Abstract

Radar systems, operating for SAR (Synthetic Aperture Radar) for ground observation or for surveillance, need very high resolution. The achievement of very high resolution in the range of 15 cm or less, that enables stationary targets analysis, requires wide instantaneous bandwidth, accurate and programmable waveforms. On the other hand, low velocity moving targets to be discriminated from stationary ones are demanding in low spurious and low phase noise. This paper presents a low noise and flexible digital frequency synthesizer for wide band application suitable for very high-resolution Radar.
