Abstract

In this chapter, we explore a collocated overlapped multiple-input multiple-output (Overlapped-MIMO) radar waveform design, which is combined with an algorithm to share spectrum through null space projection (NSP) for the coexistence of radar and communications system. In this chapter, we extend the previous works [1, 2, 3], which consider a coexistence scenario where collocated MIMO radar operates in the same band as MIMO communications system, to a spectrum sharing topology of Overlapped-MIMO radar and MIMO communications system. The antenna array of collocated Overlapped-MIMO radar is separated into multiple subarrays for transmitting signals in this antenna orientation. The antenna elements are overlapped among the subarrays, where the elements of transmitting subarrays comprise coherent signals and inter-subarray signals are orthogonal to each other.
