PURPOSE:To reduce the data processing time, by adding a processor for vector computation and a memory for memorizing data to be processed therewith to the output of a host computer. CONSTITUTION:A magnetic tape on which an input raw image data is recorded is applied to a magnetic tape reproducer 4 and once an output is produced to a magnetic disc unit 5, the raw image data is stored into a memory 3 through a host computer 1 and a processor 2. Under such a condition, the signal processing for a synthetic aperture radar is donne with the processor 2. Having all data for processing, the memory 3 allows the random accessing and data accessing can be done at the same time both in the range-wise and azimuth-wise processing by an address control. Thus, in addition to no need for corner turn processing, all image data are memorized into the memory 3 to enable a high- speed processing by continuously supplying data to processor 2 on a pipeline system. |
