摘要：

Microwave carrier generation along with the signal processing required for dynamic beamsteering of a high resolution phased array antenna with an arbitrary radiation pattern is accomplished using optical components. It is shown that a deformable mirror type spatial light modulator can establish a truly arbitrary continuous optical phasefront which is directly converted to spatial RF phase information by means of an optical heterodyne system. Experimental results which simulate the performance of the actual system are presented. A spatially integrated optical implementation is presented which provides mechanical stability and essentially eliminates the drift problems usually encountered in free space systems. © 1990 IEEE
