Long Range Upgrading of the AN/SQS-26.
Abstract
A major portion of this report concerns echo energy splitting. Actual sea echoes are energy-split to varying degrees, therefore, echo energy splitting presents a problem of realism in computer simulations. More realistic simulations will be required as more subtle differences between processors are investigated. Echo energy splitting also presents a challenge to processor design. One method of nullifying the effects of energy splitting, adaptive recombination, was investigated. Because the correlation process results in a time compression, the output of a correlator is particularly amenable to normalization procedures. This characteristic of correlation permits an effective normalization technique to be employed in a computer program. An investigation was also made of the application of advanced signal processing techniques to enhance signal-to-noise ratio prior to the SSI display. The problems relating to the AN/SQS-26(BX) are illustrative of both the usefulness of simulation techniques in performance evaluation and the need of extending testing instrumentation as more subtle problems are encountered.
