这段我翻译过了，谁能帮忙翻译下我好做个参照： 如果觉得汉语不妥，也可以帮我修改哈。。。 没找到版规，不知道一日发两贴会不会被扣金币呀。。。 MIMO雷达是将多输入多输出技术应用于雷达系统，在传统的相控阵雷达基础上发展起来的一种新型雷达。目前MIMO雷达有两种模型：美国麻省理工学院林肯实验室提出的发射分集MIMO雷达模型，贝尔实验室提出的统计MIMO雷达模型。发射分集的MIMO雷达是在发射端由阵元(或子阵)全向发射相互正交的波形，回波信号为所有信号的延迟和;在接收端，用匹配滤波器组来分离回波信号中的各发射分量，然后通过DBF技术来形成接收波束和等效发射波束。和传统的相控阵雷达性比较MIMO雷达提高了雷达抗截获性能和在高杂波背景中探测低速目标的能力，改善强杂波背景中检测弱目标的能力。 在MIMO雷达系统中上述性能的改善主要得益于其独特的波束形成方式和正交波形的采用，以及由此带来的更加灵活的信号处理方式。 |

MIMO radar is a new kind of radar that used multi-input and multi-output technology, it developed on the basis of traditional phase array radar. There are two models of the MIMO radar now: the transmit diversity MIMO radar model that proposed by Massachusetts Institute of Technology's Lincoln Laboratory, the statistical MIMO radar model that proposed by Bell Labs. The transmit diversity MIMO radar launches mutually orthogonal wave from the transmitter's array element(or sub-array) to all directions, echo signal is the sum of all signals' delay; at the receiver, it use matched filter to separate every emission in echo wave signal, then use DBF technology to form receiving beam and equivalent emission beam. Comparing to the traditional radar, the MIMO radar have improved the anti-interception performance and the detect low speed targets ability in high-clutter background, it also improved the detect weak target ability in high-clutter. The improvements that just mentioned in the MIMO radar system are mainly because of the special way that the beam formed and the usage of the mutually orthogonal wave, also because it bring us more flexible signal processing way. |
