Characterizing Point Spread Function (PSF) fluctuations to improve Resident Space Object detection (RSO)

SPIE Proceedings, 2015
This research paper deals with methods for improving the performance of Electro-optical detection systems designed to find Resident Space Objects (RSOs). Some methods for detecting RSOs rely on accurate knowledge of the system Point Spread Function (PSF).

A Cognitive Radar for Classification of Resident Space Objects (RSO) operating on Polarimetric Retina Vision Sensors and Deep Learning

2019 IEEE International Conference on Imaging Systems and Techniques (IST), 2019
A novel cognitive radar, operating on Polarimetric Dynamic Vision Sensor (pDVS) and deep learning principles, aimed at discriminating moving targets, based on their motion patterns, is presented. The system consists of an asynchronous event-based neuromorphic imaging sensor coupled with polarization filters which enable better discrimination; a ...
