The development of quantum radar technology presents a challenge to stealth targets, so it is necessary study the detection probability. In this study, an analytical expression cross section (QRCS) for complex targets presented. Based on QRCS expression, calculation method probability creatively proposed. Moreover, self-designed flying-wing aircraft adopted obtain distributions conventional and in different directions. As revealed by result probabilities are significantly different, has...
Active tracking control is essential for UAVs to perform autonomous operations in GPS-denied environments. In the active task, take high-dimensional raw images as input and execute motor actions actively follow dynamic target. Most research focuses on three-stage methods, which entail perception first, followed by high-level decision-making based extracted spatial information of target, then UAV movement control, using a low-level controller. Perception methods deep neural networks are...
For tilt-rotor aircraft with coaxial rotors (coaxial rotor aircraft), reduction of radar cross section as well acoustic noise can be essential for stealth design, and the rotation have an influence on dynamic (RCS) characteristics. In this paper, approach to prediction both sound pressure level (SPL) RCS coaxial-tilt is carried out, based theories FW-H equation, physics optics method (PO) physical theory diffraction (PTD) method. order deal rotating parts (mainly including rotors), a...
Purpose By reducing the coating thickness of weak scattering source, weight absorbing material can be reduced by 35% with little effect on RCS. Design/methodology/approach To alleviate weight-increasing problem caused a large number materials, method for zonal materials stealth helicopter was proposed. appropriately at secondary locations, amount used is significantly reduced. Findings Compared full-coated, scheme achieves corresponding RCS reduction effect. Practical implications Zonal...
This study proposed a novel handover bicasting scheme for long term evolution (L TE) system. The conventional makes the decision according to signal-to-noise ratios (SNR) minimize packet delay time and aim at seamless connectivity during processing period. However, SNR-based cannot optimize efficiency of backhaul resource utilization quality service (QoS) users. Instead using SNR as traditional mechanism does, exploits success rates (PSR) link estimator in order simultaneously reduce waste...
Abstract The disordered bonds of a‐Si:H may generate a redistribution trapped states with strain bending. redistributed deep saturate multiple mechanical bending cycles, and it would improve the reliability drain current stress TFTs on flexible substrates. It is possible to produce low cost highly uniform AMOLED systems for display applications using array backplanes.
Quantum radar is a novel detection method that combines and quantum technologies. It exceeds the threshold poses threat to conventional stealth targets. This work aims derive expression of cross-section new complex target. The calculation formula QRCS was derived after introducing relative photon parameters vector dot product. Subsequently, comprehensive optimization model lift–drag ratio based on genetic algorithm proposed for waverider warhead. During process, we an with objective function...
Due to the constant development of quantum radar technology, it has become increasingly important study scattering properties radars typical targets. In this study, analytical expression triangular pyramid is determined by solving Fourier transform each plane pyramid, and their cross-section, propose a solution equivalent transformation elevation angle azimuth inclined plane. Besides, based on simulation result QRCS, can be seen that results obtained using calculation are consistent with...
