This paper demonstrates the closed-loop, adaptive-waveform approach applied to high-fidelity target model signatures generated by [XFdtd](https://www.remcom.com/xfdtd-3d-em-simulation-software). The radar equation is incorporated into the authors' models for use in the waveform design procedure. Because SNR varies with range, so do the optimized waveforms for target recognition. Constant-modulus waveform constraints are enforced, and a template-based classification strategy is used.
