The Rebecca/Eureka transponding radar was a short-range radio navigation system used for the dropping of airborne forces and their supplies. It consisted of two parts, the Rebecca airborne transceiver and antenna system, and the Eureka ground-based transponder. Rebecca calculated the range to the Eureka based on the timing of the return signals ...
The site is now closed, replaced by FAA/USAF JSS site at Rainbow Ridge, CA (J-83A), with an ARSR-4 radar. The road leading to the site was originally known as Hill Peak Road but at some point changed names to Eureka Hill Road. In addition to the site's radars, it also supplied ground-to-air communications to aircraft within its operating area.

Further development of this basic concept led to the Rebecca/Eureka transponding radar system. The only major change to the original beacon concept was to respond on a second frequency, to avoid the noise created by the original radar signal reflecting off the ground. This required a similar change in the radar to receive this second frequency.
