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

Abstract

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 [1] , [2] , [3] , [4] , [5] , [6] , [7] , [8] and upconverted radar systems [9] , [10] . 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.
