Abstract
The method of the present invention comprises displaying an image comprising reflected pulsed doppler signals in real time produced by reflecting a reference pulsed doppler signal, each reflected signal displayed in a color defined by a polar coordinate plot, wherein the polar coordinate plot comprises an origin representing reflected signals of the reference pulsed doppler signal having zero amplitude and zero frequency. The polar coordinate plot further comprises an axis representing reflected signals of the reference pulsed doppler signal having zero frequency, a radius with respect to the origin representing amplitude information of reflected signals of the reference pulsed doppler signal, an angle with respect to the axis representing the frequency of reflected signals of the reference pulsed doppler signal, and a vector displaced 180 degrees from the axis, the vector representing a Nyquist limit of the reference pulsed doppler signal. The colors on the plot in a positive direction at a maximum amplitude for a first frequency towards a point representing maximum amplitude for a second frequency range from a first color to a second color, colors on the plot in a negative direction at a maximum amplitude for a third frequency towards a point for a maximum amplitude for a fourth frequency range from a third color to a fourth color, and the colors for each frequency on the plot range from the color at a maximum amplitude for each frequency to a fifth color at the origin.
