Abstract

In shallow water, the performance of the operating active sonar systems is usually limited by reverberation. One of the measure to overcome the negative effect of reverberation is of selecting an adequate transmission pulse. SFM(Sinusoidal Frequency Modulation) pulse has been received a considerable attention as a candidate for suppressing the reverberation effect. In this paper, we analyze the detection performance of SFM pulse with respect to modulation frequency and bandwidth. To conduct the analysis. we synthesize the signal at the receiver considering. the transmitter. the receiver, and the propagation medium characteristcs. The simulations provide the optimum modulation frequency and bandwidth under the given situation.
