Embodiment Construction
[0029] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.
[0030] In this embodiment, the radar detection area is obtained through the input radar parameter information and the aircraft penetration height; figure 1 As shown, a fast calculation method for radar terrain shadowing blind area at multiple heights includes the following steps:
[0031] (1) Set the parameter information of the radar, input the longitude and latitude of the radar coordinate position, the height value of the radar, the scanning range of the radar and the point density when calculating the maximum detection range on the altitude layer, and the multiple penetration flight heights that need to be calculated put in order.
[0032] (2) Obtain elevation information according to digital elevation model data, and calculate the maximum detection range of th...
