ANTENNA CALIBRATION
First Claim
1. A method of continuous on-line monitoring of each element in an array antenna comprising the steps of:
- (i) transmitting known test signals to one or more elements of the array antenna;
(ii) monitoring responses of the elements to the test signals; and
(iii) comparing the response with expected responses for the elements to determine an operation condition of the elements.
