Close-In Dynamic Range Considerations in Upconverted and Frequency-Multiplied Frequency-Modulated Continuous-Wave Radars at Ku-Band: Close-In Dynamic Range Considerations in FMCW Radars

As silicon radars have become commonplace at microwave and millimeter-wave frequencies driven by automotive and other sensing applications, two specific architectures for these radars have become dominant in the literature: frequency-multiplied radar systems

. While both architectures are well reported, the literature in microwave theory and technology thus far does not offer a robust quantitative comparison of the two approaches regarding their radar behavior, especially in the case of dynamic range.
