Study to investigate and evaluate means of optimizing the Ku-band combined radar/communication functions for the space shuttle [PDF]

The performance of the space shuttle orbiter's Ku-Band integrated radar and communications equipment is analyzed for the radar mode of operation. The block diagram of the rendezvous radar subsystem is described. Power budgets for passive target detection

A New Method of Robust Ground Moving Target Detection Under Different Backgrounds of Airborne SAR Based on Spatial Deformable Module

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing
Combined with the synthetic aperture radar (SAR) imaging algorithm, diverse simulation sample sets of ground moving targets are constructed to tackle the problem of insufficient measured data in the SAR ground moving target indication algorithm based on ...

A Clutter Suppression Approach for SAR-GMTI Based on Dual-channel DPCA

Leida xuebao, 2014
The Displaced Phase Center Antenna (DPCA) technology, a particular form of Space Time Adaptive Processing (STAP), has been widely used in Synthetic Aperture Radar Ground Moving Target Indication (SAR-GMTI).

Ehrhart clutters: Regularity and Max-Flow Min-Cut [PDF]

, 2010
If C is a clutter with n vertices and q edges whose clutter matrix has column vectors V={v1,...,vq}, we call C an Ehrhart clutter if {(v1,1),...,(vq,1)} is a Hilbert basis.

T-LESS: An RGB-D Dataset for 6D Pose Estimation of Texture-less Objects

, 2017
We introduce T-LESS, a new public dataset for estimating the 6D pose, i.e. translation and rotation, of texture-less rigid objects. The dataset features thirty industry-relevant objects with no significant texture and no discriminative color or ...

Foveation-based Mechanisms Alleviate Adversarial Examples [PDF]

, 2016
We show that adversarial examples, i.e., the visually imperceptible perturbations that result in Convolutional Neural Networks (CNNs) fail, can be alleviated with a mechanism based on foveations---applying the CNN in different image regions. To see this,

Clutter Suppression Technology Based Space-time Adaptive ANM-ADMM-Net for Bistatic SAR

Leida xuebao
Bistatic Synthetic Aperture Radar (BiSAR) needs to suppress ground background clutter when detecting and imaging ground moving targets. However, due to the spatial configuration of BiSAR, the clutter poses a serious space-time nonstationary problem ...
