The use of sinusoidal frequency modulated pulses for low-Doppler detection

摘要

This paper describes in-water testing of the reverberation gain achievable with broadband, Doppler sensitive sinusoidal frequency modulated (SFM) transmissions. Theoretical predictions via the Q-function are compared to experimental results in shallow water using static and moving sonar platforms. The coherence of target echoes is examined through the use of an echo-repeater.
