The accuracies of several estimates compared with the actual errors assumed are listed in Figure 7-10. Figure 7-10. Phase Estimation Example This rather simple example has demonstrated the feasibility of inferring simple surface distortion and phase errors from amplitude measurements within the main beam. Sensors far from the main beam could be used to sense the level of random phase errors. A loss of rectified power with little change in beamwidth would imply tube or subarray outages.
