Efficient true-time-delay adaptive array processing We present a novel and efficient approach to true-time-delay (TTD) beamforming for large adaptive phased arrays with N elements, for application in radar, ... S Kraut,AW Sarto - Proceedings of SPIE - The International Society for Optical Engi...
We demonstrate a true time-delay fiber-optically controlled phased-array transmitter with eight broadband spiral elements in a sparsely-populated array. The transmitter bandwidth is microwave-component limited to 2-18 GHz frequency range. The transmitter shows ±50° azimuth steering with no observed ...
The time delay was measured for a wavelength tuning range from 1537 to 1547 nm in 10-nm steps. The far-field radiation patterns of the antenna system were measured at 9 and 10.3 GHz, and they showed no beam squint. The true-time-delay formation idea presented here is suitable for not ...
