Improvement of range resolution of FMCW autodyne radar

The principals of range resolution improvement the self-mixing FMCW radar based on analysis of the spectrum of high-order harmonics of intermediate frequency is proposed. Developed the scheme and investigated the model of Ka-band surveillance self-mixing FMCW radar with digital control and spectral processing of receiving signal. Advantages of this radar are small size, low power consumption and use of scanning antenna.
