| Abstract: | Coherent optical beam formation is a new wideband radio frequency beam-forming technology,which is based on optical interference,diffraction principle and optical Fourier transformation.The principles of this technique are introduced and a physical model is proposed.The results of theory deduction and simulation show that coherent optical beam-former can construct multi-beam and have some merits in small bulk,narrow beam width,large space covering and counteracting electromagnetism interference. |
