Claim 33:
34. The instrument according to claim 33, where
said NPD are stored for a set of multiple image points, and
a new set of at least two LF and HF pulse complexes are transmitted along a new set of HF transmit beams through said set of multiple image points, and
recording for each pulse complex HF back-scatter receive signals with HF receive beams equal to each HF transmit beams, and
estimating from said stored NPDs a set of at least one of i) delay and ii) speckle/pulse form corrections, and correcting said HF back-scatter receive signals with said set of speckle/pulse form and/or delay corrections to produce corrected HF receive signals, and
combining said corrected HF signals to form one or both of i) linear HF back-scatter receive signals with suppression of multiple scattering noise, and ii) nonlinear HF back-scatter receive signals with strong suppression of linear scattering signals.
