Original Kurzfassung:
For radar sensors, for example, automotive radar sensors based on integrated circuits, taking advantage of the growing capabilities of digital circuits is becoming of increasing interest. Currently used linear frequency-modulated continuous wave (FMCW) signals could be replaced with phase-coded ones. As a consequence, the codes used would become a significant design parameter. In our investigation, we applied three binary codes (binary m-sequence, almost perfect autocorrelation
sequence, and Golay-complementary sequence), one two-valued code (Golomb's code), and one ternary sequence (Ipatov's ternary sequence) and used a linear FMCW signal for comparison. The codes were selected with a future realization of the radar system based on integrated circuits in mind. We provide brief instructions for generating each sequence. Finally, we demonstrate the performance of the phase-coded signals by means of measurements carried out with a SiGe-based RF IQ-transceiver.
