Independent Random Recurrent Neural Networks for Infrared Spatial Point Targets Classification
Exo-atmospheric infrared (IR) point target discrimination is an important research topic of space surveillance systems. It is difficult to describe the characteristic information of the shape and micro-motion states of the targets and to discriminate ...

R2FA-Det: Delving into High-Quality Rotatable Boxes for Ship Detection in SAR Images
Recently, convolutional neural network (CNN)-based methods have been extensively explored for ship detection in synthetic aperture radar (SAR) images due to their powerful feature representation abilities.

Analysis and Design of M-Channel Hybrid Filter Bank With Digital Calibration
Hybrid filter bank (HFB) is widely used in frequency-interleaved analog-to-digital converters, but traditional HFB structures suffer various degrees of imperfections. This paper presents a new-structure HFB based on power complementary pair. The proposed

Radar Target Localization with Multipath Exploitation in Dense Clutter Environments
The performance of classic radar geometry based on the line-of-sight (LOS) signal transmitted from radar to the target in the free space is affected by multipath echoes in urban areas, where non-line-of-sight (NLOS) signals reflected by obstacles are ...

Time course of target recognition in visual search [PDF]
Visual search is a ubiquitous task of great importance: it allows us to quickly find the objects that we are looking for. During active search for an object (target), eye movements are made to different parts of the scene.

A bottom–up model of spatial attention predicts human error patterns in rapid scene recognition [PDF]
Humans demonstrate a peculiar ability to detect complex targets in rapidly presented natural scenes. Recent studies suggest that (nearly) no focal attention is required for overall performance in such tasks.

Range migration compensation for moving targets in chirp radars with stepped frequency
Long-time coherent pulse integration method has been extensively used in detecting weak targets, but the detection performance is affected by range migration (RM) due to high radial velocity.
