Abstract

The Guidance commands are mostly generated by determining of the line of sight (LOS) angle. Among the existed Guidance laws, proportional navigation (PN) is the most widely used algorithm. In this way, the differentiation of the LOS angle is required. Then the LOS rate are usually computed by numerical differentiation of the LOS angle. The LOS rate can be directly measured by an embedded internal seeker which it would be a differential free technique. Nowadays, in practical, guidance algorithms equipped with a seeker have been interested. Such a guidance loop includes some subsystems like vehicle dynamics, the type of flight path and also navigation sensors. Each subsystems may have some parameters as well as aerodynamic coeficients. Thererfore the Guidance System Performance would be affected by changing in these parameters. In this paper, in a typical vehicle equipped with a seeker, the guidance system efficiency would be numerically investigated in terms of the aerodynamic coeficients change.
