Abstract:

In this report we describe experiments carried out at the DRDC Atlantic tank facility with the high frequency broadband Multi-Mode Pipe Projector MMPP. In particular, we examine the fidelity with which one can produce specified broadband pulses with and without compensation for the transducers spectral characteristics. It is shown that extended pulses or pulse sequences can be accurately produced and that matched filtering very effectively compresses the time series in the case of extended pulses. In addition, the vertical beam pattern of the transducers is discussed and the results of some experiments with 2 transducers are also presented.
