Volume 17, Issue 1 , June 2024

https://doi.org/10.22034/jast.2024.428886.1170

Abstract
  A complete miss distance analysis of true proportional navigation is carried out due to initial heading error, step target maneuver, and seeker noise sources assuming a first-order control system using forward and adjoint methods. For this purpose, linearized equations are utilized for deterministic ...  Read More

Volume 16, Issue 2 , October 2023, , Pages 38-49

https://doi.org/10.22034/jast.2023.383679.1143

Abstract
  In this paper a new mid-course guidance algorithm for intercepting high altitude target is proposed. A part of target flight path is outside the atmosphere. The maximum acceleration command is designed as a variable constraint that varies with altitude. This physical limitation is happened for the aerodynamically ...  Read More

A Comprehensive Approach to Develop a Continuous Fuzzy Guidance Law for Maneuvering Targets

Labid Hassan; M.B. Malaek

Volume 9, Issue 1 , March 2012

Abstract
  Based on the idea of Continuous Fuzzy Guidance Law (CFGL), a andldquo;three-phase fuzzy guidanceandrdquo; (TFG) law is proposed for the class of surface to air homing missiles. The current approach enables the guidance law to track a maneuvering target from the beginning of the launch phase up to the ...  Read More
