【摘要】:對多輸入多輸出(multiple input multiple output,MIMO)雷達發(fā)射部分相關(guān)波形時,比幅單脈沖方法的角度測量性能進行了理論分析。通過建立MIMO雷達的一般信號模型,采用矩陣微分的方法對噪聲引起的比幅單脈沖左右波束輸出信號的起伏進行了統(tǒng)計分析,從而給出了部分相關(guān)MIMO雷達體制下比幅單脈沖方法的理論測角性能。由得出的結(jié)論可以直接得出正交MIMO雷達及相控陣雷達體制下比幅單脈沖方法的理論測角性能。通過數(shù)值仿真實驗對部分相關(guān)MIMO雷達下比幅單脈沖方法的性能進行了仿真分析,并驗證了理論分析的正確性。
[Abstract]:The angle measurement performance of the amplitude ratio monopulse method for multi-input multi-output (multiple input multiple output,MIMO) radar transmitting part correlation waveform is analyzed theoretically. By establishing the general signal model of MIMO radar, the fluctuation of the output signal caused by noise is analyzed by using matrix differential method. The theoretical angle measurement performance of monopulse method in partially correlated MIMO radar system is presented. The theoretical angle measurement performance of the monopulse method for orthogonal MIMO radar and phased array radar can be obtained directly from the conclusion. The performance of the amplitude-to-amplitude monopulse method in partially correlated MIMO radar is simulated by numerical simulation experiments, and the correctness of the theoretical analysis is verified.
