Abstract
Program dwholeprinceresp.f90 computes responses at receivers of a detection/discrimination system in the time domain to an induced magnetic dipole polarizability object specified in the frequency domain, in a whole space of a given conductivity. Magnetic fields of a set of loop transmitters are propagated through the conductive medium (e.g. seawater) to an object whose magnetic dipole moment polarizabilities are specified in the frequency domain, the resultant induced magnetic moments calculated, the magnetic fields of the induced moments the propagated to a set of user specified receivers (approximated as point dipole receivers), the response at the receivers is convolved with the transmitter waveform, and the result inverse Fourier transformed to get the time domain response at the receivers. The time domain response of the receivers to the primary (direct) transmitter magnetic field is computed separately in a similar manner. Transmitter loops may be approximated with any number of line segments, and any number of receivers may be specified. Square pulse and half sine pulse transmitter wave forms of arbitrary duration are modeled. The waveform may be uni-modal or bi-model (alternating sign). The polariability object may be positioned and oriented arbitrarily with respect to the system.
