We study the two-dimensional(2-D) Regular Nonuniform Short-Time Fourier Transform(RNSTFT). A 2-D window function used in the 2-D RNSTFT is given by using two 1-D window functions, which can have arbitrary time and frequency resolutions under constraint of the uncertainty principle with arbitrary regularity order. We use the frame operator design method for designing synthesis windows in 1-D RNSTFT. It can include over-sampling ratio in the design. Under several parameters, we give a design example of the 2-D RNSTFT.
