An experimental real time one-bit (hardware) processor has been realized and is planned to operate in connection and during the Space Radar Topography Mission (SRTM). This is the first single pass interferometric Synthetic Aperture radar (SAR) in the space mounting on-board two radar receivers. During the mission, part of the XSAR raw data will be down-linked, re-coded at one bit and convolved (in time domain) with a one-bit coded filter function, to generate real-time images and associate interferometric fringes. The experiment is expected to be relevant to the emerging area of on-board real time processing (reduced weight and power consumption) and deep space microwave imaging (bandwidth saving). Results of the experiment are presented. The processor performance and (geometric and radiometric) image quality are discussed.
