“…In recent years, there are also discussions on such as Pérot cavity antenna [15,16], reflector antenna [17][18][19], lens antenna [18,[20][21][22][23][24][25][26][27][28], and horn antenna [29][30][31][32][33][34][35][36][37][38][39][40]. In [15], the phase shift feeder and the phase shift surface are designed using the LTCC technique and the holder is designed using the 3D printing technique.…”

This paper proposes a design of a multilayer controlled beam horn antenna for the D-band. The multilayer design can achieve easy to control, low cost, and compact structure. The designed structure achieves the effect of a conventional horn antenna by stacking multiple layers and realizes the effect of beam switching by modifying the multi-layer plate structure. The widest bandwidth can be obtained when stacking 4 layers of boards, covering 24.7% (110-141GHz) of the bandwidth with a simulation gain of approximately 13.5dBi. By replacing the third plate structure, beam switching of ±30 degrees can be achieved, and the gain after beam switching can also reach 11.5 dBi. Horn, antenna, D-band, beam switching, multi-layer.

“…In the RCS calculation for an electrically large and structurally complex vehicle, the shooting and bouncing rays (SBR) method is often used to track the multiple reflection paths of the radar rays and solve the surface reflection [4], and the uniform theory of diffraction (UTD) is used to calculate the edge diffraction [5]. By mixing the different high-frequency prediction methods, calculation accuracy and efficiency can be effectively ensured [6][7][8]. Unlike fixed-wing aircraft, rotorcraft have rotating parts such as rotors and tail rotors that are always in a high-speed rotating state.…”

To study the electromagnetic scattering of tilt-rotor aircraft during multi-mode continuous flight, a dynamic simulation approach is presented. A time-varying mesh method is established to characterize the dynamic rotation and tilting of tilt-rotor aircraft. Shooting and bouncing rays and the uniform theory of diffraction are used to calculate the multi-mode radar cross-section (RCS). And the scattering mechanisms of tilt-rotor aircraft are investigated by extracting the micro-Doppler and inverse synthetic aperture radar images. The results show that the dynamic RCS of tilt-rotor aircraft in helicopter and airplane mode exhibits obvious periodicity, and the transition mode leads to a strong specular reflection on the rotor’s upper surface, which increases the RCS with a maximum increase of about 36 dB. The maximum micro-Doppler shift has functional relationships with flight time, tilt speed, and wave incident direction. By analyzing the change patterns of maximum shift, the real-time flight state and mode can be identified. There are some significant scattering sources on the body of tilt-rotor aircraft that are distributed in a planar or point-like manner, and the importance of different scattering sources varies in different flight modes. The pre-studies on the key scattering areas can provide effective help for the stealth design of the target.
