Interpretation Example

The direct output of the radar processing is the mean

range-doppler map. It is the result of 2D FFT over all

ranges and all speeds.

The following example demonstrates a road situation.

In the following figure, the range-doppler map on the

left side shows the speed and the distance of the ob-

jects. Zero speed is placed in the middle of the x-axis.

The distance is increasing on the y-axis. Negative

speeds (approaching objects) are shown to the left of

zero speed and positive speeds (receding objects)

are shown to the right of zero speed.

The blue and the black cars are driving away from the

radar and the white car is approaching. The blue car

is driving twice as fast as the black car.
