Abstract : This program has developed a hardware compressive fiber optic (FO) true time delay (TTD) system for broadband UHF and L band high performance Phased Array Antenna (PAA) applications. The TTD steering is based on a unique architecture that employs both electronic and FO programmable delay lines in conjunction with optical wavelength division multiplexing (WDM) to dramatically reduce system complexity, hardware, weight, volume, and cost. This report describes the development of the prototype transmit and receive WDM TTD systems and the results obtained from the antenna range demonstrations.
