摘要：
The detection performance of coherent MIMO radar with orthogonal waveforms is compared to that of a radar using a directed beam. For an accelerating target and Doppler processing detection, an analytical expression for probability of detection which explicitly accounts for range-Doppler migration is presented. It is shown that radar and target parameters should satisfy particular conditions in order to ensure that range-Doppler migration does not occur. Due to longer integration times, MIMO radar suffers degraded detection performance compared to that of a directed beam radar. Doppler migration due to target acceleration is the dominant cause of range-Doppler migration as the number of antenna elements increases.
