Abstract
Abstract – The successful realisation of high performance radars requires sophisticated methods and algorithms capable of obtaining information about investigated objects.
This paper illustrates a new method to determine surface inhomogeneities and/or their shapes for centimetre, millimetre, and sub – millimetre waves based on a method for revealing structures (MRS) which is a powerful tool to analyse data by means of finding of spatial points in which signals have the greatest contrast concerning other background points.
Typical examples of such inhomogeneous (textured) areas are near-surface buried objects, snow-covered ground, water waves and many others.
The new suggested method was named as “BinREL” and can be considered a generic approach for advanced signal processing since it is not tied to the physical nature or a concrete form of probing signal.
The merits of the method has been evaluated by processing datasets obtained from Staal Technologies prototypes based on 60 GHz frequency modulated continuous wave (FMCW) radar application specific integrated circuit (ASIC): RIC60A. The inkjet - printed images were taken as an investigation example.
