Abstract

The number of optical true time delay (OTTD) is too many while operating in wideband and wide-angle condition for optically phased array radar. To solve the problem, a beam-forming method for optically phased array radar with sparse array is proposed. Firstly, the influence factor for main-lobe deviation is discussed. Secondly, a configuration of sparse antenna array is presented and then, on the basis of this, a beam-forming method based on Compressed Sensing theory is put forward. With this method, just a small amount of OTTD is required for wideband and wide-angle scanning. Finally, the effectiveness of this algorithm is validated by the simulative results.
