A method for discriminating and tracking a target in a clutter cloud includes transmitting a radar signal at a signal bandwidth to: identify a range extent of a clutter cloud; determine a centroid and a velocity growth rate of the clutter cloud; and identify a direction of movement of the centroid of the clutter cloud. The method may also include locking a another radar signal having a greater signal bandwidth onto the centroid of the clutter cloud whereby the centroid is tracked within one radar range resolution bin; providing a delay line that includes...
What is claimed is: 1. A processor for mitigating a clutter cloud in a reflected radar signal, the clutter cloud having a velocity growth rate, the processor comprising: an input for receiving a reflected radar signal; a delay line comprising a plurality of moving target indicator (MTI) Doppler filters, the delay line being configured to cover a Doppler frequency range corresponding to the velocity growth rate of the clutter cloud, the reflected radar signal passing through the delay line to mitigate a portion of the reflected radar signal that is refle...
