Abstract: The scope of Guidance and Tracking and Classification encompasses many disciplines, including infrared, far infrared, millimeter wave, microwave, radar, and synthetic aperture radar sensors as well as the very dynamic topics of signal processing, computer vision, and pattern recognition. It is a fertile area for growth in both analysis and experimentation in military applications. The availability of ever improving computer resources and continuing improvement in sensor performance has given great impetus to this field of research. This technology "push" has been balanced by a technology "pull" resulting from increasing demand from potential users of this technology including both military and civilian entities as well as needs arising from the growing field of Homeland Security. The original tentative of guidance control has been focused mostly on the development of target detection, tracking, and classification associated with visible range sensors in day and in other hostile environments. In the last decade, infrared, thermal and other non-visible imaging sensors were used in special areas like military. That lower interest level in heat sensors was due in part to the high cost of non-visible range sensors, low image resolution, high image noise, lack of widely available data sets, and lack of consideration of the potential advantages of non-visible lights. These historical objections are becoming less relevant as infrared imaging technology advances and their cost is dropping dramatically. Image sensing devices with high dynamic range and high IR sensitivity have started to appear in a growing number of applications ranging from military and automotive domains to home and office security applications. In order to develop robust guidance and tracking system and accurate systems that operate in and beyond the radar frequency range, not only existing methods and algorithms originally developed for the existing range should be improved and adapted, but also entirely new systems that consider the potential advantages of frequency ranges are certainly required. The fusion of visible and non-visible ranges, like radar and IR images, or thermal and visible spectrum images, is another dimension to explore for a higher performance of vision-and-signal based systems. The tracking system is widely employed in visionbased systems, and many detection and recognition systems available today are relying on physiological phenomena produced by IR and thermal wavelengths.. It has to be noted that this paper is the result of the seminar report of the UG BE curriculum of the 8th semester that was undertaken by Mr. Naveen under the guidance of the faculty & the HOD.
