Orthogonal Waveforms for High Resolution Range-Doppler Target Reflectivity Estimation
The wideband received signal as the affine group Fourier transform of the range-Doppler wideband target reflectivity function evaluated at the transmitted waveform has been described. The approach provides to a framework in which the high resolution target reflectivity function estimation and waveform design problems are jointly addressed. A Wiener filtering method in the Fourier transform of the affine group to suppress clutter has been developed. Then, that Wiener filter use to precondition the transmitted waveforms to reject clutter has been shown. When, only N waveforms are to be transmitted, the optimal waveforms in the MMSE sense becomes the eigenfunctions of the modified Wiener filter corresponding to the largest N eigenvalues.
