Abstract:
1. A method for processing a received, modulated pulse that requires predictive deconvolution to resolve a scatterer from noise and other scatterers, comprising: a) receiving a return signal; b) obtaining L+(2M−1)(N−1) samples y of the return signal, where y(l)={tilde over (x)} c) applying RMMSE estimation to each successive N samples to obtain initial impulse response estimates [{circumflex over (x)} d) computing power estimates {circumflex over (ρ)}(l)=|{circumflex over (x)} (e) computing MMSE filters according to w(l)=ρ(l) (C(l) R) (f) applying the MMSE filters to y to obtain [{circumflex over (x)} (g) repeating (d)–(f) for subsequent reiterative stages until a desired length-L range window is reached, thereby resolving the scatterer from noise and other scatterers.
