Abstract

This paper studies signal cancellation effects in adaptive radar. Using examples from Mountaintop data, it is shown that signal cancellation occurs when the target of interest is included in the weight vector training. The signal cancellation is due to calibration errors (mismatch between the target signal and presumed steering vector). An eigenanalysis-based adaptive beamformer is shown to have greater robustness to signal cancellation effects than the sample matrix inversion (SMI) method.
