A radar volume in a cued direction is searched with sequential pencil beams. The cued direction is subject to uncertainty in the form of covariance. The covariance defines an ellipse rotated relative to the azimuth axis. Before determining the extent of the acquisition face, the ellipse is projected onto a viewplane normal to the radar range axis, and rotated so the principal axes are parallel with the traverse and elevation directions. The acquisition face is then found. The number of beams required to scan the search volume is determined. In one embodi...
1. A method for searching an angular region of a search volume, said method comprising the steps of: acquiring error information relating to a cue direction;from said error information, determining azimuth and elevation extents of the search volume about the cue direction;determining an angular extent of each radar beam in azimuth and elevation;from said angular extents in azimuth and elevation for each radar beam, determining a number of beams for covering an acquisition face of said search volume;determining a dwell time for each of the radar beams giv...
