Abstract

We propose a double-modulated frequency modulation waveform for multiple-input multiple-output radars. The transmitted waveforms are divided into two segments with the same bandwidth and different durations. The durations of all the segments among different waveforms are used to optimize the performance. Theoretical analyses are provided to study the relationships between the autocorrelation/cross-correlation functions and parameters such as bandwidth, pulse duration, and segment durations. Numerical results show that the proposed waveform has low cross correlation even with Doppler shifts. The autocorrelation sidelobes, cross-correlation levels, and range sidelobes of the proposed waveform reduce with the increase in the time-bandwidth product.
