%Synopsis:
%  sigOut = aimtexfa2dbt(sigFa, noRangeBins, noPulses, noCPI, pulsecode, lambda)
%
%Description:
%  Converts a radar signal for the aimtEx radar system from FA's data
%  format to DBT format.
%
%Output and Input:
%  sigOut (RxRadarSigT): Output radar signal in DBT format.
%  sigFa (CxMultiMatrixT): Input radar signal matrix. XX(space,pulse,range,cpi).
%  noRangeBins (IntScalarT):
%  noPulses (IntScalarT):
%  noCPI (IntScalarT):
%  pulsecode (CxVectorT):
%  lambda (RealScalarT):
%
%--------
%Notations:
%  Data type names are shown in parentheses and they start with a capital
%  letter and end with a capital T. Data type definitions can be found in [1]
%  or by "help dbtdata".
%  [D] = This parameter can be omitted and then a default value is used.
%  When the [D]-input parameter is not the last used in the call, it must be
%  given the value [], i.e. an empty matrix.
%  ... = There can be more parameters. They are explained under respective
%  metod or choice.
