Abstract

High speed ADCs are considered more and more by ADC manufacturers. The aim of such components is that they are to be used in applications such as high speed data acquisition devices, digital oscilloscopes, digital RF/IF signal processing, digital RF down conversion... The application we target in this research is the last one, digital RF down conversion, by the use of a high speed ADC (8 bits – 1 GSPS) in a radar receiver. In this article, we present a brief comparison between two kinds of radar receiver architectures : the superheterodyne and the expected one. We also present the method to characterise the ADC working in radar mode and the conclusion of the research.
