Abstract

A high resolution synthetic aperture radar (SAR) experimental system called phased array multi-functional imaging radar (PAMIR) is currently under development at FGAN-FHR. This system uses a very high bandwidth and performs a coherent integration along a large synthetic aperture to achieve a very high resolution in the order of one decimeter. PAMIR covers a large angular sector and operates in sophisticated modes using multi-channel signal processing. This variety of tasks can be fulfilled only by use of a wideband phased array antenna. The need for a large bandwidth rises a lot of specific problems which have to be solved in conjunction with it. Now the phased array antenna and the system has come to a first stage allowing gathering radar data using a 24 column element array.
