Summary: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
