Time-series modeling using the waveform transmission through a channel program

DRDC Atlantic has developed a coherent transmission loss model that simulates the propagation of acoustic pulses through an ocean environment. Using a set of input eigenrays and an input waveform, the WATTCH (waveform transmission through a channel) model can generate a set of output time series. Each time series represents the expected signal corresponding to a given range and depth. Assuming the required eigenrays can be generated, WATTCH can simulate the effects of complex environments. This is illustrated by examples comparing measured data to modeled data in two environments. In adddition, an example is provided using WATTCH to model data for testing a target detection algorithm.
