An Adaptive Fast Fourier Transform Weighting Technique to Increase Small Target Sensitivity.
Abstract
A radar signal processor is described which operates without clutter canceller and AGC circuits by applying an adaptive weighting circuit which adjusts the FFT weighting function on a range gate basis to account for clutter in that range gate. An input buffer determines log to the base 2 values per range gate for use in the weighting operation and a normalization circuit scales the weighted FFT output to facilitate post-processing.
