The invention pertains to Doppler radar systems for tracking targets in high Start Printed Page 12597clutter. A processor mitigates a clutter cloud in a reflected radar signal, the clutter cloud having a velocity growth rate. The processor includes an input for receiving a reflected radar signal, a delay line having a plurality of moving target indicator (MTI) Doppler filters, and an output connected in circuit with the plurality of MTI Doppler filters. The delay line covers a Doppler frequency range corresponding to the velocity growth rate of the clutter cloud. The reflected radar signal passes through the delay line to mitigate a portion of the reflected radar signal that is reflected by the clutter cloud from the reflected radar signal.
