Aiming at the deficiency of algorithm of the radar simulator echo images generation, a modified algorithm was proposed, in which the geographical coordinates of the shoreline was transformed into plane coordinates by Vincenty’s formula, as result effectively solved the image deformation problems by using the Mercator projection coordinates to generate radar image and made the orientation and distance calculation more accurate. The modified RDP (Ramer-Douglas-Peucker) algorithm was used to simplify the shoreline data, which improved the rendering efficiency of radar images. The Rayleigh, Weibull and uniform distribution model were used to modelling and simulation of radar clutter. By a method of the clutter image generation and display based on computer image cropping, a better clutter and circumferential scanning was achieved. On the basis of the above algorithm, the JRC-JMA-9100 series radar simulator with better simulation results is developed.
