Abstract

The design, programming and application of a novel and cost effective digital signal processing (DSP) platform is described, whose speed, large dynamic range and stability renders it suitable for NDE applications that mandate the extraction and identification of very weak signals embedded in noise. The system has been deployed both for the isolation of weak magnetic fields propagated through a ferrous steel boundary, and in the recovery of ultrasonic signals transmitted through seawater and severely attenuated by divergence losses.
