Claim 21:
22. The method of claim 20, wherein, further comprising:
providing a selected one of a second amplitude-modulation (AM) signal in said AM mode and a second chirp signal in said chirp mode using a second transmitter adapted to be coupled to said acoustic transducer;
receiving a second digital received signal using a second receiver adapted to be coupled to said acoustic transducer;
during said first measurement period:
placing said second transmitter into said one of said AM mode and said chirp mode using said second channel;
selectively detecting a third direct echo in said second channel of said second digital received signal of said one of said AM signal and said chirp signal; and
selectively detecting a third indirect echo in said second channel of said second digital received signal of said one of said AM signal and said chirp signal, and

during said second measurement period:
placing said second transmitter into said other one of said AM mode and said chirp mode using said second channel;
selectively detecting a fourth direct echo in said second channel of said second digital received signal of said other one of said AM signal and said chirp signal; and
selectively detecting a fourth indirect echo in said second channel of said digital received signal of said one of said AM signal and said chirp signal.
