The implementation of Zero Doppler Filter in Radar applications can be simplified to cause a substantial saving of computational time when an associated Moving Target Indicator MTI filter is computed. Because the zero doppler filter is actually the MTI Filter shifted 180 degrees in the phase domain, the Zero Doppler output of the filter can be derived from the MTI output.
