Some Notes on Sonar System AN/SQS-26 (XN-2) Sea Data Analysis.

Abstract

The work reported continues the effort documented in TIS R64EMH22 and TIS R64EMH32. Extensive computer processing of sea returns has consistently revealed serious performance anomalies when particular modulation types are employed. An attempt to explain such negative results is undertaken by means of a computer simulation of both the active sonar system and the environment in which the system operates. Various combinations of modulation types and environmental parameters are tested and the simulation results are compared with results obtained in actual sea return processing. The results obtained indicate that many of the anomalies observed in the processing of sea returns may be explained in terms of certain environmental or medium effects. It is further shown that a basic incompatibility can exist between modulation type and operating environment. Such mismatch can produce anomalies in the system displays and result in loss of detection capability. (Author)
