Abstract :
A lightweight radar system, suitable for use on board small airborne platforms, has been built and tested. The radar system comprises a digital receive array, offering full beam forming flexibility at the cost of high data rates and heavy processing loads. In this paper, the requirements and architecture for multi-channel SAR processing are discussed and processing results from recent airborne campaigns are presented.
