摘要：
It is known that deploying low-resolution (e.g., one-bit) analog-to-digital converters (ADCs) at the receive antennas can reduce the hardware cost and circuit power consumption, especially for large-scale systems. In this context, we investigate the performance of target detection for collocated multiple-input multiple-output (MIMO) radar with one-bit ADCs. Considering a scenario where the transmit-receive channel matrix suffers from uncertainty with a known distribution, a one-bit likelihood ratio test (LRT) detector is derived. Moreover, the asymptotic performance of this detector is analyzed. Numerical simulations are performed to demonstrate our theoretical analysis and evaluate the performance of the one-bit LRT detecor.
