Abstract : In recent years, electromagnetic tactical decision aids have been developed to assess environmental effects on the performance of operational systems, such as shipboard radars. In general, these systems have performed well and are now routinely used by operational forces to optimize their use of sensors and deployment of forces. In many cases, laboratory engineers have taken the existing tactical decision aid software and used it to assess the performance of proposed new sensors. Since the original software was not designed for this purpose, many deficiencies in such a use were soon identified. For example, most engineers prefer to graphically compare performance results as a single design parameter, such as radar pulse length, is varied over a range of possible values. Also, in designing a new system, one is usually more interested in the long-term statistical performance than in single-event performance that the tactical decision aids are normally designed to assess.
