AICBM Decoy resolution by coherent integration

摘要

A receiver in a radar system has two feed horns which supply a hybrid. The hybrid sums the amplitude of the signals from the feed horns at its first output and subtracts the signals at its second output. The outputs are each converted to I.F. by mixers, de-chirped, and then are coherently integrated. The integrated output of the difference is fed to a servo for tracking. The integrated output of the sum is fed through a control unit to control the beat signal of the mixers.
