Claim 11:
12. The method according to claim 11, where
for each selected group of HF transmit beams one uses HF receive beams equal to the HF transmit beams to receive at least two HF back-scatter receive signals from transmitted pulse complexes with different LF pulses, and
correcting said at least two HF back-scatter receive signals with at least one of i) an estimated NPD and ii) and estimated pulse form and speckle distortion, to provide at least two corrected HF back-scatter receive signals, and
combining said at least two corrected HF back-scatter receive signals to provide HF noise suppressed back-scatter receive signals with suppression of multiple scattering noise.
