Abstract

This paper pertains to the design aspects of a multifrequency FMCW/SFCW radar with emphasis on the engineering problems involved in its implementation. The paper mostly discusses the FMCW mode of operation. This system can also be used for generating SFCW signals. The implications in this mode are also examined. In the FMCW mode, this radar generates 8 separate FMCW signals which are then additively mixed and radiated. The target return also comprises returns at these frequencies. The signals are then split into their constituents and processed collectively to obtain an extremely high resolution synthetic image of the target. This paper discusses the philosophy which went into the implementation of this radar followed by an analysis of the range resolution capability of this system. It then discusses the ambiguity function one obtains for this type of radar, its advantages and disadvantages
