Military Security System and Rocket Launching System

Abstract

This paper presents an integrated radar-based military security system with a projectile-based rocket launching mechanism. For real-time object detection and ranging, the system uses an Arduino-controlled radar unit with an ultrasonic sensor fixed on a servo motor. The radar finds targets within its operational range by scanning a predetermined area. Automatic acquisition and processing of detected objects enables the rocket launcher to modify its trajectory for increased accuracy. Real-time data collection, processing, and control are made possible by the Arduino platform, which allows for smooth communication between the radar and launcher. The launching system\'s effectiveness is greatly increased in a variety of operational scenarios thanks to this automated integration, which enables dynamic target locking and trajectory correction.

Introduction

The research presents an innovative ultrasonic radar system using an Arduino microcontroller, an ultrasonic sensor mounted on a servo motor, and a rocket launcher to enable real-time obstacle detection, target tracking, and automated projectile firing. Unlike traditional electromagnetic radar, this system uses ultrasonic waves for short-range detection, offering a cost-effective and reliable alternative. The radar continuously scans its environment, maps detected objects on a graphical interface, and dynamically adjusts the rocket launcher’s aim for precise targeting.

Experimental tests showed high accuracy (within 40 cm range and <5% error) and robust performance in various conditions, including indoors and outdoors with noise interference. The system demonstrated fast and accurate target engagement, enhancing decision-making speed while reducing human errors in defense scenarios.

Applications span military and defense (automated targeting, border security), surveillance (intrusion detection, perimeter protection), and navigation (autonomous vehicle obstacle avoidance, assistance for visually impaired). Future improvements include extending detection range, 3D visualization, AI-driven adaptive tracking, and enhanced sensor fusion.

Conclusion

The evolution of the ultrasonic radar-integrated projectile system showed a real-world solution for short-range detection and automated targeting. The system proved to successfully achieve reliable performance in obstacle detection and dynamic target engagement, with indications of its applicability in defence and security fields. Although there are some limitations on range and visualization, the system is still affordable, energy efficient, and scalable. Upgrades in the future—e.g., integration with machine learning, increased detection range, and better visualization—may have a big impact on performance. Overall, the project presents a cost-effective and scalable method for radar-based automated systems.
