Description

Active electronically scanned antennas (AESA) for radar have the potential to be low-cost provided the array architecture is designed for production using commercially available manufacturing processes. Most modern radar antennas employ some form of nulling to reduce sidelobes in key steering directions. For a transmit AESA the most cost effective implementation is to use phase only to steer the main lobe as well as dynamically move the position of sidelobe nulls. Doing phase-only nulling in real time for a large AESA requires specialized optimization techniques to rapidly converge on a suitable transmit phase function. This project addresses optimization of array phase functions suitable for a low-cost, scalable active transmit antenna.
