Conical-Scan Antennas for W-Band Radar Systems
Conical-scam implementations for three antenna types are discussed in terms of the beam nuiatioa method, reference signal generation and angle error demodulation Various applications for these antennas including their use in teaching are discussed. Inder Terms-..eoaical-sean, millimetre wave, antenna I. IN'RODUCiTON Tracking radars require a mechanism to determine the offset of a target from th...
متن کاملA Remote Pointing Technique Using Pull-out
Reaching objects displayed on the opposite side of a large multi-touch tabletop with hands is difficult. This forces users to move around the tabletop. We present a remote pointing technique we call HandyPointing. This technique uses pull-out, a bimanual multi-touch gesture. The gesture allows users to both translate the cursor position and change control-display (C-D) ratio dynamically. We con...
متن کاملConical scan polarization-sensitive optical coherence tomography.
We report on a new articular cartilage imaging technique with potential for clinical arthroscopic use, by supplementing the variable-incidence-angle polarization-sensitive optical coherence tomography method previously developed by us with a conical beam scan protocol. The technique is validated on bovine tendon by comparing experimental data with simulated data generated using the extended Jon...
متن کاملSpacecraft Attitude Control with Precise Pointing the Flexible Antennas?
New approach for modelling a physical hysteresis damping the flexible spacecraft structure oscillations, is developed. New results on communication satellite attitude guidance and digital robust control with precise pointing the large-scale flexible antennas, are presented.
متن کاملSecuring Scan Design Using Lock & Key Technique
Scan test has been a common and useful method for testing VLSI designs due to the high controllability and observability it provides. These same properties have recently been shown to also be a security threat to the intellectual property on a chip [1]. In order to defend from scan based attacks, we present the Lock & Key technique. Our proposed technique provides security while not negatively ...
