Traditional image processing is a typical twodimensionalsignalprocessing. The image data fusion belongs to this area as well.

To cope with the time varying and Doppler broadened clutter in airborne phased array radars, it is required that the signalprocessing be adaptive and twodimensional (spatial and temporal).
Using two-dimensionalsignal vectors, the process of Doppler shift modulation and demodulation is analyzed, and a signal processing method for extracting flow speed information is derived.
