A novel microwave staring imaging method based on short-time integral stochastic radiation fields

Abstract

For microwave staring correlated imaging method, high-precision requirement of time synchronization between stochastic radiation fields and scattered echo signals must be satisfied. In order to reduce its influence on microwave correlated imaging results, a novel microwave staring correlated imaging scheme is proposed based on short-time integral stochastic radiation fields. Then the short-time integral correlated imaging model on the intra-pulse stochastic radiation fields and intra-pulse scattered echoes is established, which improve its tolerance capability of time synchronization error of the imaging system, meanwhile, the temporal-spatial stochastic characteristics of short-time integral radiation field can be maintained as well as its super-resolution potential of microwave correlated imaging. Finally, the effectiveness of this imaging method is validated by the numerical simulations.
