Description
Frequency detection is a complementary method to optical observation. In some reported UAP cases, witnesses have described interference with nearby electronic equipment — car locks, radios, and in one documented case a radar detector responding during a sighting.
Robert Shiepe, a pharmacist and independent researcher, developed and used a modified X and K band car radar detector in this capacity. The device operates in the range of roughly 400 MHz to 4 GHz, with particular sensitivity at 1.3–1.8 GHz and 3 GHz. These are the standard frequency bands used by police radar and traffic control systems, but their sensitivity to microwave-band emissions makes them useful for detecting any source in that range.
Shiepe's documented observation at Marina del Rey, California, showed a radar detector mounted on a tripod responding during a sighting event. The method is described here as a supplementary technique — a way of adding a frequency domain observation to the optical record.
