Abstract :
Phase shift in angle tracking system leads to a decline of tracking precision. In terms of mono-pulse angle tracking system based on amplitude comparison of sum signal and difference signal with digital phase comparison technology, the paper analyzes the system phase shift and discusses the effect of it on angle tracking. Then, two methods to compensate phase shift are introduced with their efficiency verified by experimental data.
