A brief review of Doppler sonar development at Scripps

Development of acoustic techniques for the remote sensing of ocean velocity has been ongoing at Scripps for the past 42 years. While many scientifically productive systems have been created, there have also been technical surprises and dead-ends. Here the development of both pulse-to-pulse coherent and incoherent backscatter systems at SIO is reviewed, with an emphasis on the real-world problems encountered.
