  • 摘要: 針對(duì)干擾條件下MIMO雷達(dá)面臨的信號(hào)截獲以及干擾源快速移動(dòng)等問(wèn)題，對(duì)雷達(dá)收發(fā)方向圖進(jìn)行優(yōu)化設(shè)計(jì)。在發(fā)射端利用最小積分旁瓣準(zhǔn)則對(duì)發(fā)射波束矩陣進(jìn)行優(yōu)化，將發(fā)射信號(hào)能量集中到目標(biāo)空域，降低旁瓣并在干擾方向形成發(fā)射零陷；在接收端利用廣義對(duì)角加載方法優(yōu)化接收方向圖，在提高信號(hào)接收穩(wěn)健性的同時(shí)展寬零陷。通過(guò)對(duì)MIMO雷達(dá)收發(fā)方向圖進(jìn)行聯(lián)合優(yōu)化設(shè)計(jì)，解決了信號(hào)被截獲及快速移動(dòng)的有源干擾等問(wèn)題，從收發(fā)兩端共同提高雷達(dá)整體性能。通過(guò)實(shí)驗(yàn)仿真對(duì)比分析，驗(yàn)證了所提方法的可行性和有效性。
    Abstract: For the problem of signal interception and fast moving jammers in MIMO radar application, this paper designs a new transmit beampattern through optimizing the transmit beamforming matrix based on the minimization of integrated-sidelobe. This new transmit beampattern can not only focus the transmit energy on the desired spatial sector but decrease the level of sidelobe as well as form a nulling at the jammers direction with the prior knowledge. At the receiving, a new robust beamforming method based on non-uniform generalized diagonal loading is proposed, which can strengthen the robustness of receiving beamformer against different errors and broaden the nulling adaptively. Through the optimization of joint transmit and receive beampattern for MIMO radar, the interception of signal and fast moving jamming are addressed, which improve the performance of MIMO radar from both transmitting and receiving. Simulation results and comparisons with existing methods demonstrate the feasibility and effectiveness of the proposed methods.
