MIMO radar space–time adaptive processing using prolate spheroidal wave functions [PDF]
, 2008 In the traditional transmitting beamforming radar system, the transmitting antennas send coherent waveforms which form a highly focused beam. In the multiple-input multiple-output (MIMO) radar system, the transmitter sends noncoherent (possibly ...

From Paths to Routes: A Method for Path Classification
Frontiers in Behavioral Neuroscience, 2021 Many animals establish, learn and optimize routes between locations to commute efficiently. One step in understanding route following is defining measures of similarities between the paths taken by the animals.

Hybrid Sidelobe Recognition Method Using Boresight Error and Quadrant Signal Difference for Monopulse Array [PDF]
Journal of Electromagnetic Engineering and Science, 2023 In this paper, a sidelobe recognition method using boresight error and quadrant signal difference for a monopulse array is proposed. A conventional sidelobe recognition method compares the difference between the sum and delta channels.

Comparison of Real Experimental and Simulated RCS of Flying Artillery Projectile [PDF]
Journal of Electromagnetic Engineering and Science, 2023 This study compares the actual experimental and simulation data of artillery projectiles (M107 projectiles) fired by a 155-mm gun. The experimental data are collected using a weapon-locating radar developed by LigNex1.

RGB-D object detection and semantic segmentation for autonomous manipulation in clutter [PDF]
Int. J. Robotics Res., 2018 Autonomous robotic manipulation in clutter is challenging. A large variety of objects must be perceived in complex scenes, where they are partially occluded and embedded among many distractors, often in restricted spaces.

A comparative study of linear and region based diagrams
Journal of Spatial Information Science, 2015 There are two categories of objects spatial information science investigates: actual objects and their spatial properties, such as in geography, and abstract objects which are employed metaphorically, as for visual languages.

Improved entropy-based autofocus correction for synthetic aperture radar
The Journal of Engineering, 2019 Autofocus is an essential step in order to obtain the well-focused synthetic aperture radar image. Compared to the non-parametric autofocus, the parametric way is not subjected to the prominent targets so much.
