Abstract
A polarimetric C-band airborne SAR has been developed in the Netherlands. The system makes use of a phased array antenna with solid state amplifiers. The project consists of two phases, a definition phase and a realization phase. The definition phase consisted of the actual realization of a SAR research system, which made its first successful test flight in November 1990. The research system is based on the concept of a wide beamwidth antenna, rigidly fixed to the aircraft. Pulse compression and a high PRF ensure sufficient sensitivity in this system, which is equipped with a 160 Watt peak pulse power solid state transmitter. The processing is done off-line. In the current realization phase the polarimetric system is under its first airborne tests. Its design is based on the experience gained with the research system. The system makes use of a phased array with dual polarized patch radiators and will be equipped with solid state amplifiers. The technology used and the expected system performance are representative for future spaceborne systems. This paper gives an overview of the SAR research system and the results obtained with this system. The polarimetric system design and use are discussed. Apart from the use as an advanced polarimetric airborne SAR, their is the perspective of using this system as a demonstrator for ESA's future ASAR system.
