摘要: 該文針對(duì)近場(chǎng)源的方向角和距離的二維參數(shù)估計(jì)，提出了一種新的近場(chǎng)源二維參數(shù)估計(jì)方法。該方法利用雙極化陣列的極化信息和二階統(tǒng)計(jì)量估計(jì)近場(chǎng)源的波達(dá)方向和距離參數(shù)。該方法具有估計(jì)精度高和無需譜峰搜索的優(yōu)點(diǎn)。仿真實(shí)驗(yàn)證明了該算法的有效性。

Abstract: The bearing and range estimation of near-field sources is studied and a new method is presented. The presented algorithm uses the dual-polarization array and second statistics to estimate DOA -range parameter of near-field sources. The method has the merits of good estimate precision and no needing spectral peak searching. Its effectiveness is approved by the simulation results. -
