杂波加噪声环境下MIMO雷达检测性能分析①

摘要

MIMO 雷达采用空间分集和波形分集技术，使其在目标检测等方面与传统雷达相比有明显的优势，逐渐成为了一个未来雷达方向的研究热点。本文在杂波与自身噪声都存在的条件下，给出了MIMO雷达检测模型，导出检测性能的理论公式，并且在多脉冲积累的条件下与相控阵雷达做仿真比较，得出当信噪比大于10dB 时， MIMO雷达有着明显的优势。%MIMO radar has obvious advantage of the target detection performance compared with the traditional radar by using space diversity and waveform diversity technology, and becomes a research hot spot of future radar. In this paper, author gives the MIMO radar detection model based on the condition of clutter and noise, and deduces the theoretical formula of the detection performance. Its detection performance is compared with phased array radar under the multiple pulse accumulation conditions. The simulation result shows that when the SNR more than 10 dB, MIMO radar has obvious advantages.
