Executive Summary
This thesis details the design and development of a four-element end-fire array as a seismo-acoustic sonar source for buried landmine detection. The array, consisting of vertical-motion inertial mass shakers, was tested on Del Monte Beach to preferentially excite Rayleigh waves. Results showed effective end-fire beam patterns with significant suppression to the rear, demonstrating its potential for enhancing landmine detection capabilities.
Why It Matters
This document is crucial for defense analysts as it details the development of a specialized seismo-acoustic sonar system designed to improve the detection of buried landmines, a persistent threat to naval forces and ground operations. Enhanced mine detection capabilities directly impact force projection, operational safety, and strategic mobility in littoral and contested environments.
Key Takeaways
- A four-element end-fire array was successfully developed and tested as a seismo-acoustic sonar source for buried landmine detection.
- The system preferentially excites Rayleigh waves, which are effective for target echo location in the surface region of the ground.
- Testing demonstrated effective end-fire beam patterns with 15 dB suppression to the rear, indicating directional capability for mine detection.],
Strategic Relevance
The development of seismo-acoustic sonar for landmine detection is strategically important for military operations, particularly for naval forces operating in littoral environments. It enhances force protection, enables freedom of maneuver, and reduces the logistical and human costs associated with traditional mine clearance methods. This technology can significantly accelerate post-conflict stabilization and humanitarian efforts.
