function sigSum = addsig(sig1, sig2)

%ADDSIG Adds two radar signals.
%
%--------
%Synopsis:
%  sigSum = addsig(sig1, sig2)
%
%Description:
%  Adds two radar signals. First, it copies the fields of "sig1" to the
%  output signal "sigSum" and then adds the "signals" field of "sig2" to
%  the "signals" field of "sigSum".
%
%Output and Input:
%  sigSum (RxRadarSigT): Output radar signal.
%  sig1 (RxRadarSigT): First input radar signal. The fields of this radar signal
%    will be retained in the output radar signal "sigSum".
%  sig2 (RxRadarSigT): Second input radar signal.
%--------
%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.
