“…The bistatic sonar system is composed of a transmitted station used to send out the acoustic wave and a received station used to receive the reflected acoustic wave. With regard to the traditional stationary bistatic sonar system [11][12][13], it is difficult to achieve precise target localization due to the lack of adequate measurement information. In order to make up for this shortage, we adopt the mobile bistatic sonar system [31] shown in Figure 1 to achieve the necessary measurements in this study.…”

“…In the bistatic sonar system, the different types of common measurements containing the bistatic range (BR) [11][12][13] and the angle of arrival (AoA) [14][15][16] are used to estimate the target location. In [17], an AoA-based localization method whose calculation is simple but sensitive to the measurement error is applied to the bistatic sonar system for target localization.…”

“…Currently, the performance of the BR-based localization algorithm is closely related to the propagation delay from the transmitted station to the target to the received station. Therefore, in order to ensure the accuracy of delay measurement, the transmitted station and the received station must be synchronized precisely [11][12][13]18]. However, the constrained underwater environment makes the task of precise time synchronization between the transmitted station and the received station difficult to achieve, which will degrade the localization performance in the presence of the synchronization error.…”

Active localization of a stationary target is one key issue in applications of bistatic sonar based on bistatic range (BR) measurement. However, the complex underwater environment makes achieving the synchronization between the transmitted station and the received station difficult. For solving the synchronization problem, this study relies on mobile bistatic sonar to acquire measurement information at multiple time steps. After that, the target location and clock bias are jointly estimated by solving a non-linear least square problem. To this end, a recursive scheme is proposed to optimise the measurement cost and reduce the impact of the initial value to achieve accurate estimation by taking full advantage of the redundant measurement information. Orthogonal transformation is used to ensure computational efficiency and numerical reliability. The Cramer-Rao Lower Bound (CRLB) is also derived as a lower bound on the error in estimating the target position and clock bias. Simulation results show that the proposed method achieves the CRLB performance and optimises the measurement cost over the small error region under Gaussian noise.

<div class="section abstract"><div class="htmlview paragraph">To satisfy the power and energy requirement of the systems, such as electrical vehicles, the battery packs are constructed with hundreds of single cells connected in series and parallel connection. The most significant difference between a single cell and a battery pack is cell-to-cell variation. Not only does cell-to-cell variation have a big effect on the available energy and power of the battery packs, but also it causes early degradation of battery and potential safety issues. The cell variation effects on battery packs are widely studied because it is of great significance for battery sorting and management scheme. In this paper, battery pack inconsistency is clearly defined and the resulting battery capacity loss and aging acceleration problems are analyzed in detail. A comprehensive LiFePO<sub>4</sub> battery pack model was established, which has taken into account cell-to-cell variation, thermal model, capacity degradation, resistance increasing and different battery topologies. A set of parameters are introduced to study the cell variation and their impacts on battery pack are analyzed through the different working conditions simulation. The battery sorting suggestions are given based on the quantitative result from the simulation. The quantitative results from this research demonstrate that the capacity, self-discharge rate and initial <i>SOC</i> in series battery group, capacity, resistance in parallel connection are the major affecting parameters of cell-to-cell variation, which leads to significant aging acceleration and capacity loss of the battery pack. In the meanwhile, it has been pointed that dynamic load profile caused faster cycling aging and more serious self-balancing compared with the constant load profile.</div></div>
