<p>PURPOSE:To supply a display with images having less change in the shape of object image by preparing a new synthesized image from the image of object stored in an input image memory and the image of object stored already in a synthesized image memory. CONSTITUTION:A transmission trigger signal, antenna azimuth signal, and radar image signal are entered from a radar device, and a radar image input means 1 writes the image data turned into quanta for every azimuth and distance of radar into an input image memory 2 from time to time on real-time basis. At the same time, the output signal of this radar image input means 1 is pursued by an object pursuing means 31 in an identical object sensing means 3 and is compared with the the synthesized image till the time stored in a synthesized image memory 6 - for example, till (n-1)'th image if the input image at this time is assumed as n'th image to the antenna - and sensing of identical object image is conducted by a similarity judging means 32 and a calculating means 33. A moving amount sensing means 4 calculates the moving amount to current position of the synthesized image in a the synthesized image memory 6 which is sensed as the identical object image as described above. A synthesized image preparing means 5 then calculates the image of mean value of the identical object image in the synthesized image memory 6 and input image memory 2.</p> |
