Measurement for radar target identification using short-time matrix pencil method

This paper presents the measurement for radar target identification using a short-time matrix pencil method. Our measurement setup is done in an anechoic chamber to absorb reflections of other electromagnetic waves. Two different target shapes are used to examine the identification. In our measurement, a vector network analyzer is employed to measure the scattering response in term of S21. The scattering response in frequency domain is converted to that in time domain by using the inverse Fourier transform. The short-time matrix pencil method is applied to extract poles from the late-time portion of the scattered transient response. These poles are used to identify the targets. Measurement results show the potential practical application of radar target identification using a short-time matrix pencil method.
