Low-cost, panelized digital array radar antennas

The design challenges associated with the development of the antenna array for a highly-integrated, low-cost, panelized radar system have been presented, and the methodology for the development of a digital array radar (DAR) antenna panel has been detailed. Now that a solution for the maximization of scan range in in the DAR antenna panel has been identified, the next step is to integrate real T/R modules into the antenna panel and interface it with a fully-digital backend to ultimately demonstrate the flexibility and capability of this new, low-cost radar system.
