Abstract :
A convenient method for measuring synthetic-aperture radar (SAR) azimuth antenna patterns and microwave penetration of soil or trees using spectrum analyzers and amateur-radio antennas is described. The received power of a ground receiver is estimated for several SARs. This estimation suggests that spectrum analyzers can be used for ground measurement during SAR observation. Results of in situ experimental measurements which were made during the NASA/JPL DC-8 SAR campaign in summer 1990 in the JAROS/NASA JERS-1 simulation project are presented. A discussion and perspectives on applications for JERS-1 SAR are included
