  • 摘要: 該文提出一種約束基波束權(quán)值動態(tài)的MIMO雷達(dá)發(fā)射波形設(shè)計(jì)方法。首先，構(gòu)造一組發(fā)射波形集并從理論上推導(dǎo)了陣元發(fā)射波形的恒模特性，在此基礎(chǔ)之上，將各陣元平均發(fā)射功率的均勻性控制問題轉(zhuǎn)化為基波束權(quán)值動態(tài)的定量約束問題；其次，建立了直接約束權(quán)值動態(tài)的基波束優(yōu)化模型，利用切線投影法和區(qū)域迭代法將其進(jìn)行凸松弛，并且給出了二階錐規(guī)劃子問題和序列錐迭代流程；最后，利用二階錐規(guī)劃設(shè)計(jì)出了基波束的比例系數(shù)。所提方法在保證MIMO雷達(dá)發(fā)射方向圖匹配性能的前提下，能夠兼顧陣元發(fā)射功率均勻性和發(fā)射方向圖旁瓣功率的性能，因而在設(shè)計(jì)發(fā)射波形時更具靈活性。仿真實(shí)驗(yàn)驗(yàn)證了所提方法的有效性。
    Abstract: A method for the design of transmit waveform of MIMO radar based on the dynamic range constraint in weight amplitude of basic beam is proposed. Firstly, a set of the transmit waveforms is constructed which can fulfill constant-modulus constraints. Further, the control of the difference between different elemental average transmit power is converted into the optimal of the weights dynamic of basic beam. Whats more, a pattern synthesis of the basic beam with the constraint of weight amplitude dynamic range based on the sequential cone program is proposed. The optimal model can be slack as a series sub-convex optimization problem. And the second order cone program of the sub-convex and its iteration technique based on the sequential cone program is given subsequently. Lastly, the weighted coefficients of basic beam of transmit beampattern is computed via second order cone program. The efficiency and validity are verified by the simulation results．
