weight coefficients, Doppler filter, filtering, amplitude-phase characteristic, side lobe


A formula for computing the optimal values of weight coefficients of coherent integration of reflections has been proposed for minimizing the sidelobe level of amplitude-phase characteristics (APC) of Doppler filters applicable at an arbitrary number of such filters. The AFC plots of Doppler filters were calculated and presented for the case of coherent integrator for 8, 12, 16, 24, 32 and 36 filters. The estimated average sidelobe level indicated the validity of specified proposals.
