Describes the US Navy relocatable over-the-horizon radar (ROTHR). Electromagnetics, safety, health, security and environmental considerations are quantified and included in the specifications. ROTHR is a land based bistatic ionospheric backscatter radar system that can detect, track and estimate the composition of groups of ships and aircraft in a fixed annular sector with ranges in excess of 1000 nautical miles. Radio frequency energy will emanate from almost 1000 feet of antenna. This transit antenna will provide required gain and directivity. The receive system, with its large aperture, steerable beam antenna of several thousand feet in length, will be extremely sensitive. Bistatic means that the receive site is separated from the transmit site. Sufficient separation between transmitters and receivers is employed to provide continuous operations and to avoid system interference; however, a monostatic (single site) feature has been retained in its design to serve other functions as they become necessary.
