FM Noise Waveforms Optimized According to a Temporal Template Error (TTE) Metric

It has recently been shown that a form of pulse agility involving FM noise waveforms provides tremendous flexibility and design freedom to realize physical emissions for multiple different radar applications. The design of such waveforms tends to involve random initialization followed by optimization according to the error between a waveform's spectral content and a desired frequency-domain template. In contrast, here the spectral envelope is fixed and the optimization relies on the error relative to a desired temporal template (e.g. a constant amplitude pulse). It is demonstrated in simulation as well as experimentally in loopback that this temporal template error (TTE) approach provides sidelobe and spectral containment performance that is generally superior to previous frequency template forms and other FM noise design schemes.
