Practical Sequential Design Procedures for Submarine ASW Search Operational Testing: A Simulation Study
Abstract
The efficient design of a free play, 24 hour per day, operational test (OT) of an ASW search system remains a challenge to the OT community. It will often be the case during an ASW search OT that artificial means of detecting the target are introduced in order to speed up the detection process. When used, these various artificial means of speeding up the detection process severely affect the realism of the search OT and limit the usefulness of the collected data. However, if these artificial procedures are not used, the OTD is faced with the problem of controlling the average length of time that a test event lasts. This presentation will identify test control rules that an OTD can employ from onboard the searching platform to allow for an efficient, realistic, free play, 24 hour per day OT. The basic test control premise described here is to stop the test event if the time without a detection/classification grows too long. Furthermore, if this long period passes again without detection/classification, then the OTD uses a different search scenario in which the size of the area being searched is shrunk. This presentation will focus on the results obtained by simulating an ASW search OT in which test control rules were applied. The ramifications of the use of these various test control rules on the number of trials expected (for a given test duration), the test duration (for a given number of required trials), and on the quality of the estimates of search related measures of effectiveness will also be discussed.
