Abstract :
The flexibility of a phased array radar together with the decoupling of the search and tracking functions means that there are many more operating parameters compared with conventional track-while-scan radars. Decisions on the values of these parameters have to be made both at the design stage and in a changing operational situation. It is shown that the optimum choice of parameter values can be made which will ensure the achievement of a specified search performance for minimum mean power. The process of optimisation gives rise to powerful design concepts which can also be applied to adaptive radar management in the operational situation. Without a proper basis for the choice of parameters values, both at the design and operating stages, a significantly suboptimal search performance is likely
