fulfillment of the requirements considering limitations of radar state of 

 the art, schedules, and other factors germane to the problem of achieving 

 a useful operational capability for the overall weapons system. 



In actual practice, the design process is long enough and complicated 

 enough to justify subdivision of the two basic phases described. The next 

 paragraph will discuss the complete design cycle of a typical weapons 

 system development with particular emphasis on the role of the radar 

 designer as a vital part of the designers' team.
