Abstract
Described is a calibration technique for an Active Electronically Scanned Array (AESA) having a scalable, analog monopulse network.
Claims20
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;
- after generating receive sum channel calibration values, calibrating at least one receive delta channel 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.
A calibration process for a phased array having at least a sum channel and two difference channels, and comprised of a plurality of subarrays, the calibration process comprising:
- calibrating a receive sum channel using a near-field calibration technique to generate a set of sum channel calibration values;
- uploading the sum channel calibration values to the array;
- calibrating one or more receive delta channels using a far-field calibration process.
