<div>This paper proposes a new window-wise state of charge (SOC) estimation algorithm based on Kalman filters (KF). In the first stage, the equivalent circuit model's parameters are estimated by a least square estimation window-wise, assuming a linear SOC and open-circuit voltage (OCV) relation. The algorithm accurately estimates the parameters and observes the changes that depend on SOC. Moreover, based on the estimated parameters, the OCV values are identified. In the next stage, window-wise linear Kalman filter(ES-LKF) without hysteresis and extended Kalman filter (ES-EKF) and sigma-point Kalman filter (ES-SPKF) algorithm with hysteresis are executed to estimate SOC. Having fewer state equations and hysteresis parameters tuned up in an off-line way, the ES-EKF and ES-SPKF perform better than the algorithms considered in previous works. The algorithms are validated by experiments with real data obtained from lab tests.</div>

Рассмотрена задача сопровождения маневрирующего баллистического объекта на этапе входа в атмосферу с помощью пассивной антенной решетки. Предложено использовать многомодельный алгоритм на основе расширенного и сигма-точечного фильтров Калмана. Проанализировано влияние точности априорной информации на сходимость многомодельного алгоритма. С помощью математического моделирования проведено сравнение с одиночными фильтрами Калмана. The problem of reentry ballistic target tracking with a passive antenna array is considered. Multiple model algorithm based on extended and sigma-point Kalman filters is proposed. A priori information accuracy influence on the convergence of multiple model algorithm is analyzed. Using mathematical modeling, the results were compared with regular extended Kalman filters.
