Design of a Multiband and Wide Angle Reflector

Mojtaba Behzad Fallahpour; Hamid Dehghani; Ali Jabbar Rashidi; Abbas Sheikhi

Volume 12, Issue 4 , December 2019, Pages 47-56

Abstract
  Reflectors are a very important tools in counteracting the space borne or airborne SAR imaging systems. Because they can be used in the form of decoy and camouflage protection designs due to their high level RCS. The remarkable thing on this mission is that the SAR radar is capable of sending the wave ...  Read More

Investigation of the conduction effect on temperature-based attitude estimation

Marjan Moghanipoor; Maryam Kiani; S. Hossein Pourtakdost; Amir Labibian

Volume 12, Issue 4 , December 2019, Pages 91-102

Abstract
  Temperature sensors have recently been proposed for attitude estimation (AE) of Low-Earth satellites. However, since half of the satellite surfaces do not receive any heat flux from the Sun, conduction occurs among the satellite surfaces. In this regard, the present study has focused on the effect of ...  Read More
