Abstract :
An analysis of a digital moving target indicator (DMTI) using the traditional fast Fourier transform (FFT) and the recently developed nonlinear spectral estimation techniques is presented. The performance evaluation has been done using simulated target and clutter models in the presence of white Gaussian noise. MTI improvement factor has been computed for all the cases, and it clearly shows the superiority of the nonlinear spectral estimation methods, especially for short data lengths
