摘要
实延时是相控阵天线波束合成的一种重要手段,而随着带宽和阵列单元数目的增加,光学实延时技术的采用已成为一种重要趋势。介绍了受激光子回波的物理现象,分析了这一现象产生的原理,说明了光实延时的产生方法。
A true time delay(T/D) is a mean for beam-former of phased-array Antennas. With the increment of the array number and bandwidth, the adopt of optical true time delay( OTTD ) is become an important trend. The physical phenomena of stimulate photon echoes ( SPE ) are introduced. The principle is analyzed, and the method of how to produce OTTD is explained.
