Web由于经典卡尔曼滤波无法适用于非线性状态空间模型,所以需要采用非线性滤波算法处理AoA观测方程。扩展卡尔曼滤波(extended Kalman filter, EKF)通过一阶泰勒级数近似得到线性化的观测方程,但是截断误差使得EKF在初始状态误差和观测噪声较大时容易发散[10]。 Webknown as the Cram´er-Rao Lower Bound (CRLB) for the variance of an unbiased estimator of φ(θ.) (3) An estimator whose variance is equal to the CRLB is called a most eﬃcient estimator The eﬃciency eff(φˆ) of an unbiased estimator φˆ of φ(θ) is deﬁned to be the ratio eff(φˆ) = CRLB Var(φˆ) Note that 0 ≤ eff(φˆ) ≤ 1 for ... ginseng tea and diabetes

WebAug 26, 2024 · Terrain-referenced navigation (TRN) is a technology that estimates the position of an aircraft by comparing the terrain elevation on a digital elevation model (DEM) and the altitude measured by an altimeter. The particle filter (PF)-based TRN has been widely used for unmanned aerial vehicles (UAVs) operating at a high altitude.
