  7. Abstract:
  8. Today, the use of radar technology and its various applications in different areas of science is no secret. The developed countries are looking to increase their ability to use new radar tools. Synthetic aperture radar is one of the most modern and efficient equipment imaging of the surface. One of the major advantages of synthetic aperture radar is imaging capabilities at night and bad weather conditions if the imaging methods used in the camera have limitations in night and bad weather conditions. There are different methods for extracting the images, one of the most important algorithms is Range Doppler Algorithm which is used to obtaining images from raw data received. Because of the huge amount of processing, this algorithm implemented in non-real time. In this study the Range Doppler Algorithm implemented in real-time which have high and optimized processing speed using optimized maps to provide SDRAM memories with respect to implementation techniques and using different blocks in the form of pipe line. With respect to the type of implementation of different blocks such as azimuth FFT and RCMC the using of hardware reduces greatly and it enable the implementation in existence hardware
