Robust Beamforming with Phase Response Fixed and Magnitude Response Constraint

  • 摘要: 傳統(tǒng)的幅度約束波束形成器是一個(gè)非凸問(wèn)題,需將原始模型化為線性規(guī)劃進(jìn)行間接求解。該文針對(duì)均勻線陣提出一種相位響應(yīng)固定幅度響應(yīng)約束(PFMC)的穩(wěn)健波束形成方法。利用權(quán)矢量逆序列對(duì)應(yīng)的傳遞函數(shù)與陣列響應(yīng)函數(shù)只差一個(gè)相位因子這一性質(zhì),將陣列響應(yīng)的相位設(shè)置為固定的線性相位,僅對(duì)陣列響應(yīng)的實(shí)數(shù)幅度進(jìn)行約束,從而得到一個(gè)凸的代價(jià)函數(shù),最優(yōu)權(quán)矢量可以利用內(nèi)點(diǎn)法求出。同時(shí)考慮到協(xié)方差矩陣誤差,利用最壞(WC)情況性能最優(yōu)原理提出PFMC-WC算法改善PFMC的性能。與傳統(tǒng)幅度約束波束形成器相比,減少了約束個(gè)數(shù)并省掉了恢復(fù)權(quán)矢量過(guò)程,從而降低了計(jì)算量。此外,由于相位響應(yīng)得到保證,該文算法相對(duì)于傳統(tǒng)算法具有更好的性能。仿真實(shí)驗(yàn)驗(yàn)證了該文算法的有效性。
