Design and Generation of Stochastically Defined, Pulsed FM Noise Waveforms

The design and physical generation of diverse radar emissions often requires optimization of unique waveforms on an individual basis. Consequently, a significant processing overhead is incurred that could make real-time implementation impractical. To address this limitation, families of pulsed FM noise waveforms are defined here according to a parameterized process denoted as Stochastic Waveform Generation (StoWGe). Through the use of expectation metrics and an expected frequency template error (EFTE) cost function a particular waveform family is specified via a desired spectral shape so that each physical FM waveform can be easily produced by drawing samples from a random process. Performance is assessed via simulation and experimentally in loopback and open-air testing.
