Abstract
Apparatus and methods are disclosed in which a radar target can be electronically disguised to appear like another target. The technique is based on the generation of a desired synthetic target signature that is superimposed on the normal radar echo for the simulation platform. The simulation system consists of multiple antennas with tapped delay lines and signal modulators to provide the means of generating the desired target signal that is extended in angle and range. It is possible to utilize very realistic models of the desired target; the necessary information can be collected on a high-resolution measurement range. The general technique works against any pulsed radar in a monostatic geometry. A modified technique for operation against continued wave and bistatic radars is also discussed. The applications of the technique include the testing of missileborne guidance radars against cooperative targets and electronic countermeasures (ECM) applied to a target vehicle to deceive the radar. In either case, the physical target will be electronically augmented so that it appears like an entirely different target to the radar.
