Abstract:
In this paper, a photonic true time-delay technique for phased-array beam steering is proposed and analyzed for radar systems. It uses a High-Dispersion Compensation Fiber (HDCF) and a phased array antenna, which can provide a continuous radio-frequency squint-free beam scanning. When the dispersion of the fabricated HDCF is as high as -1020±31 ps/nm/km, the laser wavelength can be tuned from 1549.95 to 1550.2 nm. The experimental results confirmed that the scanning angle of far field radiation patterns for the proposed technique can be tuned from -220 to +290 at frequencies 5.9, 12.7 and 17 GHz.
