Optimal waveform selection in range-Doppler imaging

Solves the problem of adaptively selecting a set of N radar waveforms to obtain the optimal L₂ estimate of a target range-Doppler reflectivity function. The authors assume that the targets correspond to one of two classes. They show that the waveform selection strategy involves an initial class identification phase followed by a pure imaging phase. They provide a recipe for minimizing the number of waveforms needed for the class identification phase. They show that this leads to an optimal adaptive target imaging strategy
