High-compacted FM-CW SAR for boarding on small UAVs

Autor: Albert Aguasca, R. Acevo-Herrera, Xavier Fabregas, Jordi J. Mallorqui

Publikováno v: IGARSS (2)

In this paper a compact, lightweight, low power consumption airborne SAR sensor able to be fitted in an UAV is presented. The Air-Based Remote Sensing (ARBRES) system is based on the previous experience acquired in developing GB-SAR sensors [7–8] f

On the use of compact L-band Dicke radiometer (ARIEL) and UAV for soil moisture and salinity map retrieval: 2008/2009 field experiments

Autor: Albert Aguasca, Adriano Camps, Xavier Bosch-Lluis, R. Acevo-Herrera

Publikováno v: IGARSS (4)

A light-weight L-band radiometer has been designed and implemented at the RS Lab of the Universitat Politecnica de Catalunya (UPC) to gather radiometnc airborne data sets. The design of the compact L-band Dicke radiometer (ARIEL) and a general overvi

Determining the intermodulation intercept points by spice of weakly nonlinear circuits connected in CAS-cade

Autor: Linares-Miranda, R. Acevo-Herrera, H. Jardon-Aguilar

Publikováno v: IEEE 6th International Symposium on Electromagnetic Compatibility and Electromagnetic Ecology, 2005..

The intermodulation intercept points of weakly nonlinear circuits are studied. The output second and third order intercept points are obtained with SPICE intermodulation components. Cascade stages of nonlinear circuits are analyzed and the effect of

Intermodulation interception points of nonlinear circuits connected in cascade

Autor: H. Jardon Aguilar, G. Monserrat Galvan Tejada, R. Acevo Herrera

Publikováno v: (ICEEE). 1st International Conference on Electrical and Electronics Engineering, 2004..

The influence of the input and output matching conditions on the third order intermodulation intercept points (IP3) of two amplifiers connected in cascade is investigated. Here we show that in order to get high convergence between prediction of the I
