The influence of the attitude errors on the imaging quality was analyzed theoretically.
The mean attitude errors for the collected 53 sequences of the IMU data are shown in Fig. 10.
A point-by-point error-compensation method for solving the azimuthal-direction space-dependent attitude errors was also proposed.
Furthermore, a fast and highly accurate misalignment angle estimation method based on heading-rotation is proposed to estimate the level attitude errors and misalignment angles simultaneously.
