The analysis of SFCW radar sensors is presented in this chapter. Specifically, it addresses the system’s important parameters including transmitted and received signals, down-converted I and Q signals, synthetic pulse, angle and range resolutions, frequency step, number of frequency steps, total bandwidth, range or penetration depth, range accuracy, range ambiguity, pulse repetition interval, dynamic range, and system performance factor. Maximum ranges or penetration depths in sensing multi-layer and buried targets are also discussed. The presented materials, although concise, should provide sufficient information for RF engineers to undertake the analysis of their own SFCW radar sensors and help design these sensors for sensing applications. |
