Abstract :
An improved frequency domain approach for quadrature detector of LFM signal is presented. An enhanced signal processing flow for digital IF quadrature detector is given and analysis of image rejection ratio (IRR) of LFM signal for quadrature detector is discussed. Simulation results show that excellent IRR can be obtained as low as -300 dB with this approach.
