It has been recognized that Radar Guided Seeker and countermeasure development using flight test as a primary evaluation tool is costly and insecure from interception of signal and telemetry emenations. Radar Target Simulators have been developed which provide the capability both to evaluate actual radar guided seeker hardware and software and to evaluate Countermeasures against the actual seeker hardware in a secure environment. Experience with these simulators has demonstrated that with adequate simulator hardware, valid closed-loop performance evaluations can be conducted which will accurately reflect flight test performance. A critical issue in the implementation of such systems is the simulation of radar pulse range delay. This must be accomplished with sufficient fidelity to represent a range-delayed target or ECM signal credible to modern seeker signal processors. In this paper, various range delay techniques as applied to Radar Target Simulatiors are presented. In particular, a digital approach to the solution of the range delay problem is developed from basic concepts through actual hardware implementation.
