Signal processor for narrow band sonar signals |
摘要 |
A digital signal processor wherein a bit stream containing correlation information for a large sample size is converted into several basic correlation functions, each of which covers a small number of samples within the large input sample. Each basic correlation function is examined to determine whether it contains a valid sonar signal, and the original bit stream is then integrated over those time periods for which the corresponding basic correlation functions indicate the presence of a valid sonar signal. The resulting optimized digital correlation function is converted into an analog signal.
