The problem of 2-D angle estimation for coprime multiple-input multiple-output (MIMO) radar is considered. and a low-complexity propagator based method is proposed. Coprime MIMO radar is configured with transmit and receive rectangular arrays. where transmit array has N×Q elements while receive array has M×P elements (M is coprime to N while P is coprime to Q). https://unitedssports.shop/product-category/volleyball-balls-beach/
