[Abstract]:In this paper, a multi-beam receiving network of optically controlled phased array radar based on fiber dispersion true delay technique is proposed. The principle of this network is that according to the dispersion characteristics of optical fiber, it is mainly composed of dense wavelength division demultiplexer (DWDM) and optical fiber delay module. DWDM realizes multi-channel optical synthesis. The optical fiber delay module composed of multiple optical switches and optical fiber delay rings realizes the delay adjustment of the synthesized multi-channel optical carrier, so as to realize the beam scanning. According to the principle scheme, a set of 16-channel optical receiving and double beamforming network is developed to realize 16 different beam pointing scanning from-40 擄to 45 擄, and the switching speed is less than 30 渭 s. The darkroom test proves its beamforming ability.
