Common orthogonal frequency-division multiplexing (OFDM)-based radar waveforms normally require high sampling rates if a good range resolution shall be achieved. In contrast, this article proposes a scheme that keeps the necessary sampling rates at t

Large-scale antenna arrays operating in the millimetre-wave (mmW) regime are required for mobile radio base stations of the next generation. These arrays should support dual-polarization and cover the large available bandwidths. Two dual-polarized an

Distance measurement tasks in micromachine tools need to be performed with micrometer accuracy. For such tasks, frequency-modulated continuous-wave (FMCW) radars with a combination of frequency and phase evaluations are a good choice. However, the ac
