Of active phased array radar method for correcting a multi-channel

The present invention discloses a method of active phased array radar multichannel correction, comprising a plurality of receiving channels arranged in the active phased array radar system, each receiving channel comprises a subset of a plurality of frequency domain carrier; for the gain magnitude plurality of signals received same channel subset of carriers, and the gain amplitude of the same subset of carriers of different receiving channel is corrected. The present invention is effectively compensate for inconsistencies receiving channel amplitude characteristic, a better multi-channel correction performance.
