摘要

摘要: 該文針對分布式陣列相干信號單次快拍波達(dá)方向估計(jì)問題，提出一種基于狀態(tài)空間平衡法的1維波達(dá)角估計(jì)算法。該算法首先直接利用單快拍數(shù)據(jù)以分布式陣列每個子陣單元進(jìn)行Hankle矩陣構(gòu)造，然后采用狀態(tài)空間平衡法，分別獲得低精度無模糊的子陣單元內(nèi)DOA估計(jì)和高精度有模糊的子陣單元間DOA估計(jì)，最后結(jié)合配對和解模糊算法獲得高精度無模糊DOA估計(jì)。該算法不受信號形式限制，可同時對相干信號和非相干信號進(jìn)行處理，能充分利用分布式陣列擴(kuò)展陣列物理孔徑特性，獲得較高的DOA估計(jì)精度。計(jì)算機(jī)仿真結(jié)果驗(yàn)證了所提算法的有效性。

Abstract: An algorithm of Directions Of Arrival (DOA) estimation based on the state-space method is proposed to deal with the problem of estimating DOA of multiple source signals from a single observation vector of distributed array. Hankle matrixes are firstly constructed by using the single snapshot of every subarray element. Then low accuracy and unambiguous DOA estimations are obtained by the single subarray, while high accuracy and ambiguous DOA estimations are obtained by the distributed array. Finally, high accuracy and unambiguous DOA estimations are obtained by using automatic pairing decorrelating. This algorithm has no relations with the correlation signals and can fully take advantage of the large aperture to acquire high DOA estimation. Computer simulation results confirm the effectiveness of the proposed algorithm.
