Optical-radar imaging of scale models for studies in asteroid astronomy [PDF]
, 1995 During the past five years, delay-Doppler radar has become the primary technique for studying the structure of Earth-crossing asteroids. None of these objects has yet been visited by spacecraft, so ground-truth test cases are lacking. A laboratory system

3D Printing of Stretchable, Compressible and Conductive Porous Polyurethane for Soft Robotics
Advanced Materials Technologies, EarlyView.A 3D‐printable porous dopamine‐polyurethane acrylate elastomer results in conductive, stretchable, and compressible structures that can be metallized in situ through catechol‐mediated silver reduction. The resulting material function as both compliant soft robot with a and strain sensors without complex assemblies, enabling fully 3D‐printed soft ...

Сonceptual design of small spacecraft with a high resolution P-VHF band bistatic SAR system
Вестник Самарского университета: Аэрокосмическая техника, технологии и машиностроение, 2017 Spatial resolution is one of the most important characteristics of a radar image. Significant limitations in communication regulations should be taken into account concerning radar facilities in long-wave frequency ranges (P or VHF). These limitations do
