xii PREFACE 



Many of the authors have had previous association on team efforts aimed 

 at the development and production of complex airborne radar equipments. 

 The technical approaches presented thus represent tools forged on the 

 anvil of experience — tools which have facilitated the solution of many- 

 difficult problems. It is the authors' hope that succeeding generations of 

 system designers may use these tools to their advantage in designing the 

 even more complex systems to come. 



Acknowledgments 



In addition to the authors, there are many individuals and organizations 

 to whom acknowledgment must be made for an active part in the writing 

 of this book. Members of the Naval Research Laboratories, the Naval 

 Air Development Center, the Fairchild Astrionics Division and the West- 

 inghouse Electric Corporation assisted with suggestions, criticisms, a.nd 

 technical readings. Deepest thanks must be extended to the government 

 laboratories (NRL and WADC) and the corporations (Barnes Engineering, 

 Bendix Aviation, General Precision Laboratory, Raytheon Manufacturing, 

 Varian Associates, and Westinghouse Electric) who provided encourage- 

 ment and assistance to the contributors. 



The assistance of Mr. R. G. Clanton of Westinghouse was vital to the 

 preparation of the examples employed in Chapter 2. In addition, Mr. 

 Clanton's many helpful suggestions and detailed reviews of the remainder 

 of this chapter are most gratefully acknowledged. Mr. R. H. Laprade 

 had the responsibility of reviewing all the material relating to propagation 

 in addition to his contribution to Chapter 14. 



Mr. A. Stanley Higgins, Mr. Melvyn Goetz and Dr. J. F. Miner of West- 

 inghouse rendered invaluable services in overseeing the myriad details in- 

 volved in the editing and production of the final text. The Westinghouse 

 Electric Corporation deserves special thanks for the assistance provided on 

 drawings, typing, and the reproduction of the many drafts of the manu- 

 scripts.
