Thats a unique idea.You should consider the following idea to enhance your idea so that it would impact uniquely: SUMMARY Much attention has recently been paid to direction of arrival (DOA) estimation using compressed sensing (CS) techniques, which are sparse signal reconstruction methods. In our previous study,  developed a method for estimating the DOAs of multi-band signals that uses CS processing and that is based on the assumption that incident signals have the same complex amplitudes in all the bands. That method has a higher probability of correct estimation than a single-band DOA estimation method using CS. ,  propose novel DOA estimation methods for multi-band signals with frequency characteristics using the Khatri-Rao product. First,  formulate a method that can estimate DOAs of multiband signals whose phases alone have frequency dependence. Second,  extend the scheme in such a way that  can estimate DOAs of multi-band signals whose amplitudes and phases both depend on frequency. Finally,  evaluate the performance of the proposed methods through computer simulations and reveal the improvement in estimation performance.
