| Abstract: | The domestic and international research actuality of the optical delay phased - array radar（ antenna）is analyzed, and the research institution and the latest research progress is analyzed also. The sort of phase- array rader （antenna）, key technology and representative diagram is refined. Phase-array rader （antenna）is classified as the common and dispersion fiber delay lines／ the optical delay of wavelength- division multiplexing combined with muti- wavelength laser／ the optical delay of free space segment combined with LCD switch ／ the optical delay of Prague,chirped fibre gating ／ the optical delay of plane wave- guide technology ／ the optical delay of sound - optical technology. Domestic and international research general picture of the optical delay of phase - array radar （antenna） is discussed. |
