Distributed radar network for real-time tracking of bullet trajectory

Gunshot detection, sniper localization, and bullet trajectory prediction are of significant importance in military and homeland security applications. While the majority of existing work is based on acoustic and electro-optical sensors, this paper develops a framework of networked radar systems that uses distributed radar sensor networks to achieve the aforementioned objectives. The use of radio frequency radar systems allows the achievement of subtime- of-flight tracking response, enabling to response before the bullet reaches its target and, as such, effectively leading to the reduction of injuries and casualties in military and homeland security operations. The focus of this paper is to examine the MIMO radar concept with concurrent transmission of low-correlation waveforms from multiple radar sets to ensure wide surveillance coverage and maintain a high waveform repetition frequency for long coherent time interval required to achieve return signal concentration.

Partitioning algorithm for path determination of automated robotic part delivery system in manufacturing environments

This paper presents a student research project as a supplement to the undergraduate curriculum for students in the area of Science, Technology, Engineering and Mathematics. The goal of the project presented in this paper is to provide students with experience in design of a routing path for an automated robotic part delivery system in manufacturing environments. Despite all advancement in automation of manufacturing processes, still there are many challenges that need attentions in automating part transformation between manufacturing stations on an unstructured plant. In this study, first a mathematical model of a plant layout containing static obstacles is constructed. A partitioning algorithm is then introduced that partitions the layout into obstacle-free regions. Next, a searching algorithm is utilized to yield all possible combinations of regions that can connect a starting point to a destination throughout the plant layout. Finally, physical paths are constructed by drawing line segments within the obstacle-free regions and through the intersections between the regions. A program in C language has been developed that accommodates the algorithm introduced. Excellent level of success has been measured in the performance of the designed algorithm and program code. This study could be potentially beneficial to the industry since it tends to remove the labor costs.
