A down-conversion method for attenuation of leakage signal in FMCW radar

This paper proposes a new down-conversion method to attenuate leakage signal in frequency modulated continuous wave (FMCW) radar. The proposed method reduces the effect of phase noise in the leakage signal. It can be simply realized through digital signal processing without additional hardware. Spec...

Summary:This paper proposes a new down-conversion method to attenuate leakage signal in frequency modulated continuous wave (FMCW) radar. The proposed method reduces the effect of phase noise in the leakage signal. It can be simply realized through digital signal processing without additional hardware. Specifications of practical FMCW radar and the phase noise which is bad enough were assumed and simulations in these conditions were performed. Power spectral density (PSD) results show that while a target signal is buried by the phase noise tail of the leakage signal, the proposed method detects the target signal by attenuating the tail.
