Abstract

The transmitting system is the core part of active sonar, its amplitude-frequency response is an important element to judge the system, and an important indicator to measure its performance is the bandwidth flatness of the amplitude frequency response. When the amplitude-frequency response is seriously undulate which means poor consistency, it may result in the signal amplitude distortion which is not conducive to the signal matching process, and is a great disadvantage to the stability and reliability of the sonar. In order to solve the amplitude-frequency response fluctuation problem, this paper proposes an algorithm using broadband equalization to compensate the amplitude-frequency response, it can be achieved by designing an FIR filter which is based on the compensation response to equalize the transmit signal.The experimental data results show that the developed technology can improve about 3.9dB gain compared to the method without equalization.The algorithm can set compensation response flexibly with small computation and has already been applied into the underwater acoustic engineering.
