This report contains the results of an investigation of two techniques of signal recombination. This work was directed at improving detection performance in high time-resolution signal processing systems such as the linear correlator. Such systems are susceptible to echo energy splitting and some improvement in detection performance can be expected if a suitable technique is available for recombining the energy in multiple arrivals. In this project, echoes recorded at sea and simulated multiple arrival echoes were analyzed. The results indicate that for these particular echoes, the detection performance of the linear correlator was improved by the signal recombination techniques considered. A further study of these techniques is recommended. Author
