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.
