Angle Dependant Interference Patterns for Blast Vibration Minimization

The project focuses on reducing blasting vibrations at sensitive targets with phased source arrays in the far field. An interference pattern is naturally created by the geometrical setup of blasting arrays and the delay time between each single blast within the array. The aim is to create focusing effects with angle dependant interference where constructive energy hits sites of lesser interest and destructive interference is directed to neighbouring infrastructure. This work applies an analytic solution, which utilizes Dirac-Delta impulses, to better understand the basic relations between certain blast configurations and the resulting frequency radiation patterns. This is important because it signifies an additional constraint to the global search for optimized patterns in a later stage of the project.
