Title: Multi-frequency Co-prime Arrays for DOA Estimation


Co-prime arrays have found broad applications in both areas of radar and sonar. Co-prime arrays are two subarrays with co-prime elements and co-prime inter-element spacing. The equivalent co-array includes a large number of virtual elements, thus increasing the number of degrees of freedom and enabling direction of arrival estimations of a number of sources much higher than the number of physical elements. In this talk, we discuss techniques based on dual and multiple frequencies which allow the co-prime receiver array to handle a higher number of sources in the field of view compared to its single-frequency counterpart. In particular, we employ dual and multiple frequencies to fill holes in a co-array array, creating a much longer aperture with consecutive elements, thereby enhancing DOA estimation performance. We also present ways to use dual co-prime frequencies to create virtual co-prime array from a linear uniform array. Several simulation examples are provided for both cases.
