Calibration system and technique for a scalable, analog monopulse network
First Claim
Patent Images
1. A calibration process for an analog monopulse network in a phased array having a sub-array of antenna elements, the process comprising:
- calibrating a receive sum channel using a near-field data collection technique to generate receive sum channel calibration values; and
after generating receive sum channel calibration values, calibrating at least one receive delta channel using a far-field data collection technique wherein the generated receive sum channel calibration values are used in the calibrating of each of the at least one receive delta channels.
