Abstract :
We consider the characteristic polynomials of two-dimensional (2-D) harmonics. The concept of the eigenpolynomial of a 2-D harmonic signal is presented. A representation formula of the eigenpolynomial is given and proved. An advantage of the eigenpolynomials is that they can uniquely determine the frequency pairs of a 2-D harmonic signal.
