DISPLAY FOR A FORWARD-LOOKING RADAR
Abstract
A display has been implemented for a proposed forward-looking ocean surveillance radar for a manned orbiting vehicle, and test results were obtained for simulated target signals. The display is a folded range sweep format, which is a B-scan presentation where the 135-nautical-mile range axis with a resolution of 10,800 range elements has been divided into 18 equal range segments with the individual B-scan segments placed adjacent to each other. Each segment retains the full angular coverage of plus or minus 30 degrees with a resolution of 30 angular elements (2 degrees each). This arrangement forms a square pattern and thus provides maximum utilization of the crt resolution elements. It provides a target location prediction technique, since the relative target-to-satellite velocity is such that successive scans of the radar will cause the target to be repeated in successive segments of the display (range decreasing).
