color-coded polar data plot

I would like to display an array of data with polar dependence in polar (r,phi) coordinates. The values of the data shall be color-coded. A single data point shall be represented by an area filled with the respective color. The center of the area is r_i, phi_1, the limits of the area is given by r_i +/-delta_r , phi_i +/- delta_phi. This data plot is typical for radars (PPI = plan position indicator). Any idea whether this is possible with Mathcad? A example is enclosed.
