D. Mauuary et al., FAST AMBIGUITY PROCESSING IN SOFAR PROPAGATION INVOLVING PERIODIC SIGNALS AND M SEQUENCES, IEEE transactions on signal processing, 46(8), 1998, pp. 2225-2230
Fast ambiguity processing on be used in active time delay and Doppler
identification in the sound fixing and ranging (SOFAR) propagation con
text. They need periodic signals generated from pseudorandom M sequenc
es. In the particular case of the SOFAR, the range of the observed Dop
pler effect enables use of the fastest version, provided that the peri
odicity of the signal is correctly adjusted.
