Beam pointing error analysis for phased array antennas with true time delay modules

The beam pointing error theory for the phased array antennas (PAA) with true-time-delay (TTD) module is proposed in closed form and is confirmed to be valid. The proposed theory easily gives the optimum subarray size, which is a unit of a TTD module, and maximum delay length of the TTD module in ord...

Zusammenfassung:The beam pointing error theory for the phased array antennas (PAA) with true-time-delay (TTD) module is proposed in closed form and is confirmed to be valid. The proposed theory easily gives the optimum subarray size, which is a unit of a TTD module, and maximum delay length of the TTD module in order to attain the desired beam pointing accuracy.
