当前,第25个太阳周期已进入强活跃时期,能引发大量电离层不规则体,进而对使得穿行其中的GNSS信号产生电离层闪烁。这已成为影响GNSS全球稳定导航定位服务的重要干扰源。对全球电离层闪烁进行广泛且全面的监测是消除闪烁对GNSS干扰的重要前提,然而传统电离层闪烁监测接收机(ISMR)分布有限,无法满足闪烁全球监测需求;测地型接收机分布广泛,但从其低采样数据中提取的闪烁因子缺乏新太阳周期长时序监测数据验证,导致其闪烁监测可靠性存疑。为此,本文基于近3.a新太阳周期测地型接收机数据,以ISMR提供的闪烁因子为参考,从代表性空间天气事件闪烁响应、日闪烁发生率、闪烁持续时间概率分布、闪烁日发生规律及其随极昼、极夜、地磁指数的特征变化等方面,对比研究了两种测地型接收机电离层闪烁因子(即电离层总电子含量变化率指数ROTI和沿弧段电子含量变化率指数AATR)监测北极高纬度区域电离层闪烁的准确性,并给出了ROTI和AATR在高纬度区域判断闪烁发生的经验阈值。结果表明,ROTI和AATR均能较为准确探测到地磁扰动、太阳活动等因素驱动的区域电离层闪烁,并能有效表征电离层闪烁统计学上的日变化规律,但两种闪烁因子不能准确区分闪烁和电离层电子密度梯度变化,导致在电子密度梯度变化剧烈期间存在较高虚警。该研究成果可为准确选择区域电离层闪烁监测因子提供指导。

The mobile loading arm(MLA) system is one of the most important mechanical equipments in the petrochemical industry consisting of rigid pipelines and rotating elbows. This paper researches the problems of dynamical modelling and tracking control. At first, an MLA dynamic model is built by using Euler-Lagrange function. And then, an adaptive third-order fixed time sliding mode(FDTSM) tracking controller with chattering free is represented, which enables the MLA system to dock with the vehicle tank mouth. In this paper, a new double-layer third-order fixed time sliding mode controller is first proposed to address the tracking problem in model-based MLA systems with known parameters. Moreover, considering the presence of modeling uncertainty and external disturbances,a nerual network adaptive FDTSM controller is designed to ensure that the close-loop system state tracking error converges to a bounded region around zero within a fixed time. Further, the stability of the close-loop system is proven by using the Lyapunov stability theorem. Simulation results illustrate the validaty of the controller.

Traditional equalization algorithms for multiple input multiple output (MIMO) systems suffer from high complexity and low convergence rate. So an improved adaptive reduced-rank joint detection algorithm of multistage Wiener filter (MSWF) based on rectangle blocking matrices is proposed. The MSWF is implemented by the correlation subtraction algorithm (CSA) structure and is called unitary multistage Wiener filter (UMSWF). The new scheme adopts rectangle submatrix as blocking matrix, which is chosen from the square blocking matrix for UMSWF. The proposed algorithm can reduce the size of the observation data vectors step by step in the forward recursion decomposition of UMSWF. Thus, the computational complexity is reduced and the convergence rate is increased. Theoretical analysis and simulation results show that this improved adaptive reduced-rank joint detection algorithm of UMSWF based on rectangle blocking matrix has better performance such as lower complexity and faster convergence rate. In particular, simulations are conducted in the verticalBell Labs layered space-time (V-BLAST) system which adopts BPSK modulation, where 4 and 8 antennas are equipped at the transmitter and receiver, respectively. Compared with traditional equalization algorithm based on UMSWF, our new method can achieve the same BER performance at high SNR with only 0.5 times that of computational complexity.
