The hybrid MIMO phased array radar (HMPAR) is a notional concept for a multisensor radar architecture that combines elements of traditional phased-array radar with the emerging technology of multiple-input multiple output (MIMO) radar. A HMPAR comprises a large number, MP, of T/R elements, organized into M subarrays of P elements each. Within each subarray,(More)

The chloride content required for corrosion initiation of galvanized reinforcing bars is determined. The bars conform to ASTM A767, except that no chromate treatment was applied to allow the degree of hydrogen evolution for untreated bars to be evaluated. Test results, along with results for conventional (ASTM A615), low carbon chromium (ASTM A1035, MMFX),(More)

Multiple-input multiple-output (MIMO) radar is a multiple aperture technology characterized by the ability to transmit diverse signals at each aperture. This is in contrast to traditional phased-array radar whereby a single signal is transmitted with a phase shift applied at each element to enable steering of the transmit beam. The hybrid MIMO phased-array(More)
