摘要：

A system is disclosed for generating simulated radar targets that eliminates the necessity for large outdoor test ranges and is relatively low in cost. The simulated radar target generating system provides complex targets of given simulated dimensions at given simulated distances when stimulated by signals emitted by the radar sensor in the sensor's operational frequency. The dimensions are simulated by the use of multi-tap delay device while the distances (or, range) are simulated by routing the signal, in the form of light, through a fiber optic delay of a desired length. This system, which costs less than $50 thousand, can be located as close as eight feet to the sensor under test.
