Embodiment
[0048] Taking the commonly used warning radar as an example, the technical solution of the present invention is described in detail, but the protection scope of the present invention is not limited to the embodiments.
[0049] Suppose the specific content is as follows:
[0050]
[0051] (1) Setting parameter values, the radar power range R=200km, the side length W=2000 of the index image I, and the number of area types N=2.
[0052] (2) create an index image I, the size is 2000 * 2000, the distance represented by each pixel is 2R / W=2 * 200 / 2000=0.2km; create a data area, the data size of the area data area D is selected as N A =1, that is, one byte is used, the size of the data area of the entire area is 2000×2000×1, and the statistical data area D T The data size is selected as N T =1, the size of the entire statistical data area is 2000×2000×1, initialize the data area and set all to 0.
[0053] (3) According to the setting parameters, the position conversion formul...
