This paper discribes a computer-controlled CCD image display system with high resolution

which has been develaped for checking the imaging effeciency and quality of the datum negative in the optical pracessor of a synthetic aperture radar.The hardware interface circuits for quickly transiering data and the design of assemlaly language programs are also introduced.With the specific high resolution colour graph-controlled circuit board the resolution of the system can be up to 1k1k8bits

hence it is very canvenient to adjust and test.The system is stable and relialale in properties and abundant in colaurs.The pseudo-colour real-time rolling display provides convenient conditions for digital image prosessing.
