A bi-channel electrooptical scanning
laser imaging
radar transmitting
system for down-looking synthetic aperture comprises a
laser, a
half wave plate, an aperture diaphragm, a first
polarization beam splitter, a first electrooptical
scanner, a first cylindrical mirror, a second
polarization beam splitter, a first 1 / 4 wave plate, a first reflection mirror, a third
polarization beam splitter, a second 1 / 4 wave plate, a second reflection mirror, a second electrooptical
scanner, a second cylindrical mirror, a fourth polarization
beam splitter, a
transmitter-
telescope primary mirror, a high-
voltage power source and a
signal generator. The bi-channel electrooptical scanning
laser imaging
radar transmitting
system is capable of electro-optically scanning two channels of light beams and ultimately realizing parabolic
equipotential line difference of two polarization orthogonal light beams at a far-field target, is used for scanning targets, simple in structure, free of mechanical scanning, small in size, light in weight, and particularly suitable for onboard or
satellite-borne high-speed operating carrying platforms, and response speed for electrooptical
phase modulation wave surfaces is fast and up to
nanosecond level.
