Member Function Documentation

bool clBeamDipole::AddData (   )

Add data to integration buffers. Call this after calling clArrayDipole::AddData() Returns >= 1 when integration buffers are full and ready to be processed by Process(), call until returns 0 before calling clArrayDipole::AddData() again. Returns: Status Definition at line 73 of file BeamDipole.cc. References Array, Data, DSPBank, GDT, clArrayDipole::GetFiltPtr(), lBaseIdx, lSampleCount, and lWinSize. Referenced by clDirection::ProcessData().

GDT clBeamDipole::Process (  GDT   )

Process data in integration buffers and return result. This can be called many times for different directions. Parameters: fDirection  Direction (rad) Returns: Normalized energy Definition at line 90 of file BeamDipole.cc. References Array, Data, GDT, clArrayDipole::GetDelaySamples(), lBaseIdx, and lSampleCount. Referenced by clDirection::CalcDipoleBeams().

void clBeamDipole::SetHistory (   )

Set history part of buffer. Call this between last call of Process() and next call of AddData(), this will copy data from end of integration buffer to start of integration buffer. Definition at line 125 of file BeamDipole.cc. References Data, DSPBank, GDT, lBaseIdx, and lSampleCount. Referenced by clDirection::CalcDipoleBeams().

GDT clBeamDipole::GetPeakLevel (   )

Get peak level (in dB) of integration buffer. Returns: Peak level (dB) Definition at line 139 of file BeamDipole.cc. References Data, DIR_DB_SCALE, DSPBank, GDT, lBaseIdx, and lSampleCount. Referenced by clDirection::ProcessData().

GDT clBeamDipole::GetIntegrationTime (   )  [inline]

Get real integration time. Returns: Integration time (s) Definition at line 98 of file BeamDipole.hh. References fIntTime, and GDT. Referenced by clDirection::InitArray().
