AN/SQS-26 Analysis Progress Report. June 1, 1965.

Abstract

The effect of target aspect on the performance of a linear correlator is being studied. Sea data tapes recorded under similar conditions except with the target in varying aspect are on hand. This data will be analyzed to yield several points on the signal processing gain curve for each target aspect. These curves will be compared to determine the effect of target aspect on target strength as seen by a linear correlator one hundred cps FM slide of one-half second duration. The properties of reverberation in surface channel and convergence zone mode are being studied. TRACOR has a set of tapes of CW echo cycles taken with no target present at various depression angles and various relative bearings. This data will be analyzed to study the properties of reverberation in convergence zone and surface channel modes. Also for a typical echo cycle power spectra will be computed at various times in the cycle. This will be used to obtain a 'feel' for the meaning of some of the parameters in reverberation analysis and to possibly improve the reverberation analysis method as a tool.
