Abstract :
The invention of the synthetic aperture radar (SAR) principle dates back to the early 1950s. The basic idea is to filter targets in a side looking radar according to their Doppler history in azimuth and by pulse or FM modulation compression in range. Since this time SAR systems have been, from a technical point of view, considerably refined to the state of the art where resolution and accuracy are close to the theoretical limits. This paper presents a new system idea for a single frequency SAR, where resolution is achieved by phase comparison. The system configuration becomes extremely simple and is suited for groundbased and airborne high resolution SAR
