Angle-dependent range sidelobes of MIMO waveforms

MIMO radar systems offer potential in many applications and have been studied intensely in recent years. Waveform design is of particular interest because some applications require low cross-correlation between the waveforms emitted from different apertures. In this paper, we consider how multiple waveforms emitted and received by a linear MIMO array result in different effective waveforms as a function of array angle. For each effective waveform, there is a unique range autocorrelation function, which is the zero-Doppler cut of the ambiguity function. We derive some relationships related to this angle-dependent range ambiguity and demonstrate some simulated examples.
