@conference{10902/3115, year = {2010}, month = {9}, url = {http://hdl.handle.net/10902/3115}, abstract = {This paper presents the design of two ground based synthetic aperture radar (GB-SAR) systems working at 94 and 300 GHz respectively. Frequency-modulated continuous-wave (FM-CW) technique is used for both systems, being described in the first section. Afterwards the first design at 94GHz is presented, explaining its geometry of exploration and describing the architecture of the W-band radar setup. Regarding the integrated receiver system, two models of low noise (LNA) and medium power amplifiers are disclosed, presenting noise figure and S parameters curves comprising frequencies between 75 and 110 GHz (W-band). Finally the second radar setup working at 300GHz is presented, depicting the hardware block diagram and explaining the main performance parameters of the system.}, publisher = {URSI 2010, XXV Simposium Nacional de la Unión Científica Internacional de Radio, Bilbao}, title = {MMW FM-CW ground-based SAR}, author = {Abril, Jordi and Nova, Enrique and Broquetas Ibars, Antoni and Aguasca Solé, Alberto and Romeu Robert, Jordi and Jofre Roca, Lluís and Mencía Oliva, Beatriz and Grajal de la Fuente, Jesús and Pascual Gutiérrez, Juan Pablo and Fernández Ibáñez, Tomás and Tazón Puente, Antonio}, }
