not bear any relation to a presently realizable radar system. The purpose of 

 this analysis is to define the radar problem solely as it is dictated by the 

 weapons system problem. Whether the radar problem thus defined is 

 technically reasonable for a given era is determined in the next major 

 step of the design process. 



Problem Solution. The systems analysis defined the required radar 

 performance. Now, the designer must attempt to solve the defined problem 

 by (1) hypothesizing a radar system of given general characteristics and 

 (2) examining the interrelationships between radar parameters and radar 

 performance. Typical examples of the interrelationships developed by 

 such a study are shown in Fig. l-22b for the case of a single radar param-

 for each radar parameter that exercises important influences on radar 

 performance.
