Abstract:
1. A computer implemented method for locating a radar search target, comprising: providing a radar installation with an array of adjacent beam positions diverging angularly from a radar transceiver coupled to a radar command and control processor, the radar command and control processor being operable for selectively activating transmitted beams and monitoring for reflected beams at least for a subset of the beam positions between limits of azimuth and elevation, the array of beam positions defining an acquisition face along one of a plane and a spherical surface, normal to a centerline of the radar installation and having an area increasing with range from the radar installation, wherein a time interval for activation of the beams defines a near and far range for the beams, between minimum and maximum limits of range; identifying using said radar command and control processor at least one search volume to be examined for a presence of at least one search target; projecting using the radar command and control processor the search volume onto the acquisition face and operating the controller for activating beam positions that correspond on the acquisition face to projected portions of the search volume; wherein said projecting of the search volume onto the acquisition face includes correcting using the radar command and control processor for differences of perspective caused by certain portions of the search volume being closer to the radar installation than other portions of the search volume.
