Evaluation of Normalization of AN/SQS-26 ODT Channel.

Abstract

This technical note describes an evaluation of two schemes for normalizing the output of the AN/SQS-26 ODT channel. The two techniques under consideration are described and are referred to as a mean-divider and a norm device, respectively. For this study, the ODT processor is preceded by a perfect AGC, which results in the input to the processor having a fixed level and a bandwidth which varies with reverberation-to-noise ratio, R/N. Sets of interference were generated from an interference model for specified R/N. The interference spectrum varied from set to set as a function of R/N. However, time variations in the interference spectrum were not considered in this study. It is shown that the rate of exceeding threshold as a function of threshold varies with R/N at the output of the mean-divider. This lack of normalization indicates that, for the ODT processor, no further investigation of the device is warranted.
