Abstract:
1. A method for processing a received radar pulse from a moving target, comprising: a) receiving a return signal; b) obtaining L+(2M−1 (N−1) samples y of the return signal, where y(Λ)={tilde over (x)} c) applying Minimum Mean Square Error (MMSE) estimation to each successive N samples to obtain initial impulse response estimates [{circumflex over (x)} d) computing power estimates {circumflex over (ρ)} e) estimating a range cell Doppler shift for each range cell magnitude estimate above a user-selected threshold; f) computing MMSE filters according to w(Λ)=ρ(Λ)({tilde over (C)}(Λ)+R) g) applying the MMSE filters to y to obtain [{circumflex over (x)} h) repeating (e)-(g) for subsequent reiterative stages until a desired length−L range window is reached, thereby resolving the scatterers from noise and other scatterers.
