Angular Superresol for Signal Model in Coherent Scanning Radars.
IEEE Transactions on Aerospace and Electronic Systems（2019）
摘要
Noncoherent signal models are widely applied to angular superresolution in forward-looking imaging radars. However, the relative phase influences the resolvability of the model in coherent applications. We reveal the reason why phase shifts affect deconvolution and propose a coherent signal model by replacing the antenna power pattern with the radiation pattern. REGU, TSVD, and IAA are utilized in...
