Abstract

Spread spectrum pulse compression can be used as a method for reducing peak power so that it is within the bounds of safety guidelines set by the American Institute of Ultrasonic Measurements (AIUM). Pulse compression accomplishes this by implementing a longer length transmitted pulse of lower amplitude while maintaining the same signal gain, resolution, and signal-to-noise ratios. Here, correlation algorithms for implementing such a subsystem are described, as well as computer simulation results for methods that reduce correlation sidelobe levels resulting from that process
