ANTENNA SIGNAL PROCESSING APPARATUS
First Claim
Patent Images
1. A method of compensating for a vibration induced error in a signal emitted or received by an antenna, the method comprising the steps of:
- measuring the vibration of said antenna estimating the error induced by the vibration and correcting the signal transmitted or received by the antenna as a function of the estimated error.

Abstract
An antenna comprises at least one accelerometer capable of monitoring mechanical vibration. Associated signal processing means provides a transfer function which is used to convert signals received from the accelerometer into an error estimate, which can then be subtracted from signals received from the antenna.
