Reuse of fractional waveform libraries for MIMO radar and electronic countermeasures

A fundamental aspect in the hardware-software design of modern radar systems, for example MIMO or Low Probability of Intercept Radar, is to operate in electromagnetically crowded environments. Proper radar waveform design is central to effective solutions in such systems. In this paper cross-interference and waveform reuse for a set of waveform libraries based on the fractional Fourier transform are presented and analysed. The results demonstrate the potential of the novel libraries in increasing the number of available waveforms and for stealth transmissions.
