Abstract:
1. A radar comprising: a sensed image data generation means for extracting sensed image data corresponding to pixels of an image memory from received sensed data, and generating current written sensed image data to be written into the image memory, based on the extracted sensed image data and previously written sensed image data stored in the image memory; an image memory storing written sensed image data for one scan; a display device showing display image data based on the current written sensed image data; and a behavior data generation means comprising: wherein the sensed image data generation means recognizes characteristics of the sensed image data of the corresponding pixels from behavior data of a time series input from the behavior data generation means, and generates the written sensed image data that is written into each pixel through a filtering process and a selection process in accordance with the result of this recognition; and wherein the sensed image data generation means detects, from the behavior data, a presence ratio of the sensed image data and an instability ratio given by the number of times that the sensed image data changes within a predetermined period, and performs the filtering process and the selection process based on the presence ratio and the instability ratio.
