State-of-the-art and Trends in Phased Array Radar
نویسنده
چکیده
The paper first introduces phased array configurations for radar and astronomy applications. In radar various trends can be observed, on the one hand driven by cost issues and on the other hand by increasing performance demands. The trends discussed, are the increasing bandwidth, the improvement of the Power Added Efficiency of transmit/receive modules, the phase shifter technology, alternative radiator designs, substitution of analog technology by digital technology and the introduction of sparse arrays. The paper concludes by observing that in radar applications phased arrays are now commercially viable, but that due to their complexity the cost will maintain to be high.
