【摘要】：文中提出了一種基于光纖色散真時延技術的光控相控陣雷達多波束接收網絡。該網絡制作原理是根據光纖的色散特性,主要由密集波分復用器(DWDM)和光纖延時模塊構成。DWDM實現對多通道光合成,多個光開關和光纖延時環(huán)組成的光纖延時模塊實現對合成的多路光載波進行延時量調節(jié),從而實現波束掃描。依據原理方案,研制了一套16通道光接收、雙波束形成網絡,實現從-40°到+45°的16個不同波束指向掃描,切換速度≤30μs。暗室測試證明了其波束形成能力。
[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.
