Abstract
A method for display of radar data includes performing a first radar scan to obtain, for at least one object (24), a first range reading, a first azimuth reading, and a first altitude reading. A second radar scan is then performed to obtain, for the at least one object (24), a second range reading, a second azimuth reading, and a second altitude reading. Position and travel direction of the at least one object (24) are computed within a predetermined cylindrical volume (20), according to readings from the first and second radar scans. An icon (34) is assigned to the at least one object (24). A reference point (R) is determined for the predetermined cylindrical volume. The icon (34) is then displayed within the predetermined cylindrical volume (20) in stereoscopic form.

9. A method for display of radar data comprising:
-
(a) forming a first raster scan image from a first radar unit by obtaining, for each elevation angle in a first sequence of elevation angle values, and for each azimuth angle in a first sequence of azimuth angle values;
at least one reading at a first distance;
(b) forming a second raster scan image from a second radar unit that is spaced apart from the first radar unit by obtaining, for each elevation angle in a second sequence of elevation angle values, and for each azimuth angle in a second sequence of azimuth angle values;
at least one reading at a second distance; and
(c) displaying the first and second raster scan images as a stereoscopic pair of images. - View Dependent Claims (10, 11)
