A three-dimensional visualization method of complex coherent signals

The invention discloses a complex coherent signal three-dimensional visualization method comprising a step 1) of reading a complex coherent signal pairs s1 and s2 to be visualized, and constructing acomplex coherent matrix C by second-order statistical averaging; a step 2) of based on the complex coherent matrix C constructed in the step 1), calculating a parameter c0 reflecting the power sum ofs1 and s2, a parameter [beta] describing the relative power difference of s1 and s2, and a complex coherence coefficient [gamma] between s1 and s2; a step 3) of based on the parameters c0, [beta] and[gamma] obtained in the step 2), further calculating parameters c1, c2 and c3 so as to constitute a coherent vector c together with the parameter c0; a step 4) of constructing a three-dimensional coherent sphere based on the coherent vector c obtained in the step 3) so as to visualize all degree of freedom information of the complex coherent signal. The complex coherent signal three-dimensional visualization method completely describes the power information and the coherent information of the complex coherent signal by expanding a traditional two-dimensional circular map into a three-dimensional coherent sphere.
