论文摘要
目标检测是多输入多输出（MIMO）雷达的重要问题。提出了许多现有的目标检测算法，而无需考虑由模数转换器（ADC）引起的量化误差。本文通过一位ADC解决了MIMO雷达的目标检测问题，并得出了基于RAO的基于测试的检测器。所提出的方法具有几个吸引人的特征：1）它是封闭形式的检测器； 2）它允许我们直接处理符号测量； 3）检测器的分布有封闭形式的近似值，这使我们可以从理论上评估其性能。此外，封闭形式的分布使我们能够研究由于一位ADC而导致的性能降解，而低信号到噪声差异（SNR）的损失约为$ 2 $ dB，而$ \ ynofty $ bit ADC则产生了大约2美元的损失。包括仿真结果以展示提出的检测器的优势并验证理论结果的准确性。
Target detection is an important problem in multiple-input multiple-output (MIMO) radar. Many existing target detection algorithms were proposed without taking into consideration the quantization error caused by analog-to-digital converters (ADCs). This paper addresses the problem of target detection for MIMO radar with one-bit ADCs and derives a Rao's test-based detector. The proposed method has several appealing features: 1) it is a closed-form detector; 2) it allows us to handle sign measurements straightforwardly; 3) there are closed-form approximations of the detector's distributions, which allow us to theoretically evaluate its performance. Moreover, the closed-form distributions allow us to study the performance degradation due to the one-bit ADCs, yielding an approximate $2$ dB loss in the low-signal-to-noise-ratio (SNR) regime compared to $\infty$-bit ADCs. Simulation results are included to showcase the advantage of the proposed detector and validate the accuracy of the theoretical results.
