A. State Augmentation

\

\

\ B. System Model

\ We now define the mathematical model of the gyroscope and radar sensors a

\

\

\

\

\

\ The augmented transition matrix is then given by

\

\ As a result, the error covariance of the augmented system is propagated as [28]

\

\ C. Measurement Model

\ Model The DeRO system leverages measurement from both radar (distance of the targets) and tilt angles calculated from accelerometers. We shall describe each measurement model in detail

\

\ D cases. Unlike in [29], where each target’s distance measurement is directly used, we employ the entire scan for matching to determine the distance between frames. This strategy leads to a significant reduction in computation

\

\ According to the relationship between Euler angles and misalignment angles [21], we establish the following linearized measurement model to update the DR estimation

\

\ D. Implementation

\ on The detailed step-by-step practical implementation of the DeRO is outlined in Algorithm 1. In our approach, the procedure for each sensor is executed as soon as the corresponding sensor’s data becomes available.
