Unpowered laser- guided Missile (ULGM) has not only gained a predictably receptive attention but also has successfully adapted to fast changing warfare market. The inaccuracy, which often result in the need to fire many rockets to hit a single target, has led to the search for a means to guide the rocket towards its target. This significant feature in conjunction with the high degree of complexity associated with the generation of state variable representation from the nonlinear control model of ULGM have made linearization and matrix representation of the model very attractive. Of course, it facilitates the understanding of system dynamics of unpowered laser-guided missile.

Introduction The Both the radar beam and its reflected illumination have had an extraordinary standing in their use for missile guidance. In such a system, the target is illuminated with a radar beam and the missile is made to track the path of the reflected illumination from the target [1]. The issues of weight, complexity, adaptability, and operational difficulty are known to be associated with beam illuminators [2]. The prominence of ULGM began to emerge in the early 1960s because of the significant feature of a guidance system that steers them towards a pre-selected target and its embedded accuracy and reliability which often reduced the need to fire many rockets to hit a single target. This has significantly contributed to the growth and sophistication of military capability all over the world and consequently, the course of recent wars. The healthy consideration of merging existing rocket technology with enabling technology which provides the potential for very intensive utilization of radar and radio detection devices is uniquely responsible for dawning of the era of high-technology warfare, an era that quickly demonstrate its problems as well as its promise. The launch of projectiles, rockets and missiles has been a laboratory curiosity ever since. What has changed is the generous helping of control theory to provide an exact and balanced knowledge-based understanding of their nonlinear nature, aerodynamic instability caused by the location of centre of gravity behind the centre of drag, and consequently, successful flight.
