Circuitry and technological aspects of frequency synthesizers design for modern radars

Different aspects and results of the development of multifunctional frequency synthesizers for coherent airborne radar systems of high detection characteristics are presented. The practical recommendations as to a circuitry choice, component base, design and production technology of synthesizers under consideration are given. The key element of advanced coherent radar is multifunctional frequency synthesizer (FS) forming the nomenclature of intercoherent signals, the main parameter of synthesizers are used to determine the characteristics of radar detection and its noise immunity. Thus the development of FS design is made by certain guided principles and considerations.
