Abstract: The development of an active sonar system requires information on the desired properties of the waveforms transmitted by the system. This article is based on MATLAB simulations and explores the Doppler sensitivity characteristics of various existing and proposed waveforms for underwater active sonar applications. As many as seven different waveforms were compared for Doppler sensitivities based on their matched filter responses.
