Stereo display for position sensing systems

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.

A method for display of radar data about an object comprising:

• obtaining first coordinates of the object at a first position at a first time;
• obtaining second coordinates of the object at a second position at a second time later than the first time;
• computing the direction and position of the object according to the first and second coordinates;
• and
• displaying an icon to represent the direction and position of the object.
