規則光學相控陣可以實現連續掃描，但是只適用於小角度的掃描，因為當掃描角度太大時要產生伴隨光束，平重影響掃描的質量，本文對其產生的原因進行了詳細的說明。 -
Due to restriction with the array aperture transition time, traditional phased array radar works under relative narrow signal bandwidth, so this restricts the application of phased array radar in the field where high performance is demanded. however, optically controlled phased array radar ( ocpar ) adopts the photoelectron technology, counteracts the aperture transition time via the method of optical true time delay ( ottd ), so it can realize wide instantaneous bandwidth and squint - free operation ; meanwhile, it can realize the miniaturization of phased array radar and has super anti - electromagnetism interference capability
而光控相控陣雷達採用光電子技術，通過光實時延遲的方法來抵消孔徑渡越時間，可以實現相控陣雷達的寬帶寬角掃描;同時也可以使得相控陣雷達小型化，並具有強的抗電磁干擾的能力;另外，由於光纖傳輸具有損耗低、頻帶寬等固有優點，採用光纖連接雷達天線和雷達控制中心，可以使兩者的距離較採用同軸電纜有較大的提高，更有利於保護雷達控制中心。 -
