classdef RadarData < BeamHeader
	% RadarData  class representing one beam's header and IQ data along with given reference data.
	%
	%   Each instance holds the 1024-byte binary header fields parsed by
	%   read_raw_file, the raw complex IQ BeamData cube, and optional
	%   post-processing and reference fields

	properties
