Abstract: This paper used the Half Fourier Transform to analyze various components of
a nonstationary signal. By MATLAB simulation, a practical example, remote
sensing a finite cylinder, was tested to verify the proposed algorithm. The
result showed that in the higher SNR, the proposed algorithm can perfectly
meet our expectation: to separate impulse like components from damped exponentials.

Key words: matrix pencil method, Gaussian pulse, damped sinusoid, half Fourier transform, matrix pencil method, Gaussian pulse, damped sinusoid
