Abstract:According to the characteristic of the echo of highfrequency ground wave radar(HF GWR), which is one-dimensional narrow band signal, a virtual direction of arrival(DOA) matrix is constructed at first, then the DOA of target evaluation is achieved by the method of resolving equations for two-dimensional DOA matrix. And this method bases on the redundancy information of a linear two-row array of antennae. Both the simulation process and the treatment results of measured data (in the case of low SNR echoes and sh… Show more
