Doppler sensitivity of multiple-input multiple-output (MIMO) radar waveforms is complicated but rarely is of concern in most existing MIMO waveform designs. For both distributed and colocated MIMO radar, this paper studies the impact of Doppler sensitivity on both autocorrelation and mutual correlation sidelobes of both constant-modulus MIMO transmit waveforms and angular waveforms in theory and via...
Distributed radar sites needs a group of nearly-orthogonal waveforms and polyphase coded waveforms (PCWs) can approach the orthogonality in the code dimension. However, PCWs are sensitive to Doppler mismatch in range compression, which can induce signal-to-noise ratio (SNR) loss and sidelobe level increase. In this paper, we first study how to design a seed PCW with a high Doppler tolerance and then...
