Vahid Cheraghi Mahmudabadi; Hadi Makarem; Majid Hatam

Volume 4, Issue 3 , November 2020, Pages 24-15

Abstract
  Navigation errors in synthetic aperture radar (SAR) applications lead to phase errors in SAR echo signal and image quality degradation. Among different phase errors, zero and first order errors have no effect on image quality, while second and higher order terms are very important. The majority of second ...  Read More

abdollah asadollahi; Sanaz Nikaein; Davood Ramesh

Volume 4, Issue 3 , November 2020, Pages 35-43

Abstract
  This article presents a novel and comprehensive approach to conceptual design of expander cycle liquid engines. One advantage of the computational code developed is the possibility of considering the working regime without cavitation of pumps by maximizing specific impulse of the engine system. Based ...  Read More

Target Detection System Design for Domestic Areas in Iran: Case Study in Abadan and Ahvaz, Using Satellite Multi-spectral Images of Landsat 8 and Sentinel 2

Maryam Imani

Volume 4, Issue 3 , November 2020, Pages 45-63

Abstract
  Hyperspectral images provide worthful spectral information for target detection. Since these images are not available in Iran, we use multi-spectral images with approximately 10 bands. Due to differences of hyperspectral and multi-spectral images, a target detection system (using multi-spectral images) ...  Read More

An Overview of Modeling, Stability, and Control of Flapping Robots

Sorayya Leyci; javad poshtan

Volume 4, Issue 3 , November 2020, Pages 65-76

Abstract
  Flapping drones have been the focus of attention for various reasons, such as the ability to fly scilently at low speeds and also high maneuverability. This article describes the history of flapping robots and their importance in engineering and how to obtain the forces required to fly. Then, by examining ...  Read More
