Abstract
A method includes correlating a plurality of samples of a waveform into a correlation domain to provide a mainlobe defined by a first subset of a plurality of pulse-compressed samples and a plurality of sidelobes defined by a second subset of the plurality of pulse-compressed samples. A weight is calculated for at least one of the pulse-compressed samples, and one of a plurality of SVA filter values is selected to apply to the at least one pulse-compressed sample based on the calculated weight of the at least one pulse-compressed sample. The SVA filter values include one, one minus a quotient of one-half divided by the calculated weight of the at least one sample, and a scale factor having a value greater than zero and less than or equal to one. The selected SVA filter values are applied to the at least one pulse-compressed sample.
