<p>PURPOSE: To obtain a radar image processor by which three-dimensionaly shape information on a target is obtained by a method wherein an image-call selection means which selects an image-cell in every region is used, an image-cell acceleration computation means which computes the second derivative of the phase with respect to the time and converts the result to the acceleration so as to be output and a three-dimensional-radar-image creation means which combines three-dimensional amounts and the intensity of an image-cell tracking point so as to output them as the three-dimensional radar image of the tracking point. CONSTITUTION: An image-cell tracking device 13 extracts the image cell of every target part on the basis of a position on a range Doppler plane from an image-cell selection device 12 and on the basis of the set of complex number values, it tracks a movement stretching over image cells of every target part, and it selects the image cell to be used as an object so as to be output to an image-cell acceleration computation device 14 and a three-dimensional radar-image creation device 15. The device 14 computes the phase of the complex number values at every selected image cell from the device 13, it computes a second-order defferential with reference to the time of the phase at every selected image cell, and it converts a computation result into an acceleration so as to be output to a device 15. The device 15 outputs a three-dimensional radar image to a three-dimensional radar image display device 16.</p> |
