The apparatus uses individual phase registers for signal received from each antenna to solve the phase difference concurrently. The invention also discloses an attitude sensing method where only one receiving antenna is required. A method and structure for using variable correlation width is also disclosed to optimize noise cancellation under different noise environment.Field of SearchAttitude determination | |
