluid-mechanical interactions that occur between arrays of flapping wings when operating in close proximity at a moderate Reynolds number (Re≈100-1000). Pairs of flapping wings are oscillated sinusoidally at frequency f, amplitude θ_{M}, phase offset ϕ, and wing separation distance D^{*}, and outflow speed v^{*} is measured. At a fixed separation distance, v^{*} is sensitive to b...
