The parametric matched filter (PMF) and the vector autoregressive (VAR) temporally-whitening filter are analyzed. The results show that the coefficients of the PMF obtained by minimizing mean square error (MSE) estimated via sum of squared errors (SSE) are equivalent to those of the VAR filter by multichannel least square (LS) algorithm of the same order. Additionally, the asymptotic performance of the LS estimator of VAR filter is analyzed. Finally, the operations and performances for clutter suppression are analyzed.
