Abstract
In this paper, we propose and experiment with a dual-functional system that can simultaneously implement vector signal generation and radar detection based on frequency quadrupling. In the experimental demonstration, a generated W-band quadrature-phase-shift-keying (QPSK) vector signal is transmitted wirelessly over 1 m with a bit-error rate (BER) below 3.8 × 10-3. A radar working in the W band is investigated with a range resolution of 0.94 cm. To the best of our knowledge, this is the first time that simultaneous QPSK vector signal generation and radar detection in the W band has been realized.
