Measuring the Operational Effectiveness of Search and Screening Sensors from Exercise Data

At present, methods are well established for measuring the performance of sensors, such as sonars and radars, in an experimental environment. However, the results of these measurements are not necessarily indicative of the sensors' performance under operational conditions. A method is developed, whereby, the operational effectiveness of sensors is determined directly from data obtained from operational exercises. The sensor performance is represented by a lateral range curve called the modified definite range law. Planning errors are discussed and detailed procedures and forms are recommended.
