Abstract
- 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 numerical tests and simulations. Experimental results have demonstrated significant resolution improvements for forward-looking imaging in coherent scanning radars. [ABSTRACT FROM AUTHOR]
