Book Description
This theses deals with improving the miss distance of a missile, with imaging seeker(s), by utilizing dynamic image processing. In an encounter with a missile, a target tries to avoid the missile by performing a evasive maneuver when the missile is at a relative distance which maximizes the miss distance. Dynamic image processing permits us to identify the evasive maneuver of the target by estimating its acceleration in magnitude and direction. This thesis studies methods of utilizing this additional information about the target's behavior in order to improve the missile's performance. First the proportional navigation guidance law is explored in order to verify its advantages and weaknesses. Then, methods of obtaining the time dependent 3-D movement of a target from its image plane feature point correspondences are derived. The 3-D components of the target's acceleration are obtained by using a Kalman filter. Missiles with two cameras, one camera and one seeker (radar or IR), and only one camera are considered. Methods to get stereo vision by using the one camera plus one seeker setup and the single camera setup are proposed. Advanced guidance laws, namely advanced proportional navigation and optimal guidance, are derived for a 3-D environment. A three dimensional simulation program is developed using classical proportional navigation, advanced proportional navigation, and optimal guidance. The engagement is simulated using state variable design and the performance of the guidance laws is compared ...

Book Description
First of all, we want to congratulate two new research communities from M- ico and Brazil that have recently joined the Iberoamerican community and the International Association for Pattern Recognition. We believe that the series of congresses that started as the “Taller Iberoamericano de Reconocimiento de Patrones (TIARP)”, and later became the “Iberoamerican Congress on Pattern Recognition (CIARP)”, has contributed to these groupconsolidatione?orts. We hope that in the near future all the Iberoamerican countries will have their own groups and associations to promote our areas of interest; and that these congresses will serve as the forum for scienti?c research exchange, sharing of - pertise and new knowledge, and establishing contacts that improve cooperation between research groups in pattern recognition and related areas. CIARP 2004 (9th Iberoamerican Congress on Pattern Recognition) was the ninthinaseriesofpioneeringcongressesonpatternrecognitionintheIberoam- ican community. As in the previous year, CIARP 2004 also included worldwide participation. It took place in Puebla, Mexico. The aim of the congress was to promote and disseminate ongoing research and mathematical methods for pattern recognition, image analysis, and applications in such diverse areas as computer vision, robotics, industry, health, entertainment, space exploration, telecommunications, data mining, document analysis,and natural languagep- cessing and recognition, to name a few.

Book Description
Progress on real-time spatial light modulators, image pattern recognition and optical signal processing for missile guidance is documented. A full description of our test and evaluation of the Soviet PRIZ spatial light modulator is inxcluded. In image pattern recognition, a unified formulation of four different and new types of synthetic discriminant functions is advanced. These include synthetic discriminant functions for intra and inter-class pattern recognition and multi-class pattern recognition. In the area of image pattern recognition, we also advance new statistical synthetic discriminant function filter concepts and a new principal component synthetic discriminant function. These analyses utilize new performance measures and new image models. Conventional holographic pattern recognition research conducted under AFOSR support is also reviewed. Our new AFOSR optical signal processing research concerns optical matrix-vecgtor processors. Initial research in this area includes fabrication of a fiber-optic microprocessor-based iterative optical processor and its use in adaptive phased array radar processing and for the calculation of eigenvalues and eigenvectors of a matrix.
