| Description | We report on a W-band frequency-modulated continuous-wave (FMCW) radar module with fractional bandwidth over 10 %. To improve flatness over large operation bandwidth, the radar module is developed with focus on the 90–101 GHz modular transceiver, for which accurate modeling of Schottky diode in combination with an integrated design method are proposed in this work. Moreover, the nonlinearity compensation approach is introduced to further optimize the range resolution. To verify the design method and RF performance of the radar module, both measurements of critical components and ISAR imaging experiments are performed. The results demonstrate that high resolution in range and azimuth dimensions can be achieved based on the radar module, of which the receiving gain flatness and transmitting power flatness are better than ±1.3 dB and ±0.7 dB over 90~101 GHz, respectively. |
