| 摘 要： | 本文研究了多输入多输出(MIMO)雷达系统波束形成和单脉冲测角问题。MIMO雷达利用分集技术,在发射端全向发射正交波形,在接收端利用DBF技术同时形成多个波束。本文推导不同接收方式下MIMO雷达波束的方向图函数,给出其半功率波束宽度计算公式。将数字单脉冲测角技术应用于MIMO雷达,通过不同布阵对测角精度进行分析,并与相控阵雷达测角性能进行比较。计算机仿真结果表明,在相同阵列情况下,MIMO雷达测角性能优于传统相控阵雷达。

| Abstract: | Beamforming and monopulse angle measurement for multiple input multiple output(MIMO) radar system is discussed.Through application of space diversity technology in MIMO radar,orthogonal waveforms are transmitted omnidirectionally;and by using digital beam forming(DBF) technology in the receiver,multi-beam are formed simultaneously.Pattern function of MIMO radar beam in different receive ways is deduced;and the computing formulas of 3-dB beam-width are presented.Through application of digital monopulse angle... |
