Abstract

Amplitude comparison angle measurement is a practical technology for its simple structure and low complexity. MIMO radar can view a broad angular sector and form multiple simultaneous joint-beams. It is very suitable to implement multi- beam amplitude comparison angle measurement in MIMO radar. As the accuracy of angle measurement depends directly on the half-power beamwidth of the antenna pattern, we make detailed analysis on the joint-beam properties for MIMO radar, and derive the mathematical expressions of the half-power beamwidth and peak sidelobe level. We also provide an effective method for allocating the multibeam directions in this paper.
