In this paper, the development of the matrix-pencil technique is presented, including a historical overview and recent generalizations. It has been shown that this method is computationally efficient and robust to noise. A band-pass version of this approach has been implemented in hardware utilizing an AT&T DSP32C chip, to perform real-time target identification.
