Frequency-domain Based Waveform Design for Binary Extended-target Classification

In this paper, an optimal radar waveform-design scheme is proposed, using frequency snapshots (i.e., frequency-domain processing), based on an objective function derived directly from a binary classification/identification criterion constrained by waveform-energy. We consider an extended-target model where the targets frequency response is assumed to be complex Gaussian. High- and low-energy solutions for the optimal waveform are explored and closed-form expressions in both the scenarios are derived.
