Localization of Near-Field Sources Based on Linear Prediction and Oblique Projection Operator EI SCIE
期刊论文 | 2019 , 67 (2) , 415-430 | IEEE TRANSACTIONS ON SIGNAL PROCESSING
Abstract&Keyword Cite

Abstract :

This paper investigates the localization of multiple near-field narrowband sources with a symmetric uniform linear array, and a new linear prediction approach based on the truncated singular value decomposition (LPATS) is proposed by taking an advantage of the anti-diagonal elements of the noiseless array covariance matrix. However, when the number of array snapshots is not sufficiently large enough, the "saturation behavior" is usually encountered in most of the existing localization methods for the near-field sources, where the estimation errors of the estimated directions-of-arrival (DOAs) and ranges cannot decrease with the signal-to-noise ratio. In this paper, an oblique projection based alternating iterative scheme is presented to improve the accuracy of the estimated location parameters. Furthermore, the statistical analysis of the proposed LPATS is studied, and the asymptotic mean-square-error expressions of the estimation errors are derived for the DOAs and ranges. The effectiveness and the theoretical analysis of the proposed LPATS are verified through numerical examples, and the simulation results show that the LPATS provides good estimation performance for both the DOAs and ranges compared to some existing methods.

BeiDou Satellites Multi-GNSS Precise Orbit Determination with Ambiguity Fixed EI Scopus CSCD PKU

Abstract&Keyword Cite

Abstract :

Using the global distributed IGS and Multi-GNSS experiment(MGEX) data, a method of multi-GNSS integrated double-difference precise orbit determination(POD) of BeiDou navigation satellites is studied. Then a specific double-difference ambiguity fixing strategy for BDS is proposed. The orbit determination precision of using single system and multi-GNSS, as well as ambiguity-fixed solution and ambiguity-free solution, are compared based on real observation data. The results show that, compared with single system processing, the multi-GNSS integrated method can effectively improve the orbit precision of IGSO and MEO, but except for GEO. The result of IGSO and MEO ambiguity fixing by the proposed strategy is well. The ambiguity fixing success rate has been improved significantly, especially for long baselines. The ambiguity fixed success rateimproves form 40% to 60% or more on the whole. Ambiguity fixing shows a positive contribution to orbit accuracy of IGSO and MEO from the overlapping RMS with that of the free solution for comparison. The 3D-RMS of IGSO could reach 0.048 m, and that of MEO could reach 0.066 m. © 2018, Surveying and Mapping Press. All right reserved.

Abstract :

利用全球分布的IGS和MGEX站多模观测数据,研究了北斗卫星多系统融合双差动力学精密定轨方法,提出了适应北斗系统的双差模糊度固定策略.结合实测数据,对比了单系统与多系统融合、模糊度固定解与浮点解的定轨效果.结果表明:相比单系统定轨,多系统融合定轨能有效改进IGSO和MEO卫星轨道精度,但对于GEO卫星,多系统融合定轨并无优势;利用改进的模糊度固定策略对IGSO和MEO卫星双差模糊度进行固定,有效提高了长基线模糊度固定率,整体固定成功率由40% 提高到60% 以上;模糊度固定对定轨精度改进作用明显,IGSO和MEO卫星三维定轨精度分别提高了48% 和36%,达到0.048 m和0.066 m.

Subspace-Based Localization of Near-Field Signals in Unknown Nonuniform Noise EI CPCI-S Scopus

Abstract :

In this paper, we consider the problem of estimating the directions-of-arrival (DOAs) and ranges of multiple near-field narrowband signals impinging on a symmetric uniform linear array (ULA) in nonuniform noise in practical applications. By forming a Toeplitz-like correlation matrix from the anti-diagonal elements of the array covariance matrix to convert the nonuniform noise to a uniform one, a new subspace-based localization method is proposed, where the null space is obtained through eigendecomposition of the resultant Toeplitz-like matrix, and the MUSIC method is used to estimate the location parameters, while a new pairing scheme is presented as well. Additionally, an oblique projector based alternating iteration is presented to improve the estimation accuracy of the location parameters, where the "saturation behavior" encountered in most of localization methods is solved effectively. Furthermore, the Cramer-Rao lower bound (CRB) for the near-field signals in unknown nonuniform noise is also derived explicitly. Finally, the effectiveness of the proposed method is verified through numerical examples.
