Abstract
A design study and investigation to determine the requirements for the mechanical and electrical components of a Radar Land Mass Transparency System has been performed. The technique consists of moving a laser beam across a 122 cm square transparency to simulate the side-looking radar system of an aircraft. The most promising system of those considered from accuracy, complexity and cost considerations is shown to be a horizontally driven transparency with a vertically driven flying spot scanner. The spot, in its vertical heading, scans out a strip 5 cm wide. Spot size can be kept to 2.5 microns over the 5 cm scan length at any location on the transparency. Smoothness of motion to simulate an aircraft is achieved through a feedback control system designed to move at constant velocity. An overriding position loop will correct for any accumulated errors which could result from environmental or load condition changes. A position accuracy of plus or minus 0.00127 cm over the entire transparency is shown to be quite feasible. In addition, the speed range from low flying aircraft to satellites of approximately 100:1 is also shown to be feasible using the same system. Mechanical and electrical components chosen for performance calculations and tolerance determinations are off-the-shelf. These parts are easier to acquire and lower in cost than equivalent custom made components.
