PURPOSE:To make it possible to process a chaff difusion state generation means with one storage face without transferring an image by performing the processing by a digital technique in a control circuit while scanning an area on a main storage device which is determined by the start address and the end address. CONSTITUTION:Main storage device 1 has corresponding storage elements so that the whole of the radar display part can be covered, and auxiliary memory 2 stores the start address, which indicates the diffusion start point of chaff at every fixed time, and the end address which indicates the diffusion end point. Then, the processing is performed by a digital technique in control circuit 4 while scanning the area on the main storage device which is determined by the start address and the end address, and information obtained by simulating the diffusion state of chaff is stored in main storage device 1, and contents of main storage device 1 are read out by the polar coordinate scan system synchronized with the radar display part, thus displaying the diffusion state of chaff on the radar surface simulatively. |
