2-D MIMO Radar: A Method for Array Performance Assessment and Design of a Planar Antenna Array

Abstract: In this article, a method for the assessment of the performance and for the design of a 2-D-array for multiple input multiple output (2-D-MIMO) radar applications is presented. The proposed approach is based on the analysis of the ambiguity function associated with the array. Such analysis leads to the definition of an area in the 2-D-angular field-of-view of the radar, denoted as ambiguity-free region, characterized by a low probability to obtain ambiguities in direction of arrival estimation. Simulations of … Show more

“…With the receivers located close to the MMICs, an interleaved sparse array with a hardware aperture size of 184 × 40.5 mm 2 is designed. Utilizing the genetic optimization from [6], the Rx antenna positions are optimized to adhere the design restrictions and to form an unambiguous array. The optimized Rx array performance is analyzed and shown in Fig.…”

“…In engineering applications, two-dimensional (2D) direction estimation, i.e., 2D-DOD and 2D-DOA estimation, is more attractive than the former. It is well-known that in order to obtain 2D angle estimation using the scalar-array-based MIMO radar, non-linear Tx arrays and Rx arrays must be adopted [20][21][22][23], e.g., rectangular array, circular array, arbitrary array. Unfortunately, these nonlinear scalar geometries are usually too complex to be conformal with the platform.…”

“…Conventional MIMO array setups using non-uniform spacing do not have a straightforward design rule, so the setup is often determined using a genetic algorithm with different possible optimization goals: low sidelobe levels [4], channel capacity for communication systems [5], minimum beamwidth/maximum aperture [6], or a maximum angular range for unambiguous angle estimation in the azimuth angular range [7] or in 2-D [8].…”
